I'd agree with @jimcrane in considering Wyred 4 Sound integrateds; they can probably be a bit speaker dependent but seem very clean and powerful.
I've used an STI-1000 for years and think it still a good match for a pair of Raidho D2 speakers (even if it's under-priced compared to spkrs). A too warm amp might not be as good with Raidhos.
I am very interested in Devialet and Rowland amps on the Raidhos. I used to see/hear Rowland/Raidho at shows and loved the pairing. Many seem to love the Devialet products. I'd love a listen before parting with too much money since the W4S satisfies me, even if I know better exists.
