Hi
@Wladimir and
@Ravenor . Although I have talked about cable wire and construction at some length previously, may I just recap the main points I personally regard as perhaps of interest to those hunting for good cables - headphone
and, importantly, interconnect (analog
and digital).
After years of my own and other keen DIYers' trials in this area, concensus seems to be that :
1. By far the best wire to use is
mono crystal OCC (Ohno Continuous Cast), over 'ordinary' 'pure' silver or OFC copper.
OCC
silver being the best conductor is unsurpassed for overall performance, especially detail resolution and treble handling (less potentially harsh and sibilant than 'ordinary' silver). This enables a wonderfully open, 'clean' sound and more expansive stage.
OCC
copper is much preferable to standard OFC copper, also being very good overall but with slightly less 'sparkle' and crystal clear clarity than silver. However, it can impart a tad more bass/mid weight and body.
I personally have found that using
both covers all bases nicely, the copper helping to smooth performance especially in otherwise (over) bright systems, and adding to
sub bass delivery.
2.
Solid wire is preferred over
stranded, but can make for much less flexible/more wieldy cables - especially headphone! Solid offers less electrical resistance, therefore allowing for better 'flow' and less chance of possible slight distortion effects. 'Super' (expensive!) cables will in fact use
multi gauge wires...larger diameter for optimal
lower frequency handling, smaller for
higher. Fortunately in DIYing I've been able to apply this technique without bankrupting myself, and can attest to its efficacy lol
. But as headphone cable, I'm sure many wouldn't find its bulk acceptable...me?...
performance is paramount!
3.
Avoid silver-
plated or hybrid
alloy combinations...stick with separate silver and copper.
4. Re
construction, and applicable to
all cables IMHO (including coax digital!), I only ever keep pos/neg (signal/return)
separate...until the last section to ear cups for headphones. Along with expandable, flexible EMI/RFI suppression capable sleeving, slightly less twisting/braiding is then needed to minimise such distortion.
Obviously, the
ideal cable incorporating all the above is going to be extremely expensive commercially, but hopefully researching the manufacturers' specs may give a better idea of just what they're about, and their relative cost given how many of said qualities are covered.
Then, of course, personal trials (if able) according to one's purse is the only real way to see how they perform in one's own system, and to one's personal preferences.
So...GOOD LUCK to all who appreciate the gains from REALLY good cables, even if the wallet objects at first!!
...and a HAPPY CHRISTMAS to all lucky OG Empy owners.
