I had a 20yr old stratos mono amps, they would lose power when throttled on power hungry speakers.
BUT, at moderate volume, and critical listening, they were frigging amazing, the highs, lows, mids, were all balanced, thin Lizzy, Gary Moore, Uriah heep, motorhead, mercyful fate, diamond head, spartan warrior, tank, ......even Kreator, accept, Sodom, flotsam & jetsam, venom, onslaught, Hirax, Satan jokers, ADX, ETC ETC,
We’re powerful and the soundstage was full and very enjoyable.
I’m so looking forward to my upgraded stratos to Kismet+ mono block maps.
Stoked!
