Robert Brook has a blog which he calls
A GUIDE FOR THE DEDICATED ANALOG AUDIOPHILE
Below is a review Robert Brook wrote for one of our favorite tweaks. We have most — but not all — of our equipment sitting on one of these stands. We were big fans of the earlier model all the way back in the early 2000s, the kind that had three air bladders inside for isolation. You had to pump air into with a bicycle pump.
Those Cursed Bladders
The unfortunate aspect of that design was the fact that the amount of air in the bladders had a profound effect on the sound quality of the system. We would pump the thing up, and then listen, and if the sound wasn’t right we would let some air out. We would do this a couple of times, and if the sound refused to get better, we would pump the thing up and start the process all over again.
For every shootout.
The air pressure changed during the day with the heat, and the bladders did not hold air all that well, so you had to do a lot of pumping and air releasing if you wanted to get the best sound.
Crazy, huh? And that’s in combination with all the VTA adjustments that were needed for each title.
