Ayre gear is the real deal. I'm convinced that fully solid state is the way to go from now on.
I have read that the Ayre amps are very good but if you use both their amps and preamps that may be too harsh a sound for some.
I use a K-5xeMP and it is super. It is very revealing and if you are not careful I can see where lesser components around it could make it sound harsh - cabling, dac, amp. But right now I love the clean bass it delivers, beautiful soundstage, and effortless delivery.
My amp is a Wells Inamorata and I am looking for a D'Agostino to replace it.
