Looking for clean power
As an alternative to what Rives suggested, i would suggest checking into large isolation transformers from Xentek or Topaz. These units typically have FAR superior specs to the Equi-Tech models, even Equi-Tech's more expensive "Super Isolator" and...

Geoff: Thanks for the info. I'll have some of these markers tomorrow : ) Sean> 
What is the optimum rca digital cable length?????
Sean: One should not need a network analyzer to compare the results of various cables with a specific transport / dac combo. A decent quality scope with a high quality test disc containing multiple test tones / waveforms should allow one to visual... 
Smoking from my amp?
Replace the fuses with fuses rated for 50 - 60% of the original value. If you have 5 amp fuses, use 2.5 or 3 amp fuses, 10 amp fuses would call for 5 or 6 amp fuses, etc... If the amp powers up and the fuses for that channel don't blow right away,...

Geoff: How can you tell if one marker color sounds better on a disc than another ? If you are applying a permanent marker, you would either have to use some type of solvent ( probably a big no-no ) or have quite a few copies of the same disc. Can ... 
What is the optimum rca digital cable length?????
This is a tough one that i'm currently working on trying to solve for my specific systems. I will only say that if the transport is exactly 75 ohms, the cable is 75 ohms and the DAC is 75 ohms, any length of cable is fine with the shortest length ... 
Best bi-wire speaker cables under $1000
Voodoo: I would pull the second set of speaker cables off of the speakers and take measurements with a single cable and jumpers hooked up. You can then hook things back up and take another set of readings with the complete bi-wire arrangement. I s... 
Best bi-wire speaker cables under $1000
Depending on the design of the speaker, the individual cables used and how the amplifier loads into the various combos, i wouldn't say it was impossible.I'm guessing that this is what you experienced when you tried bi-wiring with no other changes ...

Herman, Viggen was right. We want optimum performance, so asking an optimologist would be our best bet : ) Don't worry Viggen, those big medical titles always confuse me too : ) Sean>

Good info Herman and thanks for sharing. I wonder if these "optical enhancing treatments" are actually a "clouding agent" or "coating" as you mentioned ? By that, i'm thinking that it might be possible for them to apply just enough of a "blocking ...

Capeguy: I don't want to make it sound like i was challenging Audioengr or anything like that. What i was trying to say is that there are different design approaches and that nobody can design a product that will work universally well when dealing...

Buscis2: I posted earlier findings about the experiments that i did in another thread. For some reason, i can't find them when doing a search in the Agon archives. It basically details the same experience that i sent you via email. As to your offe... 
Why is balance in my pre inaccurate at low levels?
Marakanetz: Bias helps to minimize the "knee" in the gain curve of a device. The less bias that you have, the more apparent the differences in gain are between devices. I work with Class C amps all the time and the gain curve on these is more like...

First of all, speaking from a purely technical point of view, you did nothing to dispel any myths about digital. You simply gave us your list of what you think works and why you think it works. I just wanted to clarify that the contents of your po... 
Why is balance in my pre inaccurate at low levels?
Either the gain on one of the two channels is not linear or the volume pot does not track linearly between the two channels. Given that it is a tube based unit, unless you've got relatively new tubes that were well matched to begin with, the probl...
