A few good responses from this A’gon Nov ’21 thread, same related Ascend Tower with the larger RAAL tweeter. Lower watt SS amps noted, and some notable tube amps mentioned if you dig through it.
Ascend Acoustics Sierra Towers with tube or lower watt amps
If anyone has had experience with Ascend Acoustics Sierra Towers — RAAL tweeter or not — I'm curious about your experience with
(a) tube amps and/or
(b) lower watt solid state Class A amps, such as the Pass XA-25.
Any details you'd care to relate are welcome, and thank you.
