Tube Preamp with PS Audio P300

I have heard some negative things about certain equipment being run through the PS Audio. With something as expensive as a BAT pre, I'd email BAT and ask them directly.

Do not bother. The P300 cannot handle the current demands of the BAT preamp.

PP-300 may not provide enough start up current for BAT. You might want to check with Victor at BAT or Paul at PS Audio about that. My VK-50SE is powered by a PP-600 with great results. Some MW settings will cause the transformers to buzz. Mine is set at PS-2 and it is dead silent.

If you could stretch your budget a bit I would strongly suggest getting a PP-600 instead. Although a PP-300 is rated at 300W but in reality, you don’t want to push it beyond 200 or it will get very hot – even with the internal fan. And once you try it with a piece of your equipment, you will want to plug in more and very soon a PP-300 will run out of juice. PP-600 is rated at 720W and is more flexible. I have my entire front-ends (5 pieces) plus a 53” RPTV powered by a single PP-600 without any problem. They draw a total of 420W.

BTW, if you are getting the PP-600, make sure you order the new top plate with a vent slot. It helps cool down the unit a lot.
