Speakers for Accuphase amps

[meltemi]

Yesterday, I had a first opportunity to listen to the new B&W 800 D3 with a top of the line Accuphase chain (DP-720 / C-3850 / A-200) and full Audioquest WEL Signature cabling
(XLR interconnects and full range speaker biwiring).

Awesome.
An absolutely perfect match and a strong recommendation to all C-3850 /A-200 owners.
Honestly, I had not known, that the Accuphase reference chain was that good.
(So far I have B&W 800 D2, but this will change, when the D3's become available.)

The V3's are a bargain now, saw a set for 3000 GBP on ebay.
They have very low distortion, great resolution, coherence from top to bottom is excellent, closed box design. I find them very musical, a joy to listen too for longer periods.

Hi! I just bought an Accuphase E-303. And it works exactly at 53° C.
Is recommended to use some kind of cooling to preserve the amp?
Thanks

I have 2 a200s running as monoblocks. Perfection to my ear.

53C (127F) on the heatsinks of an E-600 Class A amp is hot, but not unreasonable. However, The same temp on an E-303 Class AB amp is quite hot and would check the offset & bias on the output stages if were mine. While the E-270 is a considerably different/newer piece, mine runs quite cool and is barely warm to the touch at normal listening levels.

Is safe to touch the offset and bias potenciometers? Or i have to send it to a service?
I live in Argentina Btw

Not if you do not know what you are doing, which would include owning the service manual.

Do you have a service center for Accuphase in Argentina? If so, I would ask them about the temperature & any possible service. Accuphase USA is very "touchy" about their products and will not share schematics or service manuals on any of the Accuphase products. Even the vintage models. Do not know if that is just the USA or world-wide.

Thanks for the reply.
We don’t have service of accuphase here.
I downloaded the schematics from a website.
I gonna keep looking.

The schematic may have #'d TP (test points) listed. Having the full manual would tell you which TPs to use for bias & offset. That said, not all amps have these adjustments.
