looking for upgrade suggestions - 12,000 to spend

Chris, I would say upgrade by adding a turntable to your system. 12,000 smackers could get you a great turntable and LOTS of records. This is, of course, just my opinion.

Please listen to Professor Campbell! Oh, and raise the ceiling to 10'. (That should finish off the funds.)

Look Boss it's the "ROOM" Tweak the room and electrical. This is the biggest bang for the buck. Period! Your equipment is at such a high level of performance, that anything else would be small improvements as compaired to the "ROOM"

Good Luck

Great posts. I just finished wiring up four dedicated AC lines using cheap 10AWG for the monos and Belden 83802 for the digital and pre/tuner low current ones. WHAT A DIFFERENCE in treble purity and low-level dynamics!
A cheap no-brainer while you squeeze the room around....

Those Dunalvys either need to be replaced or modified. These speakers in stock form are NOT the "ULTRA" high resolution speakers that many audiophiles think they are. "ULTRA" high resolution will only be achieved with the best drivers and crossover components, and unfortunately, this is where Dunlavy skimps in his designs. I know of quite a few Dunlavy owners with SC-IVa's, SC-V's and Althenas. All of their speakers have been substantially improved by putting individualized zobel networks across each driver (a very cheap but effective mod, at less than $30.00 per speaker). Stan Warren of Supermods actually started this trend. Others have gone steps further by replacing that cheapo tweeter with a world class tweeter like the Morel MDT-33. (Shame on you Dunlavy for using such a meager cheapo tweeter!). You can also swap out those average Coils and Capacitors with some high quality parts. All of the above changes yield a much improved speaker that will have you wondering why Dunlavy has not implemented any of these no-brainer improvements himself. Once these changes are implemented, the speaker goes to a completely different level in musicality and listenability. We are talking about serious improvements here!
