Anyone heard the Scorpio?
Naughty naughty, you didn't SEARCH, did you? If you had, you would have found this http://forum.audiogon.com/cgi-bin/fr.pl?cspkr&1136849518&read&keyw&zzscorpio , wherein I called the sound from the Scorpios possibly the best-overal... 
6550 vs. KT88: What's different about the sound?
At $29 each or $65 per matched pair, The matching fee of $7 per pair is now reasonable. I recall a few months ago Penta was charging an UNreasonable matching fee, something like $20/tube IIRC.Warrantee is 6 months, BTW.. 
6550 vs. KT88: What's different about the sound?
1st, go to the tube asylum... http://www.audioasylum.com/scripts/tv.pl?forum=tubes&s=U ...and SEARCH there; you'll find a lot. If you decide on '88s, I recommend the Penta/Shuguang KT88SC. They're only $29 each and sound quite nice. I changed ... 
Tube amp recommendation for Gallo Reference 3's
The stories about lack of reliability are of early amps; the late ones are quite reliable indeed. The North-American distributor is in Canada and has established repair centers all over the US. ASL products are as reliable as any other vacuum-tube... 
2 stereo amps in a mono-block config = 2 x power?
Ghost, I know you're wrong but I don't know enough about it to argue your psuedo-science. Paralleling works. SOMETIMES bridging works, as in now having enough power whereas one didn't before.. 
2 stereo amps in a mono-block config = 2 x power?
Dan, there's lots of misinformation here and some good advice from John. But allow me to again* explain paralleling and bridging amplifier channels.Connecting the stereo amp's positive binding posts together and the negative terminals** together a... 
Multi channel preamps
TAS issue 160, March, 2006, HP's Workshop, part II, Equipment Notes, page 106. I quote partially: "...it brings something to my Super Maggie/Meitner system that had been missing. ... With the MET1 in the system, the flesh of the sound, the overton... 
Multi channel preamps
Copland makes a 6-channel all-analog tubed preamp, model CVA 306http://www.divertech.com/coplandcva306.html, that retails for $2800. C-j's new one, also tubed, the MET1, retails for $7500, and Harry Pearson in 'The Absolute Sound' just gave it a r... 
Tube amp recommendation for Gallo Reference 3's
Tonally I find them QUITE attrative without being colored...maybe it's that triode sound I love. I've replaced the 10 coupling caps per amp; mine sound cleaner throughout the MR and treble than they did before the cap change. They image quite larg...

Tantra, done anything yet?. 
Tube amp recommendation for Gallo Reference 3's
Tantra, since you already have 225WPC/8, and since you listen to rock and probably use every bit of those 225WPC farly often, I suggest Antique Sound Lab Hurricanes. They use 4 pairs of commonly available KT88 output tubes per amp for their 200 Wa...

What's the power rating of the NAD poweramp?. 
Better interconnects than Paragon within $800?
The new PSAudio XStream Resolutions, both copper and silver, got a rave review from Jerry Siegal at 10Audio.com. 1M pairs are $180 and $350.http://www.10audio.com/psaud_ref_trans.htm . 
KT-88/ 90 choices to replace my new stock tubes
The Penta/Shuguang closed-plate KT88SC @ $29 is still getting raves from users on the Tube Asylum. Mine sure sound good.http://www.pentalaboratories.com/product.asp?dept%5Fid=5020&pf%5Fid=KT88SC+SHUGUANG. 
Using Conrad Johnson MV60 or MV60s as mono amps
G, paralleling the channels of a tubed* stereo poweramp creates a single channel with exactly the combined power into half the individually rated impedance. IOW, if you leave an MV60's output transformers' taps wired for 4 Ohms as they are at the ...
