What information do you want from me, and how can I provide it to you?
Thanks.
From backend to frontend, please let us know your loudspeaker brand & model + placement, especially if sitting direct on table without stand or Hi-Fi protocol obeyed, i.e. raised xxx number of inches from the table surface to avoid comb_filtering the response, and is it backed against wall? or plenty of air volume free space behind, ... may be a picture would be easier instead of all these writing.
Then amplifiers brand & model (this beginning to be not so critical) they are not perfect but they are nearly never as shxt as the source.
Next is signal type??? optical/coaxial (even less critical I think), unless analog then op_amps used by mobo are area for understanding their limitations. i.e. I'm sure my mobo isn't using one of those nice Burr-Brown.
Finally source = mobo soundcard or add-on soundcard brand & model or external soundcard brand & model. This play a big role I suspect, not only are the various IC have vastly different S/N ratio performance, harmonics or intermodulations, and various characteristic are completely different from one type to another, may be some still have jitter not as clean as expected unlike more recent soundchips. This is a bad ass that could make our sound different, not because it's shxt, just their tiny differences are amplified.
i.e. good amplifier vs not so good amplifier, from frequency response point of view, worst case +/-1dB (but usually 0.1 or 0.2) then harmonics 0.01% vs 0.1% - i.e. no big deal.... just 10 times difference.
While source soundcard brand&model_A S/N 90dB vs. brand&model_B S/N 120dB, in numerical terms, they are 1000 times different.
And sound card analog's output sometimes as bad as -2dB at 20kHz...... certain amplifiers too unfortunately
But ultimate worst link is still loudspeaker drastic varying frequency response, then coupled with radiation pattern or falling HF response, then past cone-breakup they go hay-wire, no longer having a pattern but random, so on and so forth.
OK, thanks again, just curious of various setup you guys are using.
Thanks.
The loudspeaker in this setup enjoys nearly no boundary obstructions to sound radiation outwards and suffers least comb-filtering and is best example, i.e. space below, behind and sides.
