The 'Slab' Effect

Posted by: Ade Archer on 02 December 2000

I have had a pair of AVI Bigga-Trons on the end of my Naim/Linn for a few months now but have only recently turned their location into a proper listening room ( it had become a sort of dumping ground). The fireplace has been knocked out, an arch built and the equipment all set up properly. The problem is I have'nt felt the speakers delivered in the same way they did in the demo room, the only way I can describe it is the music seemed contaminated or coloured in some way, messy would be another way of describing it. I recently added a Hi-Cap which improved the level of detail but did'nt really tidy the sound up enough. I was fed up with moving the speakers a few inches this way and a few that hoping to find the "sweet spot", so with nothing to lose I bought 2 paving slabs and placed the speakers on top (they sit on bloody heavy Target stands/ Pulsar Point feet) and I have to say that the improvement is as much as I got adding the Hi-Cap.(a reflection of how bad the floor was) The equipment rack sits on a concrete base where the fireplace was but the speakers are on a suspended wooden floor.
Anyway I'm going to start distributing my "Mani Sound Bases' as I've decided to call them in the near future for £175 pair. In all seriousness if I had got this improvement after spending £200 on something I wouldnt have been disappointed. Just goes to show you that... , well , I don't know ,...but it shows you something. Ah, that's it, start with the cheapest tweak and move upwards!

I have never tried Pulsar Points with Biggatrons. Are you sure they work? We only ever use blutack under the Biggatrons and the sound is anything but messy. Try them without...

Regards,
Frank.

Thanks Frank,
My Biggatrons are sitting on blu-tak on the top of the stands. The Pulsar Points have replaced the spikes on the base of the stand. I knew from the original demo that they should'nt sound messy, that's why I kept experimenting, but the problem was obviously with my floor, not the speakers. They sound fine now.
I've also got a set of them (PP's) under my CDX, and they do a good job, but then I've only got a very modest rack. I'm sure if I got a Hutter, Mana etc under it I would,nt need them, but that would also cost considerably more than £50.

A good rack is the next step, but room layout means I need at least a five tier (preferably six, for adding an XPS) rack to put everything except my LP12 on (that's on a wall shelf above the rack), but also I want a "fit and forget" rack, so I don't think Mana is an option, everything has to fit in the space under the LP12 so all those "phases" are'nt an option, and I would then feel I was missing out.

This new Isoblue stuff seems interesting, if for no other reason than cost, and recent posts seem positive and there's also a dealer in Brum.

This forum usually has an answer for everything, but equipment supports, well that's another matter!

Ade,

I recently found when I took the carpets up on my floor that the floorboards are a long way from being ideal - old and spongey would probably be the best description. As a trial (based on seeing this on several set-ups), I bought a couple of the heaviest paving slabs I could find, and put my speakers (Wilson Benesch Actors) on top. Undoubtedly this was a more stable than previous. However, in my situation, I found the slabs to totally ruin the sound, the most grievous fault was that the bass seemed to lose all subtlety in favour of more slam. As ever, you have to try all these things yourself and see what works for you.

Hi Lerxst(Lerxxst?),

Quadraspire is another option, but the impression I get from various posts is it always seems to come out worst in the Mana/Hutter/QS etc comparisons (and look like 1970's coffee tables, but then one of the most highly rated alternatives look like oil rigs) Having said that, it's the only one I'm likely to be able to dem at home as my mate at the dealer stocks them (Money-Back Guarantees notwithstanding), so compared to my budget rack it's bound to sound better.

When the time comes I might try to talk Griffin Audio into lending me the Isoblue as well so at least I can compare different makes.

I'm sure that in the view of some others you've done the unthinkable, replacing Mana with QS, so could you elaborate when you say it sounds better.

Vuk,

From what I can gather our friend with the QS previously used a 5 tier Mana stand. He has given his reasons why he changed to QS, he preferred the presentation of QS to Mana.

All this, IMHO, he put forward in a very eloquent manner.

This poor chap is now sentenced to a boy band & is accused of being a troll. He looks like a victim of the 'Vuk kangaroo court' to me.

FWIW I prefer Hutter to Mana for similar reasons to Lerxst, & yes I have lived with both.

