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.

re mg123: I think that for most construction the floor makes the most difference. If you have high end speakers with good bass extension, the floors and the walls first act as passive re-radiators and of course the floor vibrates the equipments. My house was built in 1935 and my listening room was designed as a large (about 7000 cu ft) music room. The walls are double thick stucco exterior with heavy plaster interior so they don't vibrate much. The floor joists are full 2x10 on 10 inch centers with a center support wall in the basement. This was to support the weight of a full sized grand piano and a room full of people. The floor is oak and the subfloor 3/4. This is much stronger than modern construction. However, when I put basement floor jacks below the speakers and the equipment stands, the measured bass response changed. (Impulse and MLSSA). Even then I use amp stands (zoethicus)and they make a difference. However I have tube amps. Getting your floor stiffened is the first step. Also the air pressure induced vibration is something to consider. Just lightly touch the largest panel on each piece of your equipment during a loud bass heavy passage to feel how much mechanical energy is transferred. I use bags of lead shot, 50-75 lbs per amp, preamp, dac and transport. It has made a huge difference.

Just for the record I have no idea who Carl_eber is and even if I did is there any reason to respond in so insecure a fashion. How does acting lack an emotional reactionary help your case. Believe in your intellectual arguments not your emotional defences. I will not respond to emotional arguments. Stereophile has a vested interest in not believing in double blind tests, even though I don't know if they not believe in them as a group, because you can say anything (i.e., anything) and no one can challenge you. Kind of great job security.

Nanderson; Carl is one of the "good guys". And you may have just touched on the main nerve of this whole issue: music has emotion at its very core. Whereas blind testing is logical, intellectual, and cold. Of course there is a place for both (a very narrow place for blind tests), but when I listen to music for enjoyment, which is almost all the time, I listen for its emotional content, and for the way it "moves" me. you just can't capture those things in blind test listening, IMHO. And when kept in proper perspective (and I decide what that perspective is), I also enjoy Stereophile magazine.

I enjoy Stereophile Magazine myself, Garfish. Emotion seems to have taken on two different definitions, however, in this case. Somewhat like the difference between a soccer mob upset because their team is in jepordy of losing a game and rather than seeing how is the best team that day they attach the opposing team. That really does not decide anything except that the crowd is not mature. Musical emotion should carry you into another world but not discussions about silicon and machine screws.
