Do stands make a difference for equipment?

Just noticed that way back near the beginning of this thread, Elizabeth, who is normally sensible and well informed offered the opinion that high quality racks make nearly no difference. That is definitely not so Elizabeth. It is as important for amps and digital components as it is for turntables. If you disagree, it is because it has not been demonstrated to you in your own system.
I recently started using a Starsound Apprentice rack beneath my transport on an Adona rack already, and the difference is easily noticeable.

After years of this I have happily ended up with Sound Anchor stands under everything, that are spiked with either Eden Sound Bear Paws (speakers and component rack) or Audiopoints (amp stands and subwoofer). These provide very solid support and hard to beat build quality.

Just joking, I love ya' :)

Stands, vibration control,etc. are tuning devices. They may alter the sound, but whether for better or worse is entirely a matter of taste and what the system may need. I use several Symposium products and like what they do IN MY SYSTEM. I use Ultras under the amps (sitting on the floor between my speakers) and my preamp and Svelte Shelves under my speakers. However, they make little or no difference when I tried them under my CD player (I have been too lazy to experiment now that the CD player has been replaced by a music server).

When the Ultras were tried under an Audio Aero Capitole CD player in a dealer's system, the result was decisively negative--the sound became too lean and sterile sounding. This is all a matter on tuning, there is no "more" is better or "less" is better answer to what one should do.
