About synergy?

Yeah, I am the one who thinks that cartridge should be matched to speakers in addition to tonearm and phono stage. But it is a different kind of match, perhaps even more complex and subjective. And it doesn't mean necessarily that basic sound signature of the cartridge and of the speakers should be very similar. Depends very much on preference and music taste.
I generally agree that the best synergy can be achieved by mixing different brands though I try to stay with the same cable brand with the exception of power cords.

I have to say that to me synergy may be rather hard to quantify. For example, I have a Deja Vu Audio amp that I love. A while back I managed to pick up a used Deja Vu audio preamp at a great price and when I added it to my system the sound improved. But was it greater synergy? Or just a better preamp? Or perhaps a bit of both? So my advice is to experiment, and when you arrive at a sound you really like stay there. I have for about five years now and I find I am as happy as ever with my sound, especially after a recent retubing and cap upgrade, and I have I'm sure saved much money and stress getting off the upgrade train. Of course that train was much fun for many years, so ymmv. Good luck and happy listening though!

I'm really starting to hate that term, "synergy" as applied to audio. Misused subjectively. Prefer compatible and/or complimentary.

as has been said, it seems serious hobbyists have one goal:

achieving an optimal sound?

however, what is optimal for one may not be optimal for another.

there are constraints of budget and room, for example. there are many ways to achieve a desired result.

the important thing is to be aware of what you want. too many have no clue what they want, so the result is continual replacement of components.

decide what it is that pleases you and then figure out how to get there.

there is no road map. you're on your own. just listen, listen , listen, and learn.
