LSA Voyager GAN Amplifier

I have never seen more bologna being thrown around outside of a bologna sandwich.  Entertaining it is but far from reality. 

@ricevs Give me a call when you are free. Some potentially exciting news for you about having a lot more ears on my modded amp.

ricevs, 
You said, "...the difference between bad sounding 38K resistors and great sounding 148K resistors (the brand of resistor and the impedance both give a sonic improvement....my source was 50 ohms high current capability....class A output discrete stage)."

Ah, the difference.  What you found is the difference in the quality/brand of the resistors.  What if you try the same high quality resistor for 38K and 148K?  That would address George's point about whether the value of 38K, 148K makes the difference.  I know you said you did this, that the value makes a difference, but it would be nice to evaluate technically with measurements also.  Ideally, the better sound should correlate with better measurements.  We need both the subjectivists and objectivists to have the best understanding of how we all can improve sound.  The objectivists need to do more listening, and the subjectivists should try to do more measuring, although even the smartest objectivists don't have all the answers.

George,
I understand your point about how 38K is high enough, which is similar to the interface principle about having the input impedance of a power amp be over 10 times the output impedance of the preamp or other source.  But maybe 100-1000 times is better than 10 times, as with my Denon 305 MC cartridge with its impedance of 40 ohms, having more HF extension and clarity going into a phono stage at 47K ohms rather than 400 ohms.  Is my analogy correct?

Different story with a mechanical/electrical source as MM or MC Cartridges, they need sometime none or lots of electrical damping, which in some cases can give the impression of more detail extension and clarity, maybe because of reduced bass output. As they do not have a mostly fixed output impedance like a solid state output stage has. We used to load down the Supex SD900 with 10ohms to get them to sound right.
Cheers George

George,
No, what I heard from 47K loading of a few MC cartridges into a few phono stages was more extended HF, rather than reduced bass which thins the tonal balance but doesn't yield more HF.
