Agree with the earlier sentiments. Assuming you have found a stereo amp you already like, if you upgrade the set-up to mono w/the same type amps...prepare yourself for even more music.
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.