Lerxxst,

You stick to your Quadraspire Stands and don't let Vuk bully you around. As far as I know Vuk hasn't even heard the Quadraspire so his comments can only be taken with a pinch of salt. I've been doing a bit of stand evaluation myself recently and can certainly see where you are coming from in liking the Quadraspire.

You don't mention what mains block and leads you are using. If you are a follower of the Audio Councel school of setup, then the Quadraspire stands are generally used as an integral part of an overall setup philosophy that also includes the MusicWorks mains block and leads.

I've heard the QS/MusicWorks setup used with CDX based systems (typically CDX/102/180) on a number of occasions and I've always been extremely impressed with the results. I have absolutely no doubt that this kind of setup has serious music making abilities that would easily shame many much more expensive systems.

Hi Vuk,

OK, I will be the first to go along with using one's real name on this forum. That is one of the reasons why I don't think I will be posting on the 'other' forum in future.

I'm fairly sure that Lerxxst is not a proper name & I personally would appreciate some form of de cloaking in future. Lerxxst has only posted a handful of times here & maybe is not familiar with the house rules.

What I have a problem with, & I hate to say it is becoming increasingly more irritating for myself & others is a handful of Mana 'fundamentalists'. I personally place yourself on the fringe of this & not a hard core member, who seem hell bent on ramming their worshiped product down everyone's throat, whether or not an initial enquiry actually involved supports or not.

Mana is good, I've never disputed that, but it is not for everyone's taste. I have a good fried who tried some of my Mana at his home and found the effect too up front & in your face. In his opinion the Mana effect is just that , an effect, but not a musical benefit. I think he is now considering a more mellow approach with some
wooden stands, & no, they are not Hutter.

There are many good support systems out there. Hutter & Mana IMHO are two of the better ones, but there are others to suit different preferences in presentation and budget.

I am quite prepared to believe that Lerxxst once owned Mana & now prefers QS, fine, they are both good stands that go about the music making business in their own ways.

I personally do not believe that there is a Mana/Hutter feud. What I do believe is that a small minority of Mana users are totally blinkered to the possibility that another make of support might be suitable for another person.

I will be out of circulation for a few days, so nothing personal if I don't contribute to the forum for a while.

Seasons greetings,

Bo

I have no explanation for why some are hearing this, although the obvious one about improper setup seems in line with their observations.

Perhaps it's because others are listening with THEIR ears and you are listening with yours. I've heard stuff (ok..at shows) that has driven me out of a room it was so bad. Yet there have been people sitting there with big grins on their faces because they like it. What you find to be very good someone else may easily find 'hard' and 'upfront'.

Vuk--

Or it might just be that his perception of the sound is different from other folks. An audiologist friend of mine says there is more difference in hearing from one person to another than from Naim to Krell or Hutter to Mana. Food for thought.

Che ers,

I don't 'stick' with anyone, I simply have my own point of view. I'll give you a quick example. My brother thinks that SBL's sound very bass heavy. I've read more than one post on this forum accusing SBL's of having no bass at all. I find it unbelievable that anyone finds SBL's either light or heavy in the bass! Nevertheless, people do think this. All I am doing here is pointing out that we all hear things in a different way and that you should just accept it. Why does it matter to you if someone prefers the floor to Mana?

It was suggested by David that your definition of 'boybander' is someone not posting their real name or their fullname. Since I do both, (just check my profile), I'd suggest a more accurate definition is someone who doesn't agree with you.

I've already mentioned my space limitations, so through necessity I need a six tier shelf (including the top) for my gear. Could anyone enlighten me what the rough cost is of this spec from Hutter/Mana. It's also got to be about 30" or less in height, this means certain racks might not be an option if they have tallish shelf spacing.

The slabs did great things under the speakers, but I'm having difficulty constructing a rack from six garden slabs!

Well 'Vuk' may be a real name, but @Edge of the Earth' is a pretty evasive address.

While doing the Christmas shopping , I bought a number of marble cutting boards out of curiosity and stuck them under my hi - fi.Incredible effect - They come in two sizes - one is perfect for a 72 / 140 / hi - cap . (These are £3.99 each or three for the price of two) , the other fits under my cd3 (£6.99). I went back and bought some for under my speakers (Royd Abbot) with another improvement . I then got one for my girlfriends cd player .The staff at Woolworths are giving me some strange looks so may have to lay off for a while.Cheers.
Posted on: 17 December 2000 by Ade Archer
Tony,

can you explain exactly how you've used these boards, it sounds like you've placed them directly under the equipment. If this is the case, what rack etc is it all on. (I'll try anything if it's cheap)
What improvements did you achieve?

