of course they make a difference.better bass definition and clarity.every frequency will sound clearer more refined.i've experimented with [nad-b&k-aragon-levinson-audio research-vtl] all of these components and the difference was substancial on all. the type of stand used is critical to the amount of benifit achieved.double mdf with good polycrystal spikes works better than most of the stands mentioned above.the polycrystal amp stand is excellent 300.00 and the zoethecus is a little better 600.00 .i can't beleive people state they don't hear any difference[blind-standing on their head or any other way] maybe they can't perceive a change,so they won't even try one.if you have these amps on the carpet,put them on stands and you'll truly see for yourself.
Amp stands- Do they work?
I recently purchased a Pass Aleph 3 and loved it so much that I "had to buy" a pair of the Aleph 2 monoblocks. I have been A/B-ing them at my home for the last 3 weeks for most of my free time. The 2s have a lot more presence, but lack the for lack of better words "musical reality" the 3 has. Forgive me for the term, but if you've heard the 3, then you probably understand. Anyway, I have asked most of the guys at Pass Labs and they essentially tell me I am hearing things- that the 2s "have all the sonic characteristics of the 3, just more of it" I have eliminated all other variables except that the 3 is on the bottom of my rack (Salamander Archetype), and the 2's are on the carpet in front of my system. I am interested in anyone's input as to the impact a reasonable stand might have on the sonics of my amps. I currently am acting on this hypothesis and have put the 3 on the floor next to the 2's. If it is of any help the components are in order- my source is a Muse Model 5 transport, Illuminati D-60 digital, EAD 7000 MkIII D/A, Kimber KCAG, Muse Model 3 preamp, WBT 5151 -great cable!!!!!, Pass Amps, Nordost Red Dawn speaker cable, B&W 804s. Counterpoint PAC-5 conditioner, API Power Wedge 4A conditioner. Marigo RMX ref power cables. Amps are using stock power cables- Nelson Pass's recommendation. Thanks for listening and I look forward to any input.
