AV2 Wannabe seeking experienced advice pls
Posted by: Johns Naim on 16 February 2003
Hi All,
Quite some time ago I investigated adding on HT to my 72/HiCap/180/SBL's. The best that I heard, and undoubtedly the ideal solution was the AV2/175 combo. However, thoughts at the time were that the picture side of the overall involvement factor re HT/Movies was just as important as the audio.
Consequently, I felt I could make do/get by with a slightly inferior sound to the AV2/175 combo, re the addition of a cheaper external processor, or even a receiver used for the purpose. Like most, one has to make decisions based on priorities determined by available resources, as well as taste.
Given the choice of being able to afford either AV2/175, or, but not both, going for a new 250, and hopefully eventually active, that would be my prefered route, as I find music more enjoyable/rewarding overall, than HT, which is not to say that I don't enjoy HT, but simply having to assign priorities re expenditure.
I've assessed/auditioned a number of options, including Denon, Rotel, and Sony, my personal choice being the Sony TAE/TAN pre-power processor/amp combo. I'ts a little on the 'slow' side, re PraT for my taste, however that seems to matter slightly less, or perhaps is less noticeable when the soundtrack is predominately dialogue, sound effects etc, and it's a much more natural sound re smoothness, dynamic graduations, clarity, detail and timbral accuracy than the competing receivers, including Sonys own.
I've let the whole thing drop for quite some months, as there have been constant rumours of an forthcoming update to the TAE, to give it DPL11, which I would quite like for my existing VHS cassette collection, but the latest news is that here in OZ there is a new model coming, but not till July/August, and is reported to be a receiver, - no doubt with many more bells and whistles, but very debatable improvements in sound quality I should think.
Suddenly the whole thing has come back into focus for me with the opportunity to buy a new unit, at a price 1/3 that of the AV2/175, which would also allow me to fund a new computer as well, which will hopefully do wonders for my level of day to day frustration
So, to stop rambling, giving background etc, and to cut to the chase.
Has anyone had experience coupling either a separate processor, or perhaps receiver using the L&R preouts to the Naim, other than the AV2?
The specs of the AV2 don't mention what it's output voltage is, whereas the Sony, and also the Rotel output 1V, into 75 Ohms.
I'm assuming this would be similar to the AV2, as I figure there must be some sort of standard on this. As the Naim inputs are 75 ohm and for instance the CDI outputs 2v into it's CD input on the 72, I don't see any problems coupling a processor with a 1v output into one of the tape inputs of the 72.
Could anyone comment on this please?
Also, I see on the AV2 manual, that Naim recommend setting the volume control to around 12 o'clock when channel balancing using it in combination with the 72, 82, and 52, as they don't have the unity gain function of the later preamps.
Would this be the same with the Sony, ie needing around 12 o'clock on the 72's volume?
Lastly, I have read of some problems here on the forum, re hum using the unity gain function with the lastest preamps.
Has anyone done what I'm proposing to do, or had experience with this, re hum, or other mismatch problems re earthing etc, using a non Naim processor add on for HT?
Thanking you all for help/advice in advance, as I do need to make a decision quite quickly, and need some reassurance as to the matching etc re the loads, hum, earthing etc.
Cheers all,
John.

quote:
The only advice I can offer is to use a Yamaha E800 processor, at around £300 it's a bargain! It works well with my 102/180/shahinian arc set up with Dynaudio audience 42 center and rears.
Another bonus is that later you can add the naim 3 channel amp and the Yamaha shuts it's own down automaticaly, leaving you with the processor function only, which is what I plan to do, with the next move of replacing it with the AV2.
It's much better than Sony stuff, and enabled me to afford a Panasonic plasma display now - which is the real benefit.
Thanks for the info Dillion. I take it you don't have any problems with level mismatches, hum etc, and also do you 'have'(?) to put the 102 volume up around 12 o'clock when using the E800?
I agree the Yamaha is very good, having had a CA800 amp many years ago, however unfortunately it's not available here in Australia.
However, using a receiver with pre-outs, and utilizing the inbuilt amps to drive center and rears achieves pretty much the same thing it would appear. Ditto with the Sony TAE/TAN AV pre/power combo I'm interested in.
