The VERY INTERESTING idea is that the introduction of noise as a dithering element for the analog signal (for our brain to decode) can be helpful in increasing the retrieval of information vital to conveying the Sound. Perhaps ...

Twogoodears,
I am sorry, I do not know what you mean asking me to speculate on these pictures. I know very little about ALE drivers and I would not make any guesses. The system design that is presented on the picture is certainly not of my li...

DA, looks like very nice and lucid assembly. How do you like the sound of the thing? The output stage 200mA /187V. It is a bit too small but I will do. I do not know what the gap you have in your OPT. If it is limited to 200mA then stay there, you ...

[quote user="steverino"]FWIW I got my own PP 1050 a week ago and am pleased with the sound. It is the first active device that sounds as good as or better than my jury rigged passive filtration. Thanks Romy. As for chaining devices, I tried plugging ...

This subject of digital crossovers became quite popular during last few years and many audio-people give up and go for a simplicity and painlessness of digital crossovering. There is an army of people out there who would swear by a complete transpare...

Actually I do not have the instability issue sorted out completely...I'm talking about circuit instability now, not the tube instability. Let us imagine all tubes are rock stable.As I see it there are at least two major sources of instability, in the...

[quote user="darkmoebius"]I asked Jim Hagerman how long it takes to break in interconnects, power cords, speaker, cables, and preamps? He replied - "Usually about 40-50 hours on a FryK. The amps are fastest and get most of the way overnig...

Here is another, simplified assault after some rethink and PSUD simulations.Rectifier: 3x1.2kV SiC per phase should do the job, actually 2 would do, but I'd preferto be safe. Bridge I don't want, as there would be 6 not 3 diodes switching1750V. 1.2kV...

Ari,
I do not think that we recognize the process of “audio designing” as the identical actively. It looks as you peruse to design an amplifier (for instance) as a conceptually well operating system where a set of deferential abstractly-measurable v...
