What is the pecking order and chronology with the Yamaha preamps? Is the CX-800 a step up or down from the CX-830? Is the CX-1000 a newer version of the CX-1? What about the U versions like the CX-800U? Thanks!

CX-1 is newer than the CX-1000.
Don't quote me, but I think I remember that the "U" designates USA model.
I have had several Yamaha preamps (C-80, C-2x, & CX-2) and they are all excellent performers.

Thanks Bully for the response. I own a C-2a but didn't know how the other models ranked from a Yamaha model line perspective. I read on a audiogon listing that the U model was digital. Not sure what was digital but that's what the listing had.

I have just gotten a CX-600U, which seems good but not fabulous. The seller had lost the remote (why does that always happen?)--does anyone know of sources for remotes at decent prices, used ones even?

I've got a C-80 that came with a T-80 and a M-80 (broken). The C-80 is a very nice performer that I would recommend. Has interesting parametric tone controls.

I use the C70 and I love it! It is the only one in that particular line that omits the loudness contour feature. I've owned the C80 and C60 too and while they are great units, I always had a problem with the way they sounded compared to the C70 because it seems the loudness contour control was never completely out of the circuit even though the control was set at "0". That is a small gripe. I've read many explainations of what the "U" designation means and I still can't figure it out either. No one explanation seems to hold true across the board. Here is a link to a great place to start looking for that remote: http://www.audiotubes.com/remoinst.htm I hope you find what you need.

C-1 (VFET, very complex) '76 MRSP $1,800.
C-2 '77 $650.
C-2a '79 $950
C-2x '85 $1,305
C-85 '86 $850.
CX-1000 '88 $1,200.
CX-2000 '88 $1,500.
CX-10000 '87 $7,500.
CX-1 '93 $1,200.

These are the TOTL models. CX-830 '90. Am guessing it is comparable to the CX-800 '88, but something newer about it (20 bit rather than 18 bit DAC, perhaps - has an updated learning remote, but nothing else obvious).

Have owned all the TOTL except the C-1 & CX-2000/10000. Based on sonics, my older of precedence is: C-2x, C-2a/C-85, CX-1, CX-1000, C-2. Another great one is the C-65, one down from the C-85 (also was a C45). The C-4 & C-6 were the next down from the C-2a. There was a C-80/70/60, as well. But they were only there for a year until the C-85 line replaced them.

I have just gotten a CX-600U, which seems good but not fabulous. The seller had lost the remote (why does that always happen?)--does anyone know of sources for remotes at decent prices, used ones even?Try Yamaha parts http://www.yamaha.com/yec/generaldetail.html?CNTID=451690&CTID=5010100. Generally, their cost is quite reasonable on remotes, unless you want a learning model. Also, do a search for on eBay. They pop up quite often. Any of them that run that vintage receiver will also run the preamp.

Can't wait to put the hammer down with the C-80, M-80, T-80 combo. My M-80 is being repaired. My tech calls the M-80 a "flamethrower" because it runs very hot in class A and tends to catch fire. He showed me his parts M-80 that had a hole burned into one of the boards.

I'm running the C-80 through a Luxman M-117 and that is a very nice combo.

According to Yamaha the U stands for US model.

B-2 has it pretty much right with the ranking of the pre's, except that I would put the CX-1000 above the C-85 at any time (I have bough). Some of this disagreement might be due to old components (cap's) in either my C-85 or B-2's CX-1000.

The C-70 was not the same year as the C-80 and 60; the C-70 came with the C-50 in 1982. The C-80 with the C-60 and C-40 in 1984. Then the C-85 line came in 1986.

The C-2a is an upgrade of the C-2 (1 unit size) witch was only in the market for about one year and was not considered that great. The C-2a came the same year as the C-4 but is not from the same line (1979). The C-6 came with the B-6 in 1980 and might be a down grade of the C-4.

Remember, when t-r-m is giving info, it is for Europe (and probably ROW), while my info is for NA. Have never understood the marketing decisions made by Yamaha, Sony and the rest concerning timing and models offered in various markets. Probably has something to do with warehouse size and sales of particular units from those warehouses.:D Other than the TOTL gear that made it to Europe and not to NA. Can't think of any examples of TOTL gear that came here but not to Europe.

