Differences between Accuphase C-2820 and C-3800?

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.

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 Bvdiman - as Nvp has correctly pointed out, the A-46 has two switches on its front panel for Speaker A and Speaker B. I have to manually switch one off and the other on when alternating between speakers.

I use Auditorium 23 and Crystal Microdiamond speaker cables. As for the C-3800, no I haven't gotten round to listening to it yet.

Hi Nvp - no problem with your FM Acoustic question since I too would be interested in learning the answer!:)

When I compared the A-46 and P-6100 I used my E-560 integrated as the preamp (there is an Ext Pre button to press). Even though the 6100 was very good, I believe the class A sound is a better match for a speaker with ribbon tweeters.
