I used the same trick for my Equal Opportunity phono stage. I stole it from Bruno Putzeys's paper on grounding. Very effective!

It's actually easy- keep the loads equal and the balance will be automatic and pretty damn close to perfect.

Measurements.

I did it on an AP analyzer. Either your unit is broken or you have a measurement error.

There's a reason for that. This isn't "Audio Superstition and Storytelling Review."

Don't worry, no-one else has, either. It's one more thing in the realm of "we can measure it and use it as a proxy for engineering...

First off, a heartfelt THANK YOU to this forum and it's members. I came into ASR thinking I knew something about Audio fidelity...

The problem starts with the basic concept: instead of using resistors and capacitors, which are close to ideal, they used inductors...

OK, at this point, it's clear you're doing a leg pull.

Please correct my math. Use equations and numbers. :cool:

If something is flat within 0.1dB (the vast majority of engineered amps), yes, it is perfectly flat. The rest of the handwaving excuses...

There's no excuse for not using basic controls. None. You either trust your ears or you don't and need to have lots of non-auditory cues...

100% of the time, shops will "coach." I mean, this is their livelihood. Last time I was at a shop that did a comparison, in this case...

Likelihood of an actual controlled test at a shop- zero. It's easy to do a test yourself. It takes some free software (Deltawave) and...

If you think so, demonstrate it. Do a level-matched comparison, ears-only, basic controls, and show that you can distinguish them. So...
