I dunno. A used pair of Khorns can be picked up well under $2K if you are patient and spread your net well. Yes they are big, but tucked in the corners, they take up less space than one might expect. Also, there is Great Plains Audio....

A pair of new 604s will also run around $2K and can be built into the enclosures of your choice. I have two pair of the Altec 604s, one set in open baffles, and the other set in slightly modified Altec 828 cabinets. Both sets sound great.
Both the Khorns and 604s are well north of 100 db/w/m and a 45 SET amp will give you plenty of volume for your listening needs.
I'm glad Beetlebum likes his 45. Personally I think you all are missing the boat if you ignore the flea powered triode amps......
