I have monoblocks though it’s due to sound performance per dollar. There are excellent stereo amps and crappy monoblocks.
If you can audition - I recommend it.
Stereo or monoblocks
I recently bought a pair of the JBL HDI-3800 speakers. I also own a McIntosh C-2300 preamp. Should I buy a used McIntosh mc402 stereo power amp or try to find a pair of a different brands monoblocks? The new Schiit Tyr has my interest.
