exactly Harry

 

I am enjoying the tunes just fine on my 282/HCDR.

 

will I stop my music enjoyment in the wait for a new preamp range which may or may never be here. Never.

 

I already made my choice buying a 282 instead of a 272 with the new volume control.

 

music (for me) comes first, don't care much about the lights on the volume control or the range of it. 

 

If I had to "slum" it with a 20+ year old NAC42.5/110 I would gladly do it.

 

LOL "slumming it", no such thing with any naim actually.

 

"slumming" it is listening to music on the latest 9.1 channel AV amp which can't play a tune properly.

ok, we'll see...

Woa  !

 

Still need analogue inputs here. CD ( very important) , sometimes two at once if comparing. Not meant to be ideal -I know,  I've heard this. Possible turntable in the future. Still got tape deck with lots of old treasured tapes too. Also connect an AV processor left/right into as part of a home cinema set up.

 

And  the NAC 52  sounds rather marvellous of course. The beating heart of my system.

I may go to a 552 a way down the line.

No need for all this digital input mularky. 

Ok , maybe one would be nice for my tv optical out stereo only.

Can feed this optical out into my old Benchmark though. Then into the 52. Probably sound better than most pre's with an internal Dac to boot.

 

Long live analogue inputs I say.

Right on. And for someone like Beefster above, the inevitable pensioning off of the current 552 dinosaur will create a wider choice for second hand stuff which at its price point will still be superb and possibly peerless. Just like the 52 is at the moment.

 

Those of us who are happy will stick. Those who have the need or illness will have a new solution or cure. Those who have been waiting for for things to descend can hold their arms out. Everyone wins, including those who do nothing, who strictly speaking will simply continue to win.

As one who uses Hugo direct into power amp, I agree up to a point - but many people have other sources that they want to be able to use through the HiFi, whether that be analog record players, or anything else (e.g fm radio, music keyboards etc). I nearly included digital as one of the other source types, but arguably if the basis is a high quality DAC with volume control, what is wanted is switchable inputs to the DAC to take, for example, the cd digital output - or outputs if two are used as one person said, and allow switching between them and any streaming source(s).

 In my case I have the annoyance of having to unplug the DAC from the power amp and swap to the preamp when I want to use other (analog) sources, with appropriate power down first, however that is a minor price to pay for the benefit of the direct DAC connection, given that I don't do it often.

In my experience a two box analog preamp always gives the biggest sonic upgrade in my systems over the years. I cannot understand how this extremely essential component can be taken out of the chain and not affect sound quality.

These arguments do get polarised - along comes the 272 with a new volume control - of which I was blissfully unaware! - and the old products are redundant.  Urm here I don't think so.

Posted on: 11 November 2015 by analogmusic

I tried the Hugo into a NAP 100, but somehow to me it sounds like a Naim power amp needs a naim preamp to sound at its best and vice versa, a naim preamp needs a naim poweramp

 

I reached that conclusion when running my DAC V1 into very good dynaudio active speakers, something was missing.

 

Hugo into a naim pre/power sounds very good

I wouldn't mind a full range volume control. The mechanical pots currently in use have a narrow range to say the least for many users. Was it the first Naits that had a full range volume control? Or maybe one of the early pre amps. Something did - but not for long. I read it in a HiFi magazine article some years ago. Apparently the full range knob went out of fashion across the industry because in showrooms it didn't make the amp seem powerful enough and it became more of a convention than an absolute necessity, even allowing for a multitude of input levels, of which there were many admittedly.

Whatever Naim do with the future, I just hope they don't go down the same road as Linn. That company made excellent separates but it seems now they are trying to stay in the hifi business but get out of the separates business.

The benefit of separates was not purely sound quality. If something goes wrong on my system I can get a box fixed and find something else to fill the gap in the meantime. Try that when that Chakra power amp stage in your Linn Exakt Akubariks plays up. Its a double edged sword. Less to go wrong with low box count integrated solutions but bigger impact when they do and less upgrade flexibility. For those reasons also, I think products like the 272 and Uniti represent new categories for unsatisfied niches. Not the direction 'everything' will eventually move in. The market is still too heterogenous for that.

