Recommendation for Yamaha Power Amp

I would like to purchase a reasonably affordable, but top performing Yamaha Power Amp which will stop my upgraditis! There are many for sale, but which should I go for ? Do I go for the B-2(problem if VFets fail),M-4, M-80, M-85 or the MX-830, MX-1000 etc. Help please!
 
well hifileslie, I have owned both the M-80 and M-2(bigger bro to the M-4). Sold my M-80, still have my beat-up M-2(currently driving my twin 12" Shiva subs). I like Yamaha! Unfortunately, if you're similar to many of us here....the upgraditis bug never surrenders her bite on you! Get 1 of each. ;)
 
Best price would be for the M-70, TOTL in 1982. 200 wpc.
The 1984-85 TOTL was the 250 wpc M-80. The 1986 M-85 runs 260 wpc, but otherwise output matches the M-80.
 
M 2, M 4, hell just about any of the M series amps are awsome. I have owned the M 50 and it was a great performer @ 120-125 wpc. The one the I want is the M 4. They are relatively inexpensive, built extremley well, and I've heard nothing but good things about there performance. I want two so I can run them in mono at somewhere around 250wpc :yes:
 
My vote goes to the M-80. In a moment of stupidity I traded it but i"m now trying to get it back from the guy. i miss it and if she ever does return to this house she won't leave again.
 
Sound wise (no upgrade) the selection shall be between B-2, B-2x and M-2. The MX-2000 shall also be good, as I know it is the little sister to the extremely rear MX-10000 (and not the bigger brother to the MX-1000). A little more easy to get hands on is the M-80/85 (30W class A); if you don’t need that much power the M-65 is of the same series as the M-85.

Just for another thought...if for example you have a C-70 preamp, then you can have two amplifiers hooked up - one amp for left and one amp for right. That can make for very satisfying sound. You could probably pick up two M-50's for cheap and end up with over 200 wpc.
 
If I remember correctly, the M-50 and M-70 can't do class A. But the idea is right, if you need extreme power, the top Yamaha pre amps can run 2 power amps.

I think there is a guy here on AK that is running 2 M-80 or 85s like that, but it is an extreme powerful setup. I have never seen any numbers on the power rating of the M-85 running in a bridged setup, but it must be over 500W RMS@8ohm and about 1600W RMS@2ohm.
 
I know that guy

I know that guy running two m-80's thru his c-70 preamp :D but he also has a m-35 m-45 (2)CA410II,610II and a b-2 amp also seems like he loves his yammie power he doesnt want to try to guess how much power his amps make bridged :scratch2: one day he dreams of running 2 b-2's

This is a great resourse, Ive been looking for something like this for a while so i can determain what are the better Yamaha amps. How does the M-4 and B-6 compare? Any details on these units?

If you have time it would be great if you could provide the same details regarding the Preamps such as C-2, C-2a, C-2x, C-4...C-80 and so on. :banana::banana:
 
That info is straight from the Orion Blue Book. The used values however are worthless.
 
I heard the M series, once the outputs are blown are basically boat anchors. What truth is there to what I heard?
