Amp suggestions for Avalon Radian HC
Not a believer in cables ever except when I had Apogees with low low impedance.INstead of spending thousands in cables try a pair of cheap high current mono SS amp for the bass and get the dude to drive both the ST100 and the SS amps.$100 bucks sp...

Giving up already ? I had my ascents for many years before finally throwing in the towel. There are many great qualities of the Radian you will miss. 
Amp suggestions for Avalon Radian HC
I tried all sorts of audio research with my ascent ii.CL120, VT150, CL150, VT200, VT130 with and without mods. While they can drive full range with no clipping they sounded pretty unmusical. Not even close to acceptable compared against TRL s100 m...

Glad you still have the SA11. Take VERY good care of it as Dai no longer services audio gear.The Ming Da... keep it, there are ways to make the filament supply better, less prone to noise and less whistling. These things don't have much resale val...

California Audio Show 2012
Second Tholt's opinion.I was very impressed by the Acoustic Zen/TRI triode electronics 845 setup.Never heard ribbon speakers play strings that nicely. 
Budget Chinese Tube amps - any good?
I was about to post my rant and realized that Gopher's post exactly mirrors my opinion.And guess what? Those who went to the CA Audio Show this past weekend...the room with TRI triode electronics driving Acoustic Zen speakers hosted by Robert Lee....

You are running the ST100 in stereo/triode mode right?(Not sure what Paul's orig design was), the TRL S100 Mono I listened to was a DIY hand-held by Paul.Anyway in terms of solid state driving full range I'd say nothing beats the TRL Samson. A clo...

Tried all sorts of preamps during my Ascent days.The only preamp I liked was an MFA Lumi which I eventually cloned myself.Had a Ref 1 for the longest time when I had the Ascents as my main speakers. Open, quiet, overwhelming, and not musical.You c...

Most Avalon owners would have to use an RCA to RCA 100k trimpot right hat the input jack of the bass amp which usually has higher gain to attentuate the bass.I have owned Ascent II, Eidolon, and Monitor and have tried more than 10 amps on the Asce...

Radian HC means "High Current".Specially built for the Spectral amps.TRL S100 monos will be perfect for mid and high.Not for the 2 power hungry bass drivers in sealed box config. 
Best amp for Avalon
Radian and Ascents (I have the latter) are the hardest speakers to drive. Eidolon, Opus, and Ascendents are completely different.For Radians plan on using something extremely powerful like 300WPC for bass and something > 70WPC for the mids and ... 
Retubing an ARC VT100 mkll
Triode-wired tubes give a more refined sound. Richer in inner detail as many would call it. I would describe the sound as more linear, the microdynamics of low level passages are better preserved so you wont spent time hunting for the right listen...

Retubing an ARC VT100 mkll
No way the vs115 is triode. 4 tubes push pull per ch will not get you 110wpc even if you push B+ all the way to 550v.
