Differences between Accuphase C-2820 and C-3800?

Hi Classact, interesting.. In so doing, do you use switch or manually? - as I don't recall seeing any A/B speaker select switch in most of their recent amps. My vintage integrated (E302 - '80s) did have them though. What cabling (IC, SC, PC) you using?

The C3800 is an extremely well built and great sounding piece. Have you gotten around to listen yet? Or perhaps already using one now? ;)

Hi Bvdiman - yes the K6s sounds fabulous with the A-46, but they are not bi-wired. I actually connect a second pair of speakers to the amp's speaker B terminals so I can enjoy a different sound when I want it.

For example, for late night listening sometimes the K6 can be a bit overpowering so I switch speakers to something more mellow. Currently, my speaker B is the Spendor SA-1 but I'm considering trying Harbeth as well...

Hi Classact, are you using the A-46 as yet? If so, did you find bi-wiring them wrought much further improvement? Appreciate if you could extent on the difference.

Can imagine how mighty fine your ProAc's are sounding now driven by A-46.. Enjoy!

Hi Nvp - apologies for the late reply. Yes the upgrade bug has bitten and yes I have listened to the A-46 versus the P-6100 and preferred the A-46 which I thought was a lot more musical, especially with the ribbons on my K6s. I considered the A-65 but it doesn't have two speaker outputs, which is what I need. So it'll be the A-46 for me.

As for preamps - no, I haven't listened to any yet. I figured I'd add the A-46 first, then wait a while (and save like mad!).

Dfwmediagroup - thanks very much for your input. Yes, I think if I do decide on a dedicated preamp, I should seriously consider the C-3800. Will have to see how the finances go after the A-46 purchase, and also whether I can have a home demo of the 2820 against the 3800 to see how each performs in my system.

Many thanks again for your inputs guys.

Hey Classact, any news so far? Did you listen and/or compared these pre-amps?

Wow, Paul you really know your Accuphase. As for me, I'm moving on, it's just too expensive here in the US, and the resale is poor. Thanks again for all of your help over the last year or so.

Hi Classact, it looks like the upgrade and Accuphase bugs have bitten you well, viz. less than a year ago you were contemplating whether to buy an Accuphase or a Musical Fidelity integrated, and now you are thinking to go after the Accuphase top of the line pre-aplifier.

While I do not have experience with either pre-amp, I advise you to proceed with care and patience. I know you have ProAc Response K6 speakers and you were planing to buy an Accuphase A-46 power amp. IMO none of the two is no where near the league of the C-3800 pre-amp. Consequently, the price difference between the C-2820 and C-3800 might be better spent in another direction, e.g. buy an A-65 instead of an A-46, or use it to partially cove the price of a good Accuphase digital source. I would also not dismiss just yet the Accuphase solid state power amps, e.g. the P-6100, P-7100 or the evolution of P-7100 (which should be release in the very near future).

Given the amounts involved I would not take a decision before doing the following comparisons:

1) A-46 & C-2420 vs. A-46 & C-2820
2) A-46 & C-2820 vs. A-65 & C-2820
3) A-65 & C-2820 vs. A-65 & C-3800

Oce you have settled on a pre-amp also compare the A-46, A-65 and P-6100 power amps. (Of course, you should use your speakers when make any of these test.)

Dfwmediagroup, maybe you could shad some more light on the differences between the power amps I have mentioned above. You seems to be a deal so probably you have much more experience with these amps than me.

Good luck and keep us posted.
Paul

Both are beautiful pieces. The 3800 has a more robust power supply with greater capacitance. As expected, from a sonic standpoint, the extra expenditure gets you more in the way of dynamic contrasts, bottom end authority, transparency, soundstaging and a slightly lower noise floor. The 2820 design allows for the inclusion of the optional internal phono stage, whereas the 3800 does not. All that aside, both preamps are world class and you can't go wrong with either of them. If you can spare the extra cash, go for the big dog.
