I have had triamplified DIY horns in my main system for the last nineteen years. I initially used a tube/SS hybrid amp on the bass and Cary Audio 2a3 SET monoblocks on the mids and highs. I ended up with a Pass Labs X150 on the bass and two First Watt F3 stereo amps on the mids and highs. The change from tubes to SS improved the SQ and is quieter.
