Sheesh, step away for 24 hours and BOOM… cables (and nervosa) rear their heads again.
So, here’s where I am at.
In 1990, I was deciding on an end-game setup (speakers, amp/pre, tt/arm/cartridge, cabling)… Once I settled on Apogee Duetta Signatures, I worked backwards, looking for best synergies at every step. I (fortunately) had a friend that was co-owner of an excellent high-end shop in Arlington, MA. So I could literally try a huge variety of components and cables.
And, I did… for months.
I learned that Cables (speaker, especially) back then… mattered (a lot). The best sounding commercial cables (then) for Apogees was Symo; but it was, to me, “unaffordable” (and this, at a time when the entire rig cost was around $16.5K!). I just couldn’t go there, despite the (slightly) better sound.
So, what did I do? At the time, I worked for Stratus Computer and we had this amazing “grounding wire” that was used to ensure common ground across the racks of the fault tolerant computer. It was 2 guage stranded, 100% copper! Yes, 2 - freaking - guage!… So I got a bunch from work (it was free!) and built up a bi-wire set of 2 guage cables, with nice spades…
And it was GREAT. I raced it with the Symo, and for all intents and purposes, it was 99% of the way there.
Later, after I got married and RL happened, I needed longer speaker run AND needed it to be attractive, so I got some AudioQuest Emerald, and ran in in non-biwire fashion. It was NOT as good.
Now, I’m back to those home-made 2 gauge Bi-wires. They’re ugly, but damn do they let the current flow to the Duettas!
So, my conclusions over 35+ years now; with too much tweaking, and in some cases fey-mods/hacks are:
1. Virtually everything DOES have a “sound” (synergy, or otherwise), but most times it is in the “noise/don’t care”
2. Bi-wiring matters for SOME speakers (my Apogees, and prior to that my Vandersteen), and not others
3. Top quality interconnect is MOST important from cartridge to phono pre-amp; elsewhere, “good enough is good enough”
4. Balanced for interconnects is USUALLY better
5. There is NO need to spend mega bucks. I will happily “race” my custom 2 guage set against ANY/ALL other cables in any system at any time. And, I bet they’ll “win” (or at least tie). (Note: they are UGLY as heck!)
6. Using iron chokes around interconnects SOMETIMES helps reduce noise floor; and I’ve found in many cases it’s needed between transport and DAC for digital cables (though IME this is variable based on the amount of environmental “noise” present).
Those who wish to (as I did for decades) mess with cable routing towers and other such… go for it… but it really is “diminishing returns” level IMHO.l
All above in my experience, YMMV.
So, I guess that puts me “in the middle”
