Post Subject: The rub with battery ampsPosted by Paul S on: 4/30/2008
Mats, believe me, I'd love to get off the frickin' grid altogether.  But if I'm looking at >20 car batteries just for the K&K phono stage, then how many angels will fit on the head of a pin?  Ironically, the K&K also uses JFETs...

I remember vaguely looking into the Pass design when it first came out, and now I am having fuzzy "memories" that the thing effectively reminded me of an OTL, in terms of its power delivery, and/or it dropped off fast in terms of useable power after its "1st Watt".

In any case, remember that this Pass design is not very efficient - at all - needing >300 watts at idle!  And I wonder how effective the stated 15 watts is, since I need them all, and then some.

If I ever heard an amp with "no obvious problems", I would certainly, soon enough, have an equal-and-opposite, knee-jerk sense of suspicion.

Naturally, I will check the battery amp out ASAP.

If it's Swiss, it has to be good (and expensive), right?

Since we're on the topic of SS, how about op-amp power amps...

Best regards,
Paul S
