DCM QED
A fair price for the QED's would be about $250. Your Yamaha CR820 will work just fine, though I encourage you to eventually get a pre/power amp similar to my own setup. DCM speakers do really benefit soundwise from better quality electronics! Enjoy! 
DCM QED
I am presently listening to a pair of TW's (52779, 52780). My third pair! RGR 4 preamp and GAS Son of Ampzilla. Speaker wire is Q Audio Time Stream (1980's). A real nice retro system I put together from my collection of vintage gear!  
DCM QED
The surrounds are rubber and should still be good! Early versions used Philips hexagonal frame 6 inch woofers glued into the baffles. Later custom round frame woofers replaced the Philips. Tweeters remained Philips mylar domes with wave guides (re... 
DCM QED
I worked for an audio store that carried DCM back in '78. The Time Windows ($660 pr) sold well. The QED's ($480 pr) weren't as popular - though they were basically 1/2 of a TW. And both sounded similar. Excellent pulse response - coherent sound - ... 
When should caps be replaced?
The Son has been playing music for 16 hours every day with no problems!  
When should caps be replaced?
@ ahidler: my 1978 Son of Ampzilla has been in daily use (always on - never off) for the past 2+ years! Still sounds excellent! So your vintage NAD 3020 and 3240 are probably ok too! It's anybody's guess how long caps operated within their voltage... 
Are Carver Preamps Any Good?
+1 sequimjim! I too have a C2 in my collection! An excellent, well made preamp that sounds fine! From an era when quality hi fi gear was affordable - unlike today! I also have a Phase Linear 400 and a TFM15cb - both very good amps! 
Amplifier for Sonus Faber Amati Homage?
You need a tube amp with output impedance less than 1 ohm for flat response into the Amati's varying impedance. See georgehifi's response. An older Audio Research tube amp might work. Why not try a hybrid amp like a New York Audio Lab (NYAL) Mosco... 
Tube question: any sonic difference in 6SN7 vs 6H30 vs 6H80 in the amp's signal position?
Try Sylvania chrome-dome 6SN7's from the '50s! 
Speaker Recommendation: 20K range
+1 soix! The new Carver ALS is a serious contender at $13K! A floor-to-ceiling ribbon array is indeed "amazing"!  
Cartridge for Symphonic music .
I added a new PLX1000 to my collection of TT's. Presently have a Denon 103R on it. Best TT under a grand on the market! 
Cartridge for Symphonic music .
Get a Hana SL mc cartridge (Shibata stylus - low output) $750. Add a Bellari SUT for $330 and you're within your budget! The Hana MC's got an enthusiastic review by Herb Reichert recently in Stereophile! 
My Amp is Broken - Not Sure What to Do - Any Recommendations?
Shame on ARC for telling you that your amp is now junk and not repairable! A company that cannot repair their own products doesn't deserve any customers! Find a talented technician that can get your amp going again. Surely there must be a compatib... 
Tube phono stage, or solid state,pre amp
See JA's test report on the Zu's in Stereophile. They were on the cover a few years back. 
Tube phono stage, or solid state,pre amp
Zu's have a tipped-up treble so they will always sound bright.
