Back in the 1990s I was using a Naim based system 72/Hicap/250, and decided to try a pair of Naim’s 135 monoblocks (based on the 250). The differences were noticeable immediately. The Naim house sound remained but all sonic aspects improved. Most notably, separation. The 135s also had better control of the bass, improved sound staging: depth, width, layering of instruments. In other words, everything that I liked about the 250 and more.
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.
