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 8tl. RTA 11T. 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 :/

    Stop showing off, Doc. It's unbecoming of a gentleman such as yourself.

    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:

    (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: 10,226
    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.
