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.

Albertporter, I finally got around to reading your post again and thinking about it. I think I understand what you said. I interpret your answer as saying that with so many variables at play we ought to attack the problem by observation followed by deductive reasoning ie. learn from listening to components and tweaks for what they do and then deduce the impact it might have on another system. I often get a bit riled when I see too much inductive reasoning of the kind "if all amps measure flat then they must sound the same, so if you hear a difference it has to be a placebo effect". I am very impressed with the AC power work you have done. I thought my efforts were obsessive, but are clearly the work of an amateur. Your own transformer - I will look into that one further.
To Albert Porter: could you provide an internet address to read details on star grounding? Or could you describe briefly it´s basics. Thanks
I am not going to respond to emotional insistence of being correct with folks who essentially say "I know its good when I hear it". What is being said here? I'm right, you're wrong" Quite a strong debate! Ah-ummm
Noel, can you hear the 15.6 kHz sweep of a CRT tv, or are you too emotional? I can hear mine from the other end of my house (It measured only 74 dB right against the back of the tv, with my spl meter...must be less than 15 dB when I'm hearing it around corners, and down hallways). I'm not concerned about what you think, because you're not an audiophile, but an agnostic who can't hear jack. IF THE GENTLEMEN ON HERE RELATE WHAT THEY HEAR WHEN COMPARING AMP STANDS, WHO ARE YOU TO TELL THEM THEY AREN'T HEARING IT? Some of us on here can hear very well, and I have no doubt that you have lost most of your sensitivity. It'd be like a legally blind person working at a movie theater, never being able to properly focus all of his movies, and cheating patrons out of the cost of admission...
