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.

Iceraven, excellent pointer you gave! Solid advice and a good starting point for anyone.
My PhD work is in the field of prob testing. I suggest anyone that is willing to be humilated try a double blind test. A wordy explanation does nothing but convince the less sophisticated that you must be right since you devoted such good grammer and time to your explanation. I have sent every audiophile home with their tail between their legs on things they think they hear. I find this fun helping people save money for retirement and time with their family. Good luck but lets get back to reality.
Nanderson, perhaps you live close enough to me to listen at my place. I can assure you that if you have not ever heard benefit from stands or other forms of isolation under amps, then you have an interesting experience ahead of you. In fact if you really believe your statement, and it is the result of testing on a sound system, then you have never heard a high quality system. In my system (and I believe, most other posters at this site) it is absolutely no problem to hear the difference between various materials, such as spikes, and in addition, there are several layers that can be inserted, I.E.: (Starting top to bottom) (1) Amp, (2) feet, (3) stand, (4) feet, (5) floor. In the text where I have inserted "feet" the material can be any one or multiples of the following: wood, carbon fiber, Sorbothane (Audioquest) Soft Shoes (McCormack), Delrin (Simply Physics), Valid Points (Walker), stainless steel spikes (various), air bladders (various), sand bags and/or sand trays, etc. ALL of these products sound different. Mind you, I would not argue about the outcome of testing these individual pieces in a system, because depending on the equipment involved, the construction of the floor, personal taste, etc., arguments would break out about which one is the winner. In any case, there is indeed a HUGE difference in stands and other coupling/ decoupling devices. The question is NOT whether these devices work or not, this is not an issue! The question is, which device works in the particular system that is being improved upon.
Albertporter send me an e-mail and we can discuss a double blind test. Please understand I don't have an axe to grind except to blow the smoke from the obvious nonsense. I have been involved with hi-end audio for 3 decades. My equipment I listen to and when I visit others starts in the Levinson, Krell, Audio Research, Magnan etc league. I don't want to get emotional (defensive) about this so I won't add more to that. I always love the double blind test with those who scream out, insist that they are right. We'll see. It is most important in all things in life to be honest to ones self and others. Double blind testing does that.
I bet Nanderson and all doubters are listening in dirty living rooms. All the junk laying around is enough to distract their attention form the improvement that the amp stand is giving to them
