Lansche plasma guy Posted August 27 Share Posted August 27 I used to own the matching Macassar ebony Slagle Autoformer pre (the better Slagle with the flying leads). The Macassar is real solid Macassar not a veneer and looked beautiful in the flesh. These will be great amps. LPG 1 Link to comment Share on other sites More sharing options...
Ihearmusic Posted August 27 Share Posted August 27 I had the pleasure to listen to them hooked up to efficient full range speaker and I was blown away by how musical they are. Firm lows and just beautiful mid range. They would not disappoint that is for sure. 1 Link to comment Share on other sites More sharing options...