It's actually quite flexible, in that there is a separate processor with the prerequisite pre outs etc to run L&R front to the 72, and hence 180/SBLs, leaving the Sony power amp to drive center and rears. The Sony power amp is seemingly quite useful for my situation, as one can run it in various channel combinations, ie in 2,3,4,or 5 channel modes, and bridged 2 and 3 channel modes, thus being able to give more power to the rears etc, or in straight 5 channel mode in a standalone situation.
It's very hard for me to say whether Yamaha is bettter than the Sony, as typically, one cannot find a dealer with all the various brands/models in stock to do a decent A/B comparison. All too often all one can do is foot it around various dealers, and listen to what they have to offer at various price points, and see what one likes the most. Certainly most brands do seem to have something of a 'house' sound, and I do like both Yamaha and Sony, for HT, but couldn't seriously make an absolute judgement on it, not being able to do a direct AB.
I've had Yamaha before and liked it, and now I have the Sony 9000ES DVD player, and am exceptionally pleased with it, re sound, build quality, and ease of use, notwithstanding of course, superb picture quality.
I was able to A/B Denon, and Rotel, and it was a toss up, the Denon being a bit more dynamic than the Rotel, but with a rather bright and generally listless sound. The Rotel was very dark and rich in its tonality, detailed, but again quite 'slow' sounding.
My Naim dealer stocks the Denon, Rotel, as well as Arcam and Naim. Surprisingly, when first investigating adding on HT, I tried both the DVD88 Arcam, and the then AVR100. Whilst they were great for music, and would do a one box solution well if you wanted both movies and music, they did not impress me overly much on movie material alone, which is my prime purpose for wanting the gear.
I heard the Sony several times, at different dealers, and privately at a friends home. It leans towards the bright side of things, with an exceptionally detailed, but somewhat lazy sound re prat. However, it is also smooth and quite refined, particularly in the midband. Whilst not as good IMV as the Arcam for stereo, it has a much greater sense of surround field size, scale, and ambience, a real sense of grip, control, power and ease, and dynamics as in go to whoa and all the microdynamics in between, albeit whilst not quite possessing the rythmic prowess of the Arcam, on movie soundtracks, which made it the most involving listen overall when heard in various situations viewing movies.
I spoke to my dealer today re the questions I'm asking here, re hum, mismatches etc, and he was unable to help, as most customers apparently just went for a separate system in their experience.
Whether I upset him or not with my intention to go with a Japanese AV pre/power I don't really know, but in his opinion, only the AV2 and the Arcam made any sort of decent sound with movies.
Hmmm, I sure hope I'm making the right choice here
I'd love the AV2/175 combo, but at AUS $11,000 it's out of my reach at the present time, with other commitments, and priorities with my 2 channel set up.
Still, I'm inclined to think that AV is a bit different to HiFi re the sound requirements; certainly the Sony has almost endless adjustment possibilites re setup etc with bass management, a parametric equaliser per speaker channel for fine tonal balance of any speaker mismatches etc, which is something the Arcam is quite weak on by comparison.
Hopefully, in time, I'll be able to upgrade the processor to an AV2, or it's successor, and run it initially with the Sony amp, and then add the 175 later on as funds may allow. In between, I hope to be able to invest in either a new widescreen plasma, or possibly O/H projection, and hopefully going to active with my Naim HiFi. All in good time.
But yes, I think you went the right way with going with the E800, and putting the money towards the plasma display. I hope to be able to do something similar, as it is becomming all too readily apparent that to do HT REALLY well, like an AV2 etc, involves a lot of extra investment over and above one's 2 channel set up, and it takes time to build it all up.
I have to confess that part of the attraction to the Sony is it's price. The AVR is UK 800 pounds, and AUS $3,000 by the time it gets here with all the shipping costs, tax etc, and mostly exchange rate losses. And there is no real discounting. Fair enough. By contrast, the TAE/TAN retails for UK 2,300 pounds, and AUS $5,000 by the time it reaches the shops here. However, Sony do discount, and I've been quoted in the region of AUS $3,500 which is an outstanding value for money buy IMHO.
