The Future of Audio Amplification
This entire thread is about perspective. Which throne do you sit upon? I am a former bicycle racer. Which bike is best or what is the bicycle of the future? It all depends upon your perspective. Michael Green would be all about e-bikes s'far as I ... 
Does anyone care to ask an amplifier designer a technical question? My door is open.
Well, it turns out that it was my friend Ralph (we have never met, I simply call him my friend) who misspelled Charley's name.   It is in no way an excuse for bad specs- and in fact our amps have some pretty good specs (if proper measurement tech...

Roger;I have not deleted any of my posts. Not a one.  fsonicsmith., you seem to troll my threads, this is not the first time I have encountered you. I think you are mistaken. I don't recall ever entering into any debate of any kind let alone som...

What causes a designer to choose a certain tube type for an audio circuit? Is the circuit designed around a specific tube, or is the best tube type found for the circuit that’s been/being designed? I know there are different electrical propertie...

This is a golden nugget of wisdom;(In their book "Control Design And Simulation", Jack Golten and Andy Verwer discuss (in chapter two) with regard to applying mathematical models to the real world: "...mathematical models invariably involve simpli...

I said I was done in this thread and once again, I lied. I swear this question is in good faith and not meant to challenge or make a point. While looking over at Tungsol's website I saw this; Engineers and musicians have long debated the question ...

Thanks Ralph. That means all the world to me. I know this sounds cheap and tawdry, but when I replace my Ref 150SE, I will be absolutely slanted toward an Atma-Sphere. Since I am still here and jabbering, I still maintain that the OP's stated goal...

Although we disagree on many things I do appreciate your Gentlemanly approach, unlike that other fellow who left us.Thanks - let's hope he stays away. His approach produces so much noise, its impossible to have an actual conversation, not to men...

 Preamps are much easier and to me not so interesting as power amps.From the heart, I don't want to tease you out and set you up for some type of audio sparring, a form of website f-erism I despise. I respect you and am willing to do my best to li...

Hears what JA had to say in Stereophile.. The Audio Research Reference 75 measures well for a classic tube amplifier design with a single pair of output tubes for each channel and a modest degree of loop negative feedback. Its output transforme...

Roger, I have two questions though the second is a doozy. 1) What do you think of the Tungsol KT150?2) What are your top 5 criticisms of the ARC Ref series components (i.e. the Ref 75SE or Ref 150SE amp and the Ref 6 preamp)?I ask because I own an...

They sound better or worse because they are poorly designed or built regardless of drive,To put it diplomatically, you are naive. As with all other components in the chain, no amount of engineering can do away with the flaws inherent in recording ...

I find this discussion interesting since I ditched my belt drive VPI's for idlers-a hot rodded Thorens TD124 and a Garrard 301. When I owned my VPI Prime, I heard a distinct jump up in SQ with the Phoenix Engineering Falcon and Roadrunner, but aft... 
The Cartridge and Stylus makes a big difference.
Been there, done that. The VPI unipivot arms are not a good match with Benz cartridges. That is just my opinion, naturally. I had a Classic and then a Prime and have two Benz Gliders which I used with both decks and then had them both re-tipped by...
