Biwiring may soon be Constitutionally prohibited in some states.
yes, for a couple of years i did bi-wire with Opus......and maybe i'm responsible for this new state Constitutional Amendment.
the evidance
my second set of (12') Opus speaker cable i did purchase only 3 years ago; my dealer did give me a (relatively) good buy on but were i to sell it i don't expect to break even but who knows. i did buy my Opus 1.5m RCA interconnects used and likely could sell them at break even.
the Valhalla i have sold i got at least 90% of my original investment on.
i'm not a flavor of the month guy; and these cables have served me well in terms of overall value. i accept that there will ultimately be a net cost. Transparent and Nordost don't change their cables every couple of years; their customers typically get their investments protected as well as any expensive cables on the market.
the MM family of Transparent cables began in 2000; MM2 started this year (2008). i'd say Transparent has been reasonable in it's frequency of upgrades......so suggesting MM3 is around the corner is not really fair.
i'm not saying their cables have sensible list prices or that one can make a real-world case for owning Transparent.....but thats true for lots of esoteric products of many types. you buy it because you like it enough and you can afford it.
opinions on performance are of course a separate issue.
