    The NS-1000M sounds fantastic with V-FET and MOSFET amps. The B-2 is a VFET amp, and a very good one at that.
    I have the NS-1000M and I have been driving it with a V-FET power amp for close to a decade now. I tried other amps using valves or bipolar transistors, but they never sounded anywhere as good as my V-FET amp. The depth of the bass, soundstage, and clarity with V-FET is my type of sound. I would go for that Yamaha myself if I was looking for a new amp to drive my NS-1000M.

    Nope, not heard. Seriously sexy, though!
    Mid 70s - will have needed TLC and a thorough service.

    ... "it IS one of the best amplifiers of all time "

    The NS1000M speakers started 1974, so same period as the amp.
    Whether or not they were designed to work together I have no idea, but I wouldn't be surprised.

    Go on, get it, you know you want to.

    Bear in mind that VFET amps like these and the Sonys are a gamble. As far as I'm aware, VFET's are now unobtainable, so if it goes 'pop', you've had it!
    It is impossible for anything digital to sound analogue, because it isn't analogue!

    It entirely depends on the amp itself. I needed a bucking transformer for the Sony as the UK voltage was too high in my area for the tolerance of the Capacitors inside. Personally, I'd suggest being prepared for extra spend to ensure it is made safe.

    This is from experience.