If changes happen to the preamps maybe the classics are axed and maybe they aren't. But it seems likely there will be analog Naim preamps in the forseable future either way.

I think Linn have done very well and many of their strategic direction changes (including the odd publicity stunt) have played out well. Their control software is better than Naim's also. But the really big thing is the musical ability. Linn still provides it in spades. I slightly prefer Naim. Helen more strongly prefers Naim. So we're sticking. Personally I don't think Linn have lost the plot they are interested in and the sound quality has not suffered. We could happily go there if we had to. But we don't have to.

I thought it was because with the advent of digital sources, the input levels to pre-amp are often too high (at least, IIRC when I used to have a vinyl source, the volume contrl level for that was significantly higher than for CD source for the same acoustic level). Regardless, there needs to be headroom for someone playing at a high level in a larger room with less efficient speakers (within limits of general system compatibility and balance).

Technically, pre and power amplifiers as we know them are false distinctions: 

 

Essentially the amplifying chain is there to increase the magnitude of the original electrical signal to something with enough power to drive the loudspeaker, taking into account source and sink impedances. There are many actual stages of amplification in the electronic circuitry involved, each raising the signal by a certain amount. At some point a volume control is inserted to avoid everything going through with the same amount of gain, to give the listener control. This is usually at some intermediate signal level, balancing the negative aspects of different positions.

 
Where there is a need to correct some aspect of the signal, e.g. to reverse a pre-emphasis or de-emphasis as frequency increases or decreases, such as used to minimise some limitations of vinyl records, that circuitry has to be included somewhere, and is commonly inserted in the low-level stages of amplification. 
 
Splitting the amplification system into two parts (pre- and power-) is not necessary, but has some benefits, enabling design focus on different challenges (e.g minimising introduction of electrical noise at low signal levels, and the need to dissipate heat at high signal levels). And if the volume control is put in the pre-amp part, splitting off the higher power stages into a power amp also facilitates either different powers of power amps for different room/speaker requirements, or multiple power amps, e.g with an electronic crossover for bi- or tri-amping.
 
Ultimately any decision as to the point at which such a split is made is somewhat arbitrary, though there has been some standardisation, which makes it possible to 'mix and match'. That standardised level is very similar to the output level of many DACs, so that actually the term pre-amp becomes a bit of a misnomer, in that it is no longer amplifying, but simply controlling (with the volume control), possibly impedance matching (depending on power amp design), and allowing selection of other inputs if desired (which may be low level and thus amplified). The  pre-amp may also do other things like limit frequency bandwidth, which I understand is the case with Naim, limiting to 40khz, though whether that is necessary or appropriate depends on the source and the power amp. The pre-amp may actually include an attenuating stage to reduce the DAC's input signal low enough for other circuitry to handle, and then re-amplify.
 
So, if the DAC has a volume control not adversely affecting audible SQ - or if the  power amp does (some do) - and if the DAC's impedance is appropriate and frequency bandwidth already limited if needed, it can happily feed a power amp directly, avoiding the extra circuitry of the pre-amp.

I guess it is bound to vary depending on what is being fed in to what. Back in 1979 my A+R A60 only needed to go to about 10 O'Clock to rattle my windows when fed with a MM cartridge or a cassette deck. When CD players arrived this nearly halved. I have never used an amp or auditioned one at home or played with one at a dealer since 1980 that required anywhere near 12 O'Clock for TT/MM/MC, open reel, cassette, CD or DAC. There must be combinations of sources and amps that require a big twist of the volume control to get going, I (or anyone I know) just haven't seen such a combination.

I feel the same way when I come home to my Hi Cap DR/282--PMS Tri Amped 250 Briks.

I think Naim Amps really perform at their best when they're not required to handle the whole frequency range.

Hence, Bi Amp/Tri Amp mode, and of course the 1% of those who choose the Active mode!

@Harry, I don't mean to imply Linn have lost the plot and don't want to be misunderstood here. They make excellent systems of extreme quality and the course they have chosen seems to have business sense. But they are for a diffetent type of consumer now. There was a lot of overlap with the consumer type in the past.

