Honestly, the mono vs stereo discussion has never really shown a clear winner. They’re good stereo designs and good mono designs. It will all come down to the particular implementation you are looking at. I have used both and the only advantage that I see in the mono is placement feasibility. The McIntosh MC402 is close to a dual mono design if that’s any consolation and is a great option, reasonably priced on the second hand market. You can’t go wrong with it. I am not familiar with the Schiit Tyr but it was reviewed favorably in Stereophile magazine and is even less expensive. So either you will have a good amp to match your speakers. Give both a listen if you can.
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.
