    It is a mono block in function. You will require two to handle a pair of speakers. Unfortunately there are several brands of speakers that cannot be bi-amped (or bi-wired).

    I look forwarding to hearing this one.

    Shouldn't it have two AC cords?

    A light bulb comes on, I thought it was tubes feeding SS like a hybrid but it's actually two amps with tubes for mid/high and SS for bass and Dan mentioned the crossover. Now, this is even more interesting.

    Thank you Dan. Certainly an impressive feature set. I bet these are wonderful amps. SS for the bass and tubes for the treble, wow!

    It's a long/short story. The short version is...I changed my mind. The long version is too long to discuss here. Could also run afoul of forum rules. Let's just say I really like the Pass sonic personality. It was all my decision. I auditioned the Pass int 60 and really liked it, especially with the MSB Discrete with optional second power supply. But I thought I might want just a little more headroom so I went with the int 250. Can't wait to hear it in my home listening room.

    This amp looks like a steam train ... kind of weird. I bet many will miss the gigantic meter present on the 611 / 1.25kW.

    Re: McIntosh 901

    Is this a one off prototype, something old or something brand new? And, no, I don't want to buy one...too big and heavy for my application. Plus, I've become a Pass fanboy.

    Re: McIntosh 901

    Brand new, regular production amp. Think of it as a MC601 (for bass) and MC2301 (mids/tweeter) in one chassis with crossover or direct inputs and adjustable gain levels.

    Home run I’d say!