I have a fairly strong Euro bias, re sound philosophy, however Far Eastern equipment, particularly in the HT arena, is much more competitively priced here because of exchange rates and shipping etc.
And certainly in the context of sub MP3 quality movie soundtracks, the sound quality differences hit the law of diminishing returns very quickly indeed as one advances up the price ladder, and the differences between the various HT processors etc, are relatively small considering the differences in cost between the so-called High End specialist euro product, and the more 'mainstream' Far Eastern one.
Indeed, with global manufacturing, the Arcam AVR100 was built in China, with an almost identical circuit layout to an NAD, and yet sold here for twice the price, according to an article complete with interior photos I read once on the net.
So in the absence of being able to contemplate the likes of the AV2 at the present time, a mainstream processor makes a lot of sense to me anyway, over a differently, but not necessarily better sounding, european imported one.
Anyway, I'm starting to have a little rant/diatribe here, which was not my intention, however I guess whenever one is poised to make a purchase, one goes through all the ins and outs of it all.
If anyone is able to share any more experiences re the hum, or earth problems with add on processors, such as the E800, or receivers, please lets know of your experiences. Also as to the need or otherwise to set the naim preamp volume to around 12 o'clock when balancing up the levels with the add on proccessor.
Thanks for listening, and sharing, and my apologies, re this somewhat long winded post.
Cheers,
Peace to All,
John.

Hi Greeny,
Thanks so much for your informative and very helpful reply.
Curiously, the Naim AV2 manual recommends setting the volume of the likes of the 72, 82 & 52 etc, ie models without the unity gain feature, to 12 o'clock to gain the maximum dynamic range as they put it.
Apart from risking trouble accidentally switching back to CD with the volume so high, have you either tried, or noticed any gain, or loss by having the volume up so high?
Certainly, I seldom, if ever go beyond 9 o'clock on CD for loud listening, and was wondering about this 12 o'clock setting re the so called unity gain.
I'm relieved to hear that you've had no hum problems. I was thinking of the star earthing etc that Naim use, and combining it with other equipment.
Yes music is definitely the priority, although I do enjoy my movies, and like to feel caught up in them, all that childish escapist stuff - good fun
I haven't mentioned a sub, as I'm on a rather tight budget, and I figure best to go for the likes of a REL, either the Q400, or the Strata 111 would interest me, but will have to be an upgrade for a little later.
Much as I'd love to, I can't afford to do it all in one hit unfortunately, so will be running sans centre channel and sub in the initial instance. And lesser subs would just be a waste of money IMHO.
Having said that, I'm hoping that careful use of the volume control, and bass management, will avoid any potential problems of overloading the drivers of the SBLs with excessive bass.
One can choose the low pass setting on the Sony processor, as well as setting the level/output of LFE, as well as turning the LFE off. (Which will not then route it through to the SBL's) Also I can attenuate the level of the bass for each channel via a 3 stage parametric equaliser - horrible things for stereo, but in the digital domain, and for HT, could be quite useful at avoiding blowing up the SBL's with dinosaur footstomps etc
As a matter of interest, how do you find the SBL's for HT? I've read criticisms of them elsewhere for that use, however I'm presently listening to my DVD's via my Sony DVP S9000ES's analogue outputs to the 72/180/SBL's, and the sound is superb IMHO.
Still, the downmixing of 5.1 to 2 channel prologic compatible stereo in the player leads to dynamic compression, and loss of information due mixing and level mismatching inherent in the downmix process, so I'm hoping the 'full McCoy' of DD will be a big advance in dynamics and clarity.
I hope this is going to be fun, urk, I might cease to become a music lover, and become a movie couch potatoe instead. Nah, only kidding
Thanks once again Greeny for the most helpful comments; it's appreciated.

Hello All,
Gentleman, my apologies for taking a while to get back to all those who most thoughtfully, helpfully and kindly wrote in.
Well, my lounge is now adorned with the addition of two golden babies, to wit a Sony AV pre power combo.
First impressions:
Well, to some folks, Sony as a brand is linked with the cheap ghetto blaster down the street, but their so called 'high-end' ES range certainly does the business as regards the intial presentation/out of the box experience. Not a finger mark, or flaw to be found, with seams and joints just so precise, volume pot knobs etc perfectly centred in the fascia cutouts etc; the overall finish and build quality is a joy to behold.
