    I like the fact that the Yamaha is 'defiantly' louder. ;)

    I remember auditioning the 801's powered though some Yamaha separates when they first came out. They reproduced some of the most accurate sweet music from the bottom end through to the top.

    Hello everyone,I think it's an input problem, because I've run my 6 Cerwin Vega's on my Yamaha MX-1000u which is basically the same amp you have, and the amp handle it without a problem.
    The MX-1000 is new amp to my setup, so I hooked all my speakers to it and it filled the room completely.

    I suspected gain - good to see this is the problem. Consider the typical phone's earphone jack to be a terrible source to evaluate audio equipment. Connect a CD player to the Tandberg (using it as a pre for the M-85) and you should be able to crank those CVs no problem-o.

    I've been on vacation since my last post returned and actually had time to hook up and appreciate my new MX 1000U, now I personally know exactly the feeling you have about M-85. I hooked it up played it through my Cerwin Vegas and I found myself lacking mids and highs, it wasn't as crisp as my Yamaha M-70s. So as much as it pains me not to have this amplifier there was no reason for me to keep it, the 70s were just on a whole Other level.

    The MX-1000 is a very revealing amp. What you put in is what comes out.

    He is not the only one. Others have done it. If the amp was restored, it will do just fine.
    If not, Chernobyl waiting to happen.

    Nice setup. I like the R2R.
    I would not keep the amp in that tight space tho. You'll be baking somethin'

    The MX-1000 runs very cool by design and idles at only 70w. It has plenty of ventilation ...even the PCBs have holes through them. but....cover it with something and you will be backing it ...and whatever is above. If covered, even at idle, those transformers will get very hot.

    I can cook dinner on my M-80 running auto class A but the MX1000 stays very cool even under heavy load. Klipsh RF7ii's are my speakers and you can rip someones head off very nicely with these amps, and have them smiling while they go deaf. :)

    I would agree with you if my two M-70s didn't sound so good compared to MX-1000, the bass was fine, but mids and highs were lacking. I used
    the same inputs from the M-70s and the 4 Cerwin Vega 15s and the sound was like night and day.

    Then I would say you need to have that MX looked at.
