Lowther Speaker Amp Recommendations

Definitely Decware. I had Lowther MkII Big Ports and have now switched to Decware HDT's. I use the Decware Signature Mono's. (SV83S) Super amps. Detailed, spacious, dynamic, inner-detail. They are amazing amps. You can actually use the SE84C-S and have exactly what I believe you're looking for.

I have Sun Audio 2a3 driving Lowther PM6A in Voigt Pipe (Twl Mod.) and they work wonder.

I had the Berning MicroZotl(headphone amp) with my Lowthers, and I found it to be a wonderful sounding amp, but just a little too weak to get the volume levels that I wanted in my large room. I have since moved up to another Berning SET ZOTL amp which is superb.

Depending on the model of Lowther driver, and the efficiency level, you should be able to get a nice SET amp like a 2A3 or 300B to work very well with your speakers.