Actually, battleship is a bit more like it, as both pre and power, are made of 2mm thick steel, copiously copper plated and with copper screws etc, to ameliorate the affects of EMF - albeit I think non-ferrous materials would be a better material overall to build with, in that regard.
Not quite in Krell class re weight, nonetheless at 54 pounds, and a fairly bulky box, the power amp was a two person lift to get it safely handled inside. Phew!
I've never been a fan of gold, however, chamagne as it is called, is nearer to the mark, as it doesn't have that overdone brassy/yellow look some 'gold' products have, thankgoodness. The button/knob count is very low, and the overall effect is of understated luxury. Setting off the cake, is the touch screen remote, apparently it has a fairly heavy battery consumption, but the convenience re the inbuilt macros switching on the DVD, amp input, TV etc at the same time is a bit nifty, especially for someone who has a non-remote controlled 72 preamp. Remember those days?
So, it is installed, running in, and I am learning to 'drive' it...
If all this glitter was no more than skin deep, I would be in for some disappointment, but so far the integration with the Naim, and the overall sound is very, very good indeed. Some would say superb, but I think I'd reserve that particular adjective for the AV2/175 combo.
No, it's not as good as the AV2/175, but there'd be something very wrong if it did, as the AV2/175 is more than twice the cost at full retail, and one would want something more for the additional outlay. Having said that, noting the differences, playing my selection of 'test' DVD's and mentaly comparing (always a bit unreliable, but a physical AB was not possilble) it struck me that the major differences were in the way the Naim handled rythmn, tansient attack, as in the way things/sounds would start and stop, ie control, and resolution, in both detail to be heard IN a sound, or voice, and particulary the separation between sounds, voices etc, and the spatial perspectives thereof.
Nonetheless, where I found/am finding the Sony twins very satisfying, is that whilst it's hard to quantify these differences, I get the impression the Sony is giving a very large slice of what the AV2/175 has to offer in terms of the end result, ie INVOLVEMENT in the total movie 'experience' - perhaps as high as for arguments sake, 85 - 90% or so. Importantly, I found whilst playing back my favourite test discs, and listening/evaluating intently, that I had trouble maintaining my concentration on such abstractions, as the overall level of performance was such that I was forgetting my analysis, and simply getting very caught up and involved in the movie: holding ones breath, clenching the arms of the chair, gritting ones teeth etc - you get the picture..
Menace, was, well, menacing, and excitement, was just that. So all in all, I'm a rather happy camper re my first real foray into the world of HT, whilst recognising that there is better out there. Maybe one day, when I've gone active, and upgraded to a new 250, or 300, maybe then I'll do something about the AV2, or whatever it's sucessor may be, but for now, these golden twins are proving very satisfying indeed.
Just a final remark on the hum, and balance levels. After connnecting everything up, I set the speaker levels using the test tones, setting the Naim volume to 12 o'clock initially. However, with everything balanced up, as soon as I turned the TV on, I got a sort of buzzing hum, not a particularly loud level, but enough to be annoyingly discernable, so I figure it's either the TV electronics generating some sort of interference, or an earth problem relating to it when connected to the rest of the system, and switched on.
I haven't tried playing around with leads as yet, to try and isolate the problem, but managed to find a more than adequate balance of speaker levels with the vol. pot of the 72 at the 9 o'clock position, and the rear speakers set at -17db. At that, with the master volume up around -25, there is more than adequate volume on movies, and no discernible hum.
So all in all, I'm very pleased. Hope you'll excuse my rambling 'mini' review but I did want to just write in and let you know how I got on, as I was very appreciative of all the helpful advice received earlier.
Cheers,
Peace to All,
John.

Hi All,
Thanks for the suggestion Gusi. I'm just curious. In my situation, with everything wired in, there was no hum. However, turning the TV on, brought hum. Note that even though plugged in, and on 'standby' there was no hum; this only appeared when it was actually swithed on.
Is this likely to be a hum problem re wiring which I should investigate further, or is it the HiFi picking up some sort of RF or other intereference from the telly?
Cheers
John
