I've heard it. It's by far the best server you can get right now and he keeps upgrading to lower jitter even more. I love the QX5. The thing is that he's building a brand new DAC using what he's learned from other DAC's etc... I don't know if it will be better than the Ayre, so for now, I'm keeping the QX5. As I posted above, I won't make a change there until I know it's a better DAC, lol.
It can get pricey, but if someone has interest, they can get in touch with me as there are often ways to get them for less like anything else. Folks just need to ask, lol.

I was told by a few to get the LS28. What are the used price differences between the two? Shouldn't ARC be coming out with new pre's soon? Maybe if there is a new model soon, I can find a nice used 28, lol.... I think their preamps are their best products. I always love them.