Ade

Posted on: 17 December 2000 by glenda
A bit of a cheapo Apollo (I think - about £125 ) - a mixture of metal and plywood . Perhaps my rack has been crap all along and letting down my system - cd3 / 72 /140 . A lot tighter bass and more definition are the outcomes . I have spent most of the weekend re-exploring my cds - Massive Attack sound like a completely different band . I keep thinking that I am deluding myself - can somebody just buy this lump of marble and verify my ears!!Cheers.
Posted on: 17 December 2000 by Ade Archer
£125 is still more than I paid for my rack (It was a couple of upgrades ago), so any cheap tweaks while I save for a good rack are worth a try.
Can you confirm how you actually placed these tiles on the rack. Are they just sitting on the shelf with the amps sat directly on top?
I think we both realise that if we invested in good racks we would'nt be trying these mad things, but in the meantime, as I'm popping into town tomorrow, I might just stop by Woolies.

Ade
PS
Does anyone know what a 6 shelf Mana/Hutter costs?

Posted on: 17 December 2000 by glenda
The marble is located under all my bits (oo er missus) ie cd , pre / power amp & speakers .I would post you a slab of marble but it would cost more to post than purchase . Just do it !!!!Cheers.

Thanks

Vuk,

Thanks for that, looks like I'm nipping down to Woolies.

Later that day.......
I bought three of these slabs (£7.98) and it looks like my wife has got some new additions to the kitchen.
I placed them under 72/hi/140 and although I could detect some improvement in bass definition, this did not make up for the fact that something had been lost. It was like some of the life had been taken away and the music did not seem as 'emotional' as before. It may be that they took away something that should'nt be there, but it's obviously something I'm used to and prefer.

I'm not saying it won't work, it obviously has for you, Tony, but not for me. In fairness, you said your rack had wooden shelves, and mine are glass, so that might be something to do with it.

Still, the wife's now gonna have something else to open Christmas morning.

(Shuffling my gear around to try this, I'd forgotten how deceptively heavy Hi-Caps are. Is lifting a Supercap a two man job?)

Lerxxt,

If I've followed this correctly, you've gone from 82/2*Flatcaps/180 on Mana to basically a Nait1 on Quadraspire. And Dave confirms that its sounding better than previously (hope thats right).

Could you explain why you havn't (or didn't) just move your 82/180 system onto Quadraspire ?

To me, a basic "rock-solid" Naim amp is the 102/180 combo, but you seem to have lowered the goal-posts even further.

Dave-

You said: "I have yet to meet a Mana user who
has the first idea of the fundamentals of what
it is that makes music work"

I can't tell you how much freedom you've
given me personally with this enlightening view.
All the time I've spent over the years; money
spent on a Conservatory degree, lessons, concerts;
and well, Mana, a P9 and an xx-1 and I still
don't understand why I'm moved by both Eric
Dolphy and Maria Callas. I can just plain
stop trying to figure it out! I CAN'T figure
it out! I use Mana! Whew. Life IS much simpler
now.:-)


Happy holidays,
Scott

Interested in that you are thiking of doing a comparison between QS and Isoblue with kit loaned from Griffin Audio - Birmingham UK.

Let us know the findings.

And anyone else out there who has been fortunate enought to compare QS-Isoblue-Mana-Hutter.

Ade: please give my regards to Bob Griffin at Griffin Audio as he and Dave? Hanna 1st introduced me to real Hi-Fi at Griffin Audio. I was walking down Bristol St. to Ritcher Sounds to buy some new speakers. I walked passed their Griffin Audio shop and thought I would call in (I think it only had an LP12 in the window in those days. Needless to say I was hooked (this was back in the 1980's) and ended up buying my 1st real system from them (LP12, EKOS, K18, NAC72, NAP120). I moved away from Birmigham in the early 1990's and now get expert support and guidance from another specialist shop like Griffen - namely the Sound Organisation in York.

Regards

Richard
