Pass 250.5 vs. Marantz SM-11S1 Amps in Mono


Anyone used both these amps? I have loved the Pass 250.5, but have the opportunity to get a pair of the Marantz (reviewed in Stereophile back in 2008), and had a quite good review, just as a stereo amp. They have a mono switch to run two of them, which would output something like the Pass.

Two totally different designs. The one thing the reviewer said was the attack and decay were excellent, better than his Musical Fidelity kW (1,000 w.), but that they couldn't hold on to the main sustain of the notes as long.

The Pass is a great amp, but has its own sound, as any amp does, and runs quite hot, bothersome in the summer.

I'd be using them with Dali Helicon 800 Mk.2 and Aesthetix Calypso.
