Absolute top tier DAC for standard res Redbook CD

Toetap - I lied. I do know the CenterStage. They are not actually from Pitch Perfect, they are from Critical Mass racks distributed exclusively by Pitch Perfect. They are a footer version of their constrained layer damping shelf technology. As such, I have no doubt whatsoever that they will be effective. HOWEVER, like the Qpods I question the efficacy of the constrained layer damping technology in a footer, since the physical size of th footer may simply not be enough mass to truly allow any statistically significant amount of damping to occur. The Qpods clearly work but I found them (although my jury is still out) to not be 100% even across the full frequency spectrum. I attributed that to the limited size of the footer. Now Critical Mass is the premier leader in the field, so if anyone is going to do a constrained layer damping footer right, it’s them! I would need to hear them to give them my formal support. 

I have officially decided to go with Symposium so I don’t need CLD footers on my shelves and my footers need to conduct that energy to the shelves to be properly managed. A similar size/shape top level CM shelf would be 3X more expensive. 

Hope that helped. 

Yes, thanks. That was a good summary. The mystery is that users report that the CS footers take a while to “burn in”, up to 7/10 days apparently and before that point, they sound terrible. Sounds like some sort of annealing process going on due to the vibrations passing through? 

I have the IsoAcoustic Orea’s Indigos on test at the moment. They work really well and considering their cost they are a great starting point. I’m sure the Symposium will be a step up though, but with shipping costs from US it will be a much more expensive set up.

 I’m also talking to Stacore in Poland about their shelf’s. I’m in touch with someone who really likes Symposium and who has gone over to Stacore. He currently uses both. It’s seriously expensive though and weighs 100kg. Something I’m going to explore in the longer term.

Critical Mass says the same of their shelves. I think it has to do with the viscoelastic material compressing to its fully compressed state over a few days before it achieves proper thickness to effectively distribute heat. As I have said, I believe CM is on the cutting edge of shelf and rack design, the best in the industry. But you pay for that!!! And I am not convinced that for the same money that you can get the CS footers, you can probably get the same or better performance from a less expensive Symposium Ultra shelf. But until I hear that I can’t say for sure.

Yes, the Orea and Gaia are ridiculous value for the money. Nothing comes close for that price.

The Stacore looks interesting. But at almost 100kg and not available in the US it’s not on the table, so to speak.

PS - My Giant Diamond Resonator ShunMook footers have arrived. I haven’t had a chance to do anything but look at them. They sure are nice to look at though. Eval to come.

In the event you decide you don’t like the Shun Mook jobbers I’m an instant buyer. 😎 Oh, by the way, you guys can keep all that other stuff, just gimme a Minus K and the Shun Mooks to put under it. 🤡

@geoffkait, I know somebody in the U.K. who recently had both the Minus K and Stacore side by side in his system for evaluation. The long and short is that he thought the Stacore worked better in his system and he now has four. Active vs passive systems, he preferred the passive solution. He uses and still recommends Symposium before he moved on to a “different level” with Stacore. I believe he uses Symposium couplers with the Stacore. However they weigh 100kg and the cost of one is equivalent to 5 Ultras and RB’s. So it’s a serious investment. Build quality I’m told is excellent.
