What is the best SS Amp and Pre given the trends?


I currently have an active Linn system (Klouts, Kairn, Kabers) and want to upgrade. I originally chose Linn because of it being more musical verses sterile sounding and it's small foot print. In looking at upgrade choices, I've been surprised about how the once frowned upon Class D amps are suddenly getting noticed (Nuforce, Channel Island, Bel Canto). I'd like to get better sound stage, image, power capability, and detail without harshness or having to going the tube route. I've read mixed reviews on the Ayre MX-R's, so I'd appreciate forum members thoughts on current market choices and considerations for putting together a new system.

While the 'best' of anything likely does not exist, the musically most satisfying amp I have auditioned this far, regardless of underlying technology, is the new Rowland 312. See my further comments on this device at:

Please note that there exists a vast sonic difference between the 312 and the lesser Rowland 501 and 201 monoblocks. The significant price difference is in my own view fully justified.
My favorite SS pairing so far has been the
Ayre K-1XE/Ayre MX-R followed by the,
Pass Labs XO-2/Pass Labs 350.5
I just demoed the Ayre MX-R connected to a Shindo tubed pre amp, Esoteric 03, Wilson Maxx II's, and Siltech cables/inter-connects. Sounded unbelievable!
I should like to add that the Rowland 312 I heard was matched to a Rowland Concerto pre-amp. I was truly stunned by how good the combination sounded. Had I known this fact one year ago, when I was still on the market for a pre, I would certainly have performed an a/b comparison of the little Concerto against the admittedly marvellous ARC Ref 3, which I eventually purchased.
if price is not an issue there are a few others to consider.

Burmeister, Goldmund, MBL and FM Acousitics all make ss preamps and amps that are highly respected if very expensive.

my personal favorite and the best i have heard is the darTZeel NHB-108 ss stereo amp and the NHB-18NS battery powered full function preamp.
