B & W Matrix 801 S3 and tube amplifier

CAM 350 is great amp if you can get within your budget.

There are a lot of good amps. The trick is finding the right match.

in any situation CAM350 fits well budget components and way better than 60W CJ.
if funds will allow CAM350 will be easy to sell/replace.

Hi Pvctor

Attached are a couple of graphs from B&W for the 801 matrix.

801 Impedance Curve

Note the 4 ohm symbol. Not sure why it was plotted on this paper. You can also find plotted graphs on the stereophile review of the S2.

801 Frequency Response with & without BAF

The above graph is from the UK. All 800 matrix series B&W speakers are an active design as you are probably aware, and were meant to be run with the BAF and were shipped with them. Unfortunately these ended up getting lost as speakers went from one owner to the next.
The BAF’s allow for extension to 20hz on 801’s. This is documented in the owners manuals. The BAF’s also make the speaker more sensitive then the advertised 87 db. More bass extension and sensitivity is documented in the B&W BAF owners manual as well. My listening confirms this. I have owned my 801 S3 for 18 years. I own a couple different BAF versions.

Hope this helps and good luck with them.

Any questions you can reach out to me at bcpguy@bell.net

Cheers

that is to see from the graphs that mid-powered 60wpc tube amp will always and constantly have a current deficit.