Thanks t-r-m and Glenn. I've bookmarked this thread so I can refer back to it. I've got my B-2 hooked up with my C-2a and with newer SACD material it's fabulous. The Phono section is not so great on this unit with my YP-D6 and Grado Gold cartridge. I'll have to send it to Echowars after the new year and get some Blackgates installed.

A question from another thread. Is your YP-D6 semi-auto or manual?

the-real-mandak
12-03-2006, 10:01 PM
B-2 that is true indeed, maybe because we paid more and had less trade restrictions to the Far East by tradition. I don't have solid numbers on it but I also think Europe was a bigger Yamaha market than the US (maybe not in the 70's).

But notice the years of release, 1975 (C-1), 77, 79 then a little jump, 80, 82, 84, 86, 88, 90 and finally 93 (CX-1). It pretty much follows a 2 year pattern witch fits the US data I have from the Orion. Only the statement units does not follow this pattern, the C-2x in 85, CX-10000 in 87 and CX-1 in 93.

All the units mentioned here are in the Orion Blue Book (a US price tool), so they must have been in the US. But it is a fact that Yamaha has made units that newer made it to the US; I just don't think it covers the amp's and pre's.

My first preamp was a C-6 purchased in 1981. It had a funky parabolic equalizer which I never did find that useful. I still have it but never use it anymore. The LED lights act up weirdly(sometimes on, sometimes not), and the large volume control is wobbly. A problem that is not as intuitive to fix as I might have thought. More importantly the sound is not all that great. The $20 C-2x that I found at GW last year is totally in another league.

Yamaha B-2
01-14-2007, 08:41 AM
Yes, for the ~$900 difference in price (some 25 years ago), there should be a big difference in build quality and sound.

soundoc03
01-14-2007, 02:03 PM
No disagreement here, just somewhat ironic that for what the C-6 would fetch on eBay I picked up an infinitely better preamp at the GW. A good example as to what makes this hobby so much fun and economical.
For anyone considering a C-6, which I would not recommmend, when comparing the line inputs with a CDP vs. directly outputing the CDP into the power amp, the C-6 darkens and dulls the sound substantially. I have not recently tried the phono stage which might in all fairness be a little better. It does to it's credit have a MC/MM control. I am currently enjoying the phono stage of the C-2x outputed to the amp section of a MCS-3125. The TT is a PD-375 with a Grace F-9e. Speakers are B&W 805s. This set up is one of the best sounding arrangements I have put together yet.

The C80 was nice, a beautiful phono preamp, amazingly built but the 4 gang plastic film volume control is the weak part- they are impossible to replace, clean or repair. Also, they have several hot spots inside and caps dry out frequently. The last one I sold for AU$550 to a collector. I have a mint, boxed CX1000 w/remote books etc and honestly, it blows them all out of the water. 12kg, onboard D/A's and as silent as a tomb. I'd back it to eat the older C80/85 on line signals whereas the phono stage is easily bettered by the older ones. Sound is typical Yamaha though- clean accurate and tight, but a bit boring sometimes -too good for itself. The remotes are impossible to get- I found a half melted remote for a CX600 which works, but you can use any old yamaha remote- they are like Sony, all the codes remained the same, so you can even grab a modern DSP disaster and copy the source, volume and power mute etc into a universal remote.

I have a minty C-80 in original box. I did have a second C-80 I got off eBay that I used for years until I sold it.
I found the C-80 to be a truly fine performer with an excellent phono section. I have also had the fabulous C-2x and now have the fine CX-2 paired with my M-80.
I can say I have really liked all the Yamaha gear I've had or have now.

In the U.S., at least, you can buy the remotes new from Yamaha for the CX-1000. Something like $45USD. Also, most any of their receiver remotes from the same years are essentially the same and will run the preamp without a problem.

While nice to see a compilation, his prices in Euro's are higher than our prices were in $USD. Not sure when this was put together, but must have been several years ago when the Euro was less than a $USD.

BTW - What is Farben?

