Yamaha amp?

THE YAMAHA MX1000 IS CRAP COMPARED TO THE YAMAHA B=1,B2, OR B2X. I HAVE OWBED ALL THREE. ALL OF THESE WERE DUAL MONO CLASS A/B AMPS. THE B1 AND B2 WERE V FET AMPS WHICH WERE UNIQUE IN THERE SOUND AS MORE TUBE LIKE WHEN WARMED UP FOR AT LEAST THIRTY MINUTES. THE B2X WAS PERHAPS THE CLEANEST AMP WITH THE BEST BASS AND CLEAREST HIGHS. I HAD THE M80,M85,MX1000,M2,M4, M70,AND HAD ALL OF THEM WITH REALLY CLEAN MAGNEPAN TYMPANI SPEAKERS WHICH WOULD ALLOW YOU TO HEAR VERY SMALL DIFFERENCES IN ELECTRONICS. I STILL OWN A YAMAHA B2 C2,T2 SETUP BUT SOLD THE B2X FOR 1500 AS THE ORIGINAL OWNER. I ONLY REPLACED IT WITH A SPECTRAL/MARSH DESIGNED MONSTER POWER MPA 2250 TWO CHANNEL X TWO FOR MY MAGNEPAN TYMPANI 4 AND EXTRA TYMPANI WOOFER SETUP.

M 2. Aka the beast! 200 watts per channel and Yamaha's first amp after
Giving up FET's in late 70's and 80. Buy one if you can.

I have an M70 and MX-2000. The MX-2000 ($4000 when new) is an entirely different design than the MX-1000, and is a scaled down version of the legendary MX-10,000 ($11000 when new). The MX-2000 is a very serious amp - almost a work of art, and was available by special order only. It only puts out 130 watts into 8 ohms, but those are some very refined watts. It's heavy at 62 pounds, pure class A MOSFET design, and all hand-made solid construction w/titanium-cherry finish. Sound is smooth and very detailed, with an enormous 3D soundstage. Beautiful to listen to, and even to look at. Consider yourself extremely lucky if you ever get your hands on one of these. The M70 is a good amp, but the MX-2000 is in another league entirely. I'm still looking for an amp to better it (and I've auditioned quite a few lately).

Have both M70 & MX1000. I also use higher end amps, such as Krell and BAT. I keep the older Yamahas around as spares. Frankly, they do not give much away to their newer, more expensive breathren. Between the two Yamaha models, I find that the M-70 is current-biased higher than the MX1000 and seems therefore to have a slightly warmer sound. The sound from these older amps is very full and quite impressive, IMO. I've detected nothing in their sound that suggests they become unstable at low impedance (e.g., w/ my Martin Logans). The M-70 can be had for less than $300. Very, very hard to beat.

Steve,

The problem is not in the speakers. But it could be in your pre amp or interconnect cables. First I would try a different power amp and interconnect cables.

If the problem is eliminated it is the cables or the MX1000. If the problem persits, the signal is inconsistant from your pre amp.

Hello,

I am hoping to get input from someone before I take in for repair. I own a Yamaha MX1000 amp and I have it hooked up to Klipsh Lascala Speakers. The problem I am having is the Right Channel reads lower than the left channel (output bars on the amp). The right speaker does not have full sound and every once in a while it kicks in to full sound and lasts for a while but then cuts back down again. Sometime it stays full sound both channels for somewhat a long period of time and then cuts down again. Do you think it is a problem with the amplifier or the speaker ? I am going to hook up another set of speakers but I was just curious if someone has some input on this dilema. Thanks a lot and take care. Regards, Steve Johnson

I still own an MX1000. I keep it in the closet as a spare .
Its actually quite good and held its own to my ears compared to The Big Rotel, which I owned then sold, and Anthem , which I use on my surround. I now own a Classe 301 , which is in a different league for my mains, but a couple of years ago I had to use it as a spare when I had to have my Classe repaired, and The Yamaha sounded real good , when paired with my current electronics. If someone is offering it to you at a real low price and you cannot spend $1000.00-$2000.00 for a new amp, then in that context, the Yamaha is quite good.

I think you may be refering to the m70.A little older than the MX1000.The m70 is 200wpc the MX1000 260WPC.I have at one point or another owed both.Good amps?...yes,but watts are not everthing.You should consider some of the lower end u.s. made amps B&K,ACURUS,just to name a few.They may not have 260wpc but are just as loud,if not louder,and much better sound,the extra $50 is money well spent.I went from yamaha to acurus to ocm to bryston to krell,save yourself a step...HAPPY LISTENING!

I am not sure but I think what you may be interested in
is a Yamaha MX1000U.

It Was pretty beastly, but keep the load at 4ohms or
greater.

The MX1000 had trademark red light power bars that displayed
up the center of the face plate.

A number of DJ's in the midwest still have them in service.
