John Curl's Blowtorch preamplifier

IF serious designers would take 'Blowtorch' ideas and apply them to typical consumer products, then I am sure that audio quality would improve in general. However, we have to fight, tooth and nail, just to get our ideas recognized and accepted at all, even if they are free of extra cost. That is the frustrating part.

...and after we won, there will be lot of followers who will not recognize us, like today trying to get a job in Internet and Intranet industry where I was one of pioneers, I am getting a strong resistance from gray masses. "How many years did you work with the application XYZ?", where all details of that applications may be learned in few hours...

What about connecting wire, fellow engineers?

Yea. It's always the s**ts when people have
ideas of their own

Do you mean something like Linkedin.com?

I have the right to remain silent.

For a few minutes, anyway.

You are better off running a wire from the middle of a board (if the circuit terminates there), than running a trace to the edge of a board.

This is sonics.. not cosmetic appeal of the innards - to consumers.

Trace design is another art.

Trace design is another art.

Could this be because of the effect of the manditory high-end ground plane on the signal traces?

Oh, nevermind, the nurse just came in to make sure I've taken my medication....

Ahhhh, now I'm on to it! It's the magical properties of the 8N grain oriented hyper-crystal wiring guiding the electric field that swimulates the signal transfer that I'm hearing. FR-4 really modulates the refractive curve!

Back to reality, electrons are stupid; if a wire sounds better than a trace, look around, don't punt.

Mike.

Postscript: I don't doubt that it sounds different, I just question the implication.

I like to use quality wire. The minimum is oxygen free copper with a good insulation. Quality silver is the best that I have tried so far. However, it is expensive, and hard to break-in, and even directional. Darn, what a hassle.

From my time in the military I 'inherited' many spools of mil-spec wire. Most of it is multistranded, silver-over-copper, Teflon insulated. I guess there's something better out there, but since I have this I use it and am happy with it.

One issue with multistrand is that the strands easily break at the soldering interface. That's why you always see it tightly strung up in military equipment. Not really diy-friendly. Is that the reason many prefer solid wire?

how do you do the break in?

pink noise/music/sinus/square ??

how much level?

on the spool or off the spool?

how much time is minimum?

with speakers break in is very easy audible, and i hear also interconnects or speaker cable sound for me better after apx. 100 hours in normal use, but i would like to know a technical method to do it to get them right.
