I have only had the cables installed since Friday so run in is not complete.
Comparing with Linn K400 or Ecosse ES4.45. The Ecosse cable is a bi-wire cable and I tried it using single runs of either the multi strand or solid core sections. In my current system the sound is cleaner and less prone to sibilance without dulling down the sound (Linn). Soundstage is the biggest improvement more depth and focus to everything with vocals especially being more out in the room and centralized. Bass performance is more defined with less overhang. Initially this can appear as less BASS until you try following bass lines and note the lines are easier to pick out and as a result have more attack.
The only issue (not really an issue I can find is the battleship build quality of the cable and plugs which require some space behind your rack and place a strain on cheapo binding posts (count the 875 in on that) found on some amps. The 875 cannot take spades only bare and banana plugs but I managed to get a fit so not an issue really.
One of the best bargains in hifi if you ask me.
Good honest service from Dave as well.
