More than meets the eye
and a few other things
the C-70 also has
Varigain Volume control
separate direct phono inputs for MM and MC
a little larger power supply
distortion is a little lower in some places

The C-50 has separate phono inputs for MC, too. Must be some more difference as the C-70 is a bit heavier.

Yes the C-50 does have a separate MM non direct input but not a Separate direct input.

But yeah if you can get a C-50 for a few bucks I would go for it.
I see you have several Yamaha systems :tresbon: including the C-4,
And OMG the NS-2000 speakers :ntwrthy:
I have the C-4, C-50, C-70, C-60
IMO the C-4 sounds a bit better than the C-50 and IMO the C-70 sounds best of all 4 of my Yamaha preamps.
And this may be due to the Varigain volume control...to the best of my knowledge (which BTW is limited) Yamaha only did this once and that was in the C-70
I forgot to mention the C-70 front panel has a tone bypass switch too

I would use the C-50 as phono pre together with my A-S2000, so the lack of varigain is not an issue. BTW, the A-S2000 is a wonderful amplifier and a perfect match for the NS-2000. My only complaint is that phono MM sounds a bit too bright and that I cannot connect 2 TT's, so I prefer an external phono stage. In my setup MM carts (AT20Sla, AT150MLX & Goldring 2500) sound best with the C-4, for MC (AT33PTG) I prefer the C-80.

I have a C70 lying around that needs some servicing, I can make some pictures of the guts if you'd like.

Would you like to sell it to me?:yes:
I have a C-70 and never heard of "Varigain" what is it exactly?

....the varigain volume control attenuates the gain of the amplifier instead of bleeding off portions of the signal through resistord....improving S/N ratio.
Accuphase has now reinvented varigain: AAVA is a totally new volume control concept that does away with the variable resistor and assures optimum performance and sound quality. Because the music signal does not have to pass through any variable resistors, there is no adverse influence from changes in impedance. This means that the outstanding S/N ratio and excellent THD of the amplifier is not compromised in any way, and the same superb sound quality will be obtained at any volume setting.
Thanks for the explanation. I never heard the term before. I will add that I am very pleased the the C-70. The direct phono sounds great. Sure is a lot of gain though.

That sounds like a cool idea, the C-50 should do a fine job.
I really like the old school look of A-S2000 and was glad to see Yamaha getting back to their audiophile roots and would love to see some preamps come out one of these days.
