charles, I have NO idea what 8-Watt SET poweramp I'd prefer. The reviews led me to believe...

...that the Frank.II was about as good as money could buy, and that's why I bought them. BUT, same as in about all other areas, you don't discover the shortcomings until you've paid your money and received the product. Blume bragged about all-polypropylene-cap main PS...and I got cheap, edgy-sounding Solen FastCaps. He bragged about NO coupling caps in the signal path...and I got a not-quite-as-cheap Solen 'propylene-film-and-foil coupling cap. He bragged about highest-quality Teflon caps in the amp...and there are none to be found. I believe the design is very good, but the quality of almost-all parts is not-at-all excellent and in fact (IMO, at least) rather poor. For instance, what high-end-amp designer would use resistors and capacitors with magnetic leads? Who would use magnetic hookup wire????????????????

Oh well...all that stuff will be gone in a couple months.

And RC Daniel is correct--I have NO interest nor adequate knowledge to build amps myself. If I built a pair, probably one wouldn't work at all and the other would hum so badly it'd be unusable, and then it'd cost me a kilobuck to get them running.

I initially missed your question about matching the speakers--yes indeed they seem to drive the MR and tweeters of the Serenity Super-7s very well. I've not changed the coupling-cap value nor added a front-end high-pass filter, so the amps are driving full-range signal into the MR/tweeter section. My intention is to use a 0.01uF coupling cap which, with its 330K load resistor, will create a 48Hz high-pass filter, which will reduce--I almost typed 'block', which of course filter caps don't do--much bass energy from the midrange drivers, and I imagine they'll sound better for it.

A VERY-golden-eared goodbuddy heard my system the other nite and uttered 'That's the best I've ever heard this' while listening. He also said that my system was now about the best he has ever heard, all of which made me feel really good...and it'll be sounding even better in a couple months. :-)