The Euro was not even around when most of those items were made so someone has merely performed some rough calculations.

the-real-mandak
01-31-2007, 04:33 PM
The prices in his compilation are German MSRP, they were not the same all over Europe, here in Denmark we would have a Danish MSRP witch was higher than the German price. On top of this came that the sales tax in Germany was about 12%, the Danish 20-25%. Just to give an example of different prices here in the EU, of curse now days things have changed so the MSRP is about the same. The exchange he did was from D-Mark to Euro and using the official currency rate (I don't know if he did that, but it would be the right way to do it).

----EDIT----
The price here in northern Europe has always been higher than in the US.

Time to Revive an old thread-
I picked up a Yamaha CX-600U control/Preamp
this evening at my local GW for $10.00!
It powered up and all the function lights lit up
A couple of light scratches on the top.
So I brought it home and popped the lid,Gave all
the pots & switches a good Deoxit cleaning before
hooking it up.Its running my Carver M1.5T amp
and its much more musical than the Carver C-1
Im used to listening to it through.
No remote and the volume knob has alittle slack
like it needs to be tightened down.
I'll post some Pic's tomorrow in the "Natural light"

I will argue that the C-70 1982-84, C-80 1984-85, and C-85 1986 (Orion) were all TOTL. The C-2x (I had one, superb) in 1985 was a one-off, not related to the "regular" series topped by the C-80. I won't argue, but gotta get it out there. The C-80 is a pure-D Yamaha that disappears, just gets out of the way of the music.
Now I also have the CX-2, not TOTL which is odd for me, but it is a fine fine invisible preamp with a VERY fine phono section--the extra "video" inputs are just extra inputs for whatever I may want to use--SACD or ???
What I've heard from Yamaha gear is that I *don't* hear it. What more can one ask of a stereo--amplify the source signal without adding anything.
Yeah, beat me with a stick, I sold my M-80, but I still have a pristine M-70, the C-80 (mint), the CX-2, and the trusty R-2000 receiver. Yeppers, and TWO T-80 tuners that sound great and pull in stations like a hoover.
I did have the smaller CR-1040 for a while, that I got to give to my brother, and even the mid-line unit had that superb Yamaha non-sound Natural Sound.
Yeah, I'm a Yamaha nut.

your best bet is a hifi store that survived from the late 80's and was a yamaha dealer- there's still some around. They usually will have many boxes of synchro, RS etc cables that weren't used when they did installations. I scored a bunch when I asked for free.

I found this old thread and didn't notice much discussion of the C-45. I just ran across a C-45 at a local shop for $25. I've been on the lookout for a C-60/65 or C-80/85, and I'd love a CX-1000 although the ones that pop up are out of my price range at the moment.

So, does anyone have any thoughts on the C-45? Is it a decent unit? Since it's in the family of the C-65 and C-85, does it have the same quality circuitry, just with a reduced number of features? I'm especially interested in the quality of its phono stage...I know it doesn't have all of the switchable impedances of the higher-up models, but is the QUALITY of the phono signal the same for use with standard 47-kohm moving magnet and 100-ohm moving coil cartridges? Is it neutral/flat like other Yamaha pre's?

Also, does anyone know if you can use the "video" input as a standard "aux" input?

I'm thinking of picking it up and using it in the interim until I come across one of the higher-up models at a good price. $25 also seems pretty cheap.

at $25 it's a no brainer, go get it.

I don't have personal experince with the C-45, but I will garantee the usally neutral Yamaha sound. The phono will also be ok, even I would rec. to go for a C-60/65 or better. It all depends where you come from and what you expecte.

CD, Video, Tape and Tuner input has the same sensitivity, so yes.

Just for info, I do have the C-50, 60, 80, 85, CX-1000 and C-2x.

Hi Yammy-buddies !!

I just got my hands on a C-80 for lunch. A cool story, it was for sale in another province of the country so I asked the guy about shipping and he told me "a friend of mine is travelling to your place next week, he can take it on the plane"... and here we are !!

I got it for $125, not a GW $5 score but a good price still, last one I saw on the Bay went for $384 + shipping last week!!

I'll be back soon to comment on it :)
