Pete, you simply have one of the most beautiful Mac systems I have seen. I paid 3K each for my three new AS125 Mac amp stands. I think yours just as beautiful. I care zero about vinyl. If I were going that route it would be with a high quality reel to reel deck, but that turntable and arm is something else to behold. It's beautiful, a work of art. I know it sounds great but I have no patience for vinyl. The way Mac's are designed with their simple feet allow for these types of upgrades like the Stillpoints, which I have no doubt significantly/tremendously improved your sound. Stillpoints work really well with McIntosh, I think.

Wilson is soon coming out, next 3-6 months, with Heavy Duty Pedestals desighned for amps. I'll be placing 4 under each of my 3500MKII's soon after. I agree with you that isolation devices, well designed like Stillpoints are, greatly improve the sonics of any system. If there is such a thing as audio crack isolation devices like Stillpoints work and the only damage they do is not to the body but to the wallet, soon forgotten when you discover the beautiful sound flowing from your speakers.

Well done!

Best

Charles
