I also have Esoteric SA-50 and I join Krell-man in his recommendation of Spectron amp. The best I ever had. Period. Better then Pass, BAT etc (I never liked Krell that much). For $5k (they have Holiday promotion now) you can have great amplifier - extraordinarely musical and involving. Plus your speakers (similarely to mine B&W 802 Diamond) need lots of power and Simon from Spectron has planar speakers similar to yours and Spectron is one of the most powerful amps on the market today.
Shindo is good preamp but I have Joule-Electra. I bought because it was (partially) voiced on Simon's system with my Spectron and synergy is simply extraordinary!
Plus, Harry Pearson awarded this preamp "2010 HP Editor Choice" Award noting that it is most romantic preamplifier (obviously he did not mean to say that its euphonic but "grabbing" you). This preamp is the last in my life !!!
All The Best in Your Quest !
