I have been flip-flopping over the years trying to figure out which part of the audio system is its 'heart'. Meaning, which component is the decisive part that makes or breaks the system.

Naturally, I was swinging from one extreme (the source) to another extreme (the sink, that is, speakers, their positioning, the room and its treatments).

Finally, reached the conclusion that it is nether of those. Of course, it is important to obtain the best possible source, as it is to obtain the best possible speakers and position them optimally in a well treated room. But even if you get to that point, the sound quality may still end up being substandard. So what is it then that is the most important part?

In my experience, it is the middle kingdom -- the phono preamp (for analog) or the DAC (for digital).

You could have the best possible turntable, tonearm, cartridge, cabling, preamp, power amp, speakers, room etc. But if your phono is not up to the snuff, you'll end up listening to grainy, hard, dry and unpleasant sound. Same goes for having the best digital transport with best cables etc., if your DAC is substandard, the sound will be harsh and unpleasant.

I think you may have nailed it there Alex.
Thinking about it both phono stage and DAC have to deal with very small signals without messing them up, plus keeping all the phase information correct.

Only if there is something wrong with the DAC. I'm not saying they don't vary in quality but providing we are talking about the DAC as a whole unit and not just the DAC chip, IME the poorer ones just sound a bit two-dimensional, 'cardboard cut-out', they paint in thick strokes. But they don't sound harsh or unpleasant. Harsh and unpleasant means something in the system is not working properly, or the amp is clipping, or the amp is a very poor design.

My thoughts too

Speakers can be harsh more than anything. But yes it's all important. Dacs vary enormously imv

Cables of course!

The size of the cable hole in phono plugs so that cable strain is minimised........Lol

The amplifier is obviously the 'heart' of the system because this is what 'pumps' the required power out of the signal (the blood) into the speakers to get music out of them.
