Yamaha amplifiers

Just curious how you guys feel about yamaha amplifiers? Currently have a mx-630 with a nad 1130 preamp. have been looking at a c-70/m-70 setup but not sure on a price. Also open to other brands just not sure what to look for. I have seen a couple adcoms for sale im my area of minneapolis as well.
M4.6, 5jr, Monitor 5, 7, 10. RTA 11tl. SDA 2B.

    Yammy's seem to be well received here ( I have a low class receiver in the garage at the moment that I can't really hate on) but I'm curious if you have ever put a NAD amp behind the NAD pre?

    I also just nabbed an Adcom from the FS section to play with. No impressions yet :/

    I think Yamaha used to be better than they are now. I've never owned a Yamaha amp or receiver. If I was going to, it'd be an older one. And I'd be REALLY CAREFUL about verifying the 4-ohm specs.

    They can still build a competent amp...but you'd better be prepared to dig deep into the wallet before taking it home.

    Last I looked, if you wanted REAL 4-ohm capability, you were looking at $1600 and up. Phony 4-ohm capability was what the less-expensive offerings had--a switch on the back panel that strangles the power supply so the poor thing doesn't cook into a "low impedance" load. (I don't consider 4-ohm nominal to be "low" impedance...but Yamaha does.)

    You'd better not proclaim any of those to be dump finds or I might officially be jealous. :'(

    Nope, neither of those was (a dump find).
    The CA-610II I bought new from Soundscape in Baltimore, MD -- in (if memory serves) 1978. It has served admirably for nigh-on four decades, with one repair (when we lived in California).

    The CA-800 I bought used but restored some years back. It is a very good sounding amplifier -- almost amazingly so when set to Class A operation (for something like 10 wpc).

    Yes, a buddy up the road from me has a CR-800 that he bought new with Large Advents, and I am constantly amazed at how good that baby sounds. ;)

    I found this AV34 at a thrift store for $25. It has served me VERY well in the two years I have been using it, a stout 100 watts that drives my SDA2Bs without strain. Although not a looker she sounds pretty good.

    I believe that was my first surround sound receiver I ever bought new. Used it for 20 years! :p B) :)

    I think that looks awesome! I love receivers with that kind of design for some reason. Kind similar looking to my new Technics:

    sure it has a flat response, and sure it has a lot of detail, and yes, it has good and clear lows. But is it enjoyable to listen to? Does it make you grin ear to ear? That’s what really matters.

    (In the interest of full disclosure -- the Yamaha TC-1000 looks considerably more impressive than it actually is. Yamaha did make some pretty good cassette decks, though... like the K-1000, an example of which, sadly, I do not have.)

    What, really? You never saw one of Yamaha's famous ear speakers? :p

    7dfb9pkeu7db.png
    4r3tlqoz9t6o.png

    That is a single NS-15. Found it at the dump and ultimately gave it away -- what were the odds of finding another single? :)

    Yamaha sold several variants of the same basic design -- many were for pro/commercial audio (sound reinforcement) but some, like the NS-15, were for domestic use.

    The NS-15 is particularly interesting as it is essentially just an open baffle. Here're some photos of the flip side.

    "How does it sound?" I hear you ask. :)

    Actually, I thought it sounded decent. Very sensitive -- it wasn't the kind of loudspeaker I'd build a mono system around, though... and it wasn't anything so special it seemed worth waiting a decade or two to find a mate. Besides, chances are I'd have found a pair... and then I'd have had three, which wouldn't be an improvement ;)

    Yamaha = boring to me. The "M" amps were pretty over-hyped then, and still are, IMO. So were the pre's that went with them. I'd take a Nak CA-5 over a Yam C-70 any day.

    Natural Sound = lifeless and boring.

    I never connected with any Yammy stuff. Sold it for years because that's what people wanted back in the day. A sales commission is a sales commission, but personally I preferred Nakamichi, Luxman and Adcom of the day.

    Just my .02c since you asked

    Not to derail the thread, but I can't seem to find any Nakamichi anywhere anymore.

    But anywho, I agree with heiney, my yammy is rather lifeless, that's why it's in the garage and being replaced.
  • pitdogg2pitdogg2 Posts: 10,011
    nope never seen nor heard them Doc. interesting.

    I liked my Yamaha integrated amps I had. I never had any amps. But those Nak's were and still are very nice..

    The only problem with the Nak stuff and to a certain extent the older Yammy stuff is they need refreshing by now. I had a Nak CA-5 pre for quite awhile (built in 1987, IIRC and bought used in about 1990) and I had to have some caps replaced on or around 2007-2008 before I sold it. They started making noise.

    This older gear is sometimes not worth the hassle unless your good under the hood, as paying a tech to do it gets pricey fast. Or they've been verifiably serviced.
