Raidho D1's and recommendations for amplifiers

I've owned Raidho C1 and D1 and now have the D2.  The D1s like power.  In most cases, fast powerful (at least 100 watts, preferably 200 watts) solid state amps are preferred, but there are some rare high power tube amps that do work very well with these speakers as well. According to one dealer I trust, he doesn't like warm sounding solid state amps and tube amps with the Raidhos, as the speakers already have a slightly warm sound in the lower midrange and upper bass. So tube amps like VAC or most ARC, which IME don't have very good bass contro, may not work well.  However, for some reason switching amps from ARC and NAD seem to do very well according to the dealer. I've used high powered tube amp with these and like it very much, but my tube amp isn't particularly warm like McIntosh for example.  However, they do require a tube amp that can control the woofer with authority.  Raidho seems to like Solution and Constellation amps, but I think those amps are way overpriced.  I've heard the D1s with Rowland amps, which are very smooth sounding with D1s, but IMO lacks some liveliness.  I would agree the 75 watt Coincident amps would not have enough power for the D1s.

Right! I agree with you...
The very best amplifier I have tried with my D1.1 was the Fm acoustics 811/255 combo, but even with my darTZeel CTH 8550 integrated I am totally happy...!!!

@kin You have D1.1's? Did you compare them them to the D1's? If so what differences in SQ are there?

I am in the market for speakers and have pretty much settled in on the Raidho D1.1s they are fantastic! Heard the d1s last year but couldn't pul the trigger they are at T.H.E. SHOW 2016 going on now in Irvine Califonia the Aavik U300 is great but yeah it's $30 large a big chunk however it is an integrated amp with phon stage and a DAC so altogether that is more bearable talking to Lars they do like power 100W + and they seem to feel class D like the Aavik solid state is a better fit....

@qbndds - What amp do you have now? BTW the D1.1's sound a lot better than the original D1's so I would say it was a good thing you couldn't pull the trigger last year. Otherwise you would be looking at getting them upgraded.

Anyhow back to the amp. When I had D1's I had an Octave V110 tube integrated w/black box and it sounded great. Then I upgraded to the D2's. Only at very high listening levels did the Octave fall apart (mids and highs would increase in volume but the lows stayed the same). I think that was more of a tube characteristic so after the Axpona 2015 show I bought the Aavik U300. I think you should listen to the D1.1's with your current amp first  Then audition different amps to get the sound you're looking for. If you like the Aavik check out Jeff Rowland and Soulution. Burmester is also very good and a little warmer sounding.

Good Luck
