Best Intergrated Amp for JMR Twin Sigs under $500?


Any suggestions for a used integrated amp that will match well with JM Reynaud Twin Signature speakers (91dB/1W1m,4 ohms)?

I feel like maybe my current setup is not realizing their full potential.

Ive tried (in order of preference):
1. Cyrus 2 integrated
2. ASL Wave 8s
3. B&K ST-140

Power amps were used with preamp section of Advent 300 or NAD 3020.

Budget is $500, room is small, listen at low to mid volume.

Thanks.

It's worth waiting and saving to bump up your budget a bit. Those speakers can do justice to a much better amp than those you list, and their strength is in the mids. I would look for a used tube amp. If you were lucky you'd find an Audio Space AS-3i ( about $1500 new ) but they are very rare indeed on the used market. The Rogue Cronus would be another in the same range but with a different sound. You might think of Jolida, at a lower price, if you can't find the others.
Thanks. I could stretch to $1k. I've heard good things about the brands you mention.

I wonder if the Miniwatt N3 that everyone is raving about would work?

I've also read good things about Cayin and Vista Audio.
Exposure 2010S. Bit over your budget, but a very nice piece. The Cyrus and ASL will work well also.
