How do tube manufacturers like VAC get 55 watts per KT88 where others get only 30-35?
Many ways of using this tube, Tetrode Ultralinear,Pentode, Triode in push/pull mode, all with different wattage results.Cheers George

More discrete R2R Mulibit dacs.
At some point in the next month I'll try to get some organized comparisons of the DAC with others. I'm definitely enjoying it in my home system. That'll be good to hear about.Cheers George

Amplifier Upgrade Decision
Aerial Model-7T They measured at 86db so they need a few watts, but also Stereophile measurements said they "drop to 3.5 ohms in the upper bass and low treble, and to 3 ohms in the low bass", so the need a bit of current also from an amp. To me t... 
Infinity IRS Betas

Using feedback to reduce distortion isn't a free lunch though, or is it? From what is understood for years by the guru's of amp design, is that any amp should be designed for as little distortion, low output impedance ect., as possible without... 
Is remastered mainly just less jitter?
dynamic range isn’t the only factor No there are other factors, but to me it’s the most important to start with and you can do something about it now, and the DR website let’s you be the controller of what you buy today.Cheers George 
Class D = Trash?
No but I believe from what others have said, the output filter in some Class-D’s is included into it’s global loop aiding it’s effectiveness? that's why I bought it up, just to cover all bases.Cheers George

Wow if this is right, stay away from the Audio-GD Singularity 19 DAC.Did these same guys do reviews on the Holo,  Denafrips or Sokeris?Cheers George
