How important is a good rack?

I know what you mean by not wishing to put the things on the floor. Everyone is like that. But when you go to the shows many of the best sounding rooms have the equipment on the, uh, you guessed it. The floor. It's easier to control what's going on.

10 yrs ago I was using a generic Sound Organization rack and came across a used Billy Bags rack. The only reason I pulled the trigger was the price ($600. The rack cost twice that new!) and I liked the look of the rack. I wasn't considering sonics at all, I didn't think it would make much of a difference. I was wrong. I immediately heard an overall improvement, everything was the same as before except for the rack so....not sure if Billy Bags is still in business but if you can find one 2nd hand I highly recommend them. As far as my TT's concerned, I ordered my Linn LP12 and bought an Italian custom made stand (low mass, high rigidity, low to the ground, spikes on top and bottom). This was 25 yrs ago and haven't felt any need or urges to change anything!

Symposium ISIS is another unfortunate name for a product.

LOL! (Did Symposium choose the name before ISIS chose theirs? ;^)

There are even worse names in the audio industry though, Schiit for example?
For their sake you always hoped it wasn't... :)

In the last 15 years I saw nearly everything and to make a long story short, when it is solid made, it is ok. Anything more is depending on your wallet. Most of the expensive supports are very overpriced and the advantage in mainly in the belief of the customer....the best investment is in better electronics. Btw. I met Audiophiles who own very expensive racks AND they place their units on a additional shelf PLUS cones PLUS another shelf (sorry, replace the word shelf with isolation device) and on top of that triple they have the unit. Even a triple for SUT's... I bet my car, when the space would be higher they would use 5 devices below a unit.
And, now the ultimate question:
Did it change the "sound" from awful to heavenly?
Hm, all I can say, not for me. But, it is a nice addition and it looks definitely very serious :-)
