What tube amps for the Quad ELS 63

My small experience of old with 63's (10 yrs ago) both agrees with Detlof's &, strangely, agrees & differs from Frank's above:
-The small Jadis (now Defy7) gave me great joy;
-The Jadis 80 were my "reference" at the time; note that these were wearing ancient GE tubes -- I couldn't afford to re-tube them!
-Old Symphonic Line RG4 monos (ss), were at par w/Jadis 80 in driving, but I slightly preferred the sound of J80 over the S-Line in the upper mids (maybe due to my being accustomed to tubes)
-The Quad-Linn combo's I tried were... off (surely not only a matter of components synergy but also of set-up on my part)
- EAR 519 monos: good synergy & drove the speakers well
-The A-Research I listened to (the 150, I think) didn't quite involve me emotionally.
-Finally, Quad's own 45 (?) ss, sounded harsh

Note that during that time I was using a DNM6 pre with the power amps, only had a few cd's, and listened mostly to, and judged by vinyl.

Greg, the D-150 I use is the 1975 all tube model, not to be confused with the classic 150 monoblocks, which most definitely lack emotion. You know, the "better" this stuff gets, the WORSE it gets.............Frank

Gotcha, Frank, thanks. The AR model I refered to above was indeed a monoblocks version. Sorry!

I used Golden Tube SE40s with very good results. I intiially used a pair running as monoblocks, but then went down to one - it did the job just fine with less heat, electric, and replacement tube cost.

Your best bet with the quads 63 would be a conrad johnson mv125 amplifier. this is 125 watts per channel & the richness you get out of this amp. is quite musical & revolving. I am using this amp with maggies 1.6 & the sound is natural & musical. Good bass & imaging also. I have been involved in audio for over 38 years. I owned original quads in Ca. years ago. Good luck Marvf5.
