A local friend of mine had either the DR-2 or DR-3 I don't remember which one. I think it was 25 wpc? Anyway, it is probably the best sounding amp I have heard or one of the top 2. These amps sound wonderful and I told my friend to keep it and never sell it...lol. Of course he did because he has huge inefficient speakers. Highly recommend these amps if you can find one.
