Integrated tube amp for Coincident Super Eclipse

What price range are you looking at?

Personally, I'd go for a vintage Fisher x101 or a scott 299 or Pilot 240.

What amp do you have now. I assume you own the coincidents. The current amp you have will cost you knowthing. If you like it and there is no fortunes invested in it keep it.
From your preferences including Rock I think an SET will not make you happy no matter if the Coincidents are 99 Db sensitive and over 10 ohm.
OTOH the expensive investment you need to recover by selling the current amp, may end with a net loss. Especially buying a new one to replace it - even a used but new to you amp.
I haven't heard these since they had gotten to 20 watts but the "Wave 25" ASL amps are only a few hundred a piece. It kind of odd I hear nothing about the ASL products of late. Anyway Isreal Blume has an ASL 300B amp the Frankenstein I believe modifed for him. There may be synergy between the two product lines.
I second the bang for your buck in using an older amp. Mac recievers if old are about $500 but you get the preamp free. So called vintage amps even fully refurbed can be had for $500 or less as a rule . If running but needing recapping less than $300 easy. If broken don't bother.

Thanks for the responses...I am using a NAD 325BEE. Packed up my Quad 909/99 to sell next month. Don't need the power. The NAD sounds pretty good but just curious about using a tube integrated with these speakers. Looking at no more than $1250.00 for a used integrated amp.

I have the same speakers and am using them in a 14X24 room. I used to use 8 watt SET amps and those worked great, but, per the previous suggestion, I'd choose a different amp for rock (I don't listen to much). Currently using a Modwright KWA 150 which is a great match, but probably not what you're looking for as it's not integrated and out of your pricepoint. Integrates at the $1K point I'd consider worth auditioning that would excel in rock and still sound great in your other preferred genres: Portal Panache, Rega Mira III, Audio Refinement, Creek 5350SE.
