Thoughts on Tube vs SS amplification for Sony SS AR1s
atmasphere, I understand your point and the significant importance of the output transformer. In threads discussing tube amplifiers I consistently advocate the undeniable need for high quality transformers if one is seeking excellent sound quality... 
Considering the New Tekton Design Encores? AND Owners Group - Experiences/Questions
Jcarcopo,I realize that bi-amping is fairly popular but I believe that your perspective as it relates to the Encore is very rational. It would seem that these speakers don’t need it and are better off with a single high quality amplifier. Charles 
Considering the New Tekton Design Encores? AND Owners Group - Experiences/Questions
Hi jcarcopo, Thanks for the trip down memory lane as I can appreciate it thoroughly.  You discovered SETs earlier in life than I.  I went through the solid state amplifiers then tube push pull route for a number of years. My introduction to SET am... 
Thoughts on Tube vs SS amplification for Sony SS AR1s
No doubt that damping factor (DF) is an important variable that affects and influences the performance of an amplifier and speaker pairing. I have to imagine there are other factors at play as well. By every reasonable and trusted test bench metri...

jcarcopo,Very candid advice you provided. The Encore will most likely yield good/decent sound with most amplifiers across a wide price spectrum. I do belief that it will truly sing and display its full potential with very high quality amplifiers. ... 
Jazz for aficionados (removed)
It warms my heart to see appreciation for Dexter Gordon. He and Sonny Stitt  are two true giants of jazz saxophonists who I feel are not fully recognized.Charles 
???Anyone Here UpGrade From Yaqin/Cayin/etc... To Another Tube Amp Considered Hi End???
As devilboy stated in an earlier post "horses for courses". So true.Charles

You wouldn’t want your preamp output impedance to be more than 1/10 (preferably 1/20th) of the amplifier’s input impedance. Al’s correctly points out that some tube preamps have output impedances that can exceed that level (particularly at certain... 
???Compromise???
If the smaller/compact cooler running amplifier is very 'close' in sound quality to the larger hotter amp I could probably live with that compromise. However the performance gap would truly has to be quite narrow.I want to be able to enjoy and get... 
???Anyone Here UpGrade From Yaqin/Cayin/etc... To Another Tube Amp Considered Hi End???
I think that the Unison is a nice 'conventional' class AB/ PP design. They are a good company and I do not doubt their Triode 25 is a good sounding amplifier. If I were choosing between the two options I'd take "the leap"  (as David put it)  towar...

Freediver,Mastersound has a reputation for building their own high quality transformers. I like that the  Box is a pure class A circuit parallel SEP (Pentode el 34 probably wired for triode mode).   Weighs a hefty 53 pounds. I suspect it is  a wel... 
Best integrated up to $6000
Silverlakejim,Not at all surprised by your listening impressions of the two amplifiers. One is a solid/competent class AB push pull design utilizing indirectly heated pentode tubes. The other is pure class A, simple SET circuit utilizing directly ...

Hello,Looking at the level of the stated distortion and accompanying output impedance and damping factor of >10 (Does this mean But <20?) is consistent with a zero NFB (Or very low level of NFB). So based on these measurements they suggest t... 
Which one to choose between two 80K$ tube amps?
shkong,That’s quite a compliment you bestowed on the Line Magnetic 508ia. It has a well executed circuit and using 300b to drive the 805 output is a smart choice.. I believe this is an underrated amplifier with excellent performance/cost value.Cha... 
Ever feel like a "low dollar" customer that your dealer doesn't think worth their time?
oldhvymec,That's a good story. It just shows the importance of a little bit of kindness and  respect.  Charles
