I don't see a how the stand could make much of a difference except for digital gear. I had my classe amp on a cheap wood rack for awhile and it sounded great. When I bought my metal rack it didn't sound any better. I am glad I bought it though it really finishes off my whole system. And really the music is more involving because everything around where the soundstage is is more pleasing to the eye................................I sure hope your not running those amps through all that line conditioning either. They really restict an amps power flow and can really dull the sound. Especially with the higher watt aleph 2's. The 3 has such a low watt output that it is probably not effected as much. After a lot of experimenting I plug my amp straight into the wall and only use two MIT Z cord 2's for my front end. Thats it. I have a passive preamp so there can be no power corruption for that.