Currently, a consumer who's only interest is sound quality (whether provided by one box or six) is the only consumer that both Naim and Linn can appeal to. For consumers where
sound quality is the most important factor, but not the 'only' important factor, their target is different. Since resilience and upgrade flexibility are also high on my list, I decided Linn had gone down a path I just couldn't follow. When I chose my system it was between Naim and Linn but they had not yet dropped preamp production. However Exakt was around and the direction, while fascinating and well thought out, was limiting to me. So this is why I don't want Naim to go down that road. I'm still very much a separates person.

@various, can someone please educate me as to what changed on the 272 volume? By full range are you just referring to that change in input sensitivity? Or is this referring to a change back to linear pots instead of 10k pots? If so, I was never aware they had moved away from linear pots.
Posted on: 11 November 2015 by hungryhalibut

The 272 has a digitally controlled analogue volume control. The volume rises smoothly from 0 to 100, so it's much easier to make small adjustments, rather than reaching virtually full volume by 11 o'clock on the other preamps. The volume control is just like that used on the SuperUniti and V1, and presumably on the Statement. It really is a delight to use.

^ what he said.

 

The volume pot on my 552 is nearly a case of all or nothing. On out Mu-Sos it's so easy to make slight adjustments and it feels much slicker and nicer to use manually.

Naim - like just about everyone else I believe use logarithmic potentiometers (whether analogue or digital) for volume, ie the resistance changes a smaller amount at low volume and higher amounts at higher volume. If it was linear it would be even harder to control at low level. Volume changes logarithmically not linearly.

 this is saying is either that the preamp output seems to be too high for the given input (whether that is because the source output is higher than the rated level of the input, or the gain of the preamp is too great), or the power amp gain is too great.

 

In effect what t his is saying is either that the preamp output seems to be too high for the given input (whether that is because the source output is higher than the rated level of the input, or the gain of the preamp is too great), or the power amp gain is too great.

 

One thing that has happened over the years is a tendency towards higher powered power amps ( or maybe that's the process of an amplifier upgrade path. But rather than being a statement of the maximum power an amp can give, power amp output power rating is most commonly is stated for a reference input level ( from the preamp), typically between 0.5V and 1v depending on the manufacturer. So a more powerful amp generally will have more gain not simply more 'headroom' than a less powerful amp (i.e. it will amplify more) .  If the rest of the system is the same, that will require the volume control setting to be lower for the same sound level.

 

Ideally a single-turn volume control should allow smooth graduation from the lowest listening levels, to the highest that it might reasonably be anticipated anyone would use an anticipatable pre-power combination, so one might expect "typical" listening levels, whatever that is, to be somewhere around the middle of the range, I.e around 12 o'clock. So maybe higher powered hifi power amps (as opposed to those used for PA systems where the extra power is wanted as extra volume) should have reduced gain, still giving the desired headroom but letting the volume control -and preamp - behave as designed. Some pro power amps do that with input gain controls to allow custom setting.

I've always thought that the 202 looks aesthetically so much better than 282 and upwards - cleaner lines, fewer buttons...

I'd love to see naim boxes without buttons and lights, just controlled remotely by the app in future.

So there we have it! A 252 level, shoebox sized analogue preamp with digital control and just one input. Design by committee is a wonderful thing. 

Posted on: 11 November 2015 by Harry

That's not what I voted for. Committee functioning normally then.

Posted on: 11 November 2015 by Allante93
Maybe I'm missing something or just old school, but I love to turn my volume up and not knowing where am at until desire volume is reached. Of course it depends on the recordings, but generally, when was bi amped generally maxed out at ten o'clock.
Now that I'm  tri amped maxing out at nine o'clock.

If this new digital volume control, or what ever doesn't add to the sound quality, I for one would be content with no change. I imagine that the new technology would cost a few pennys!

Just my thoughts!

That's right, this is democracy in action. Prepare to be disappointed. And as for that snazzy volume control, it would be an optional extra in a separate box - complete with its own NAPSC.
