Your obsessing too much confusing a decent amount of channel separation

with the actual nature of the signal, and acoustic results when we listen at home.

Even in a good say coincident even sound-field mike recording, the total signal even through n-speakers is STILL mostly mono. The difference signals are small and for us the critical factor is their mids and higher, in those channels so that we get a sound field. JBTW position is orthogonal to music. IE Phase, timing, and FR are aspects of the same signal not separate.

What I'm focussed on is how hard a system is working and how to make that as inaudible as possible.

This is a hobby about the small stuff, which is crucial, so maybe it's not 'small', eh?

Bass instruments still have overtones and they do more to tell us how they are played, and how they are being reproduced.

I bought the vertical argument and went with one channel of my modified LEAKS in triode mode. They have seriously large PSU's for baby valve amps at over 20 joules each. Then the designer of my speakers reminded me about how Linn/Naim systems were always done horizontally and that I should try it, even just bi-amped ones. S'nap.

Given their task and PSU reserves both amps were loafing (into an easy non-reactive highish/efficient and sensitive load.) Yet one way around the sound was a lot nicer! The only real difference is the task the PSU's faced. One had to work hard but we minimised its impact on the total sound. The other PSU whose impact on the total sound was empirically potentially far greater was having a very easy time.

The only valid distinction between vertical and horizontal as terms is that in one we ask each PSU to deal with the demands of a full range signal one supply per speaker, and the other we isolate each PSU to lows or to highs.

That is, a single PSU for each power amplifier is neither horizontal or vertical, no matter how many chassis we use or how they're wired, it just is multi-amped. yes/

I absolutely disagree and note that Kef did too in their manual for the spkrs. - Timbo in Oz 20:36:38 08/05/12 (1)

Did you try horizontal as well as vertical? - Timbo in Oz 08:03:58 08/05/12 (0)

There are very good arguments in favour of hosizontal bi-amping including only having ONE power supply working - Timbo in Oz 07:53:00 08/05/12 (3)

You do lose on isolation of power supply effects, which is kind of predictable.tble - Timbo in Oz 08:02:28 08/05/12 (0)
