Is it best to isolate??

Very nice, Buconero117. Thanks!
I have found great success isolating with Symposium Rollerblocks. The effect is clearly noticeable. The sets come with three blocks and three steel balls, with the option to upgrade to tungsten balls. Some people double the blocks, putting one on top of the balls upside down. The additional blocks upside down and the tungsten ball upgrade make a difference to my ears, but YMMV.

The appeal of isolation is that it is not that hard or expensive to accomplish and can only help, not hurt. So it is worth tending to. Throwing mega dollars at esoteric technical solutions often marketed it is of marginal value IMHO because it is not rocket science to physically isolate devices. Isolation against nearby electric or magnetic fields is very important, especially for low level devices, like phono step-up devices or pre-amps, and can be a bit trickier to deal with, but straight forward cost effective solutions (like mu metal) are available for that as well.

total isolation I quess would be to put the components in another room away from the speakers..Since this is not practicle what do most of you guys use under a cd player to maximize sound?I own the Pass labs x600s and the x1 preamp..For the amp I had some 2" thick granite cut to size for the amp stands and I'm not too sure this was the best thing after reading some things on this site..As for the x-1 it's on my rack,the power supply feet are on 4 metal tubing pieces cut to about a 1"1/2 thick and filled with lead..The control unit is resting on 3 brass cones with the cones in the disc filled with lead..Alot of people say that using granite makes the sound sterile or dry.Has anyone had any experience with this in there equipement??

You can't isolate anything with titanium bearing or any other bearing for that matter!

yes but will it sound better.Theres so many times I wondered in our effort for the holy grail if we might be making it worse...
