I like my Venustas, but they're single run. If you want a real bargain in a bi-wire, however, I'd like to suggest you keep an eye out for a PAD Musaeus. You'll get the same effective AWG (amount of wire) as in a single run of Venustas and therefore the same (or very close to the same) great sonics.
Opinions on speaker cable upgrade
I've been on an upgrade binge and want to upgrade my Acoustic Zen Satori Shotguns. Amp/preamp are tubed. Speakers are Von Schweikert 4 Jrs. If PAD Venustas were less expensive (and more available used), I'd go for those. I need biwired cable. Detail,and imaging important. I'd prefer hearing from those who are familiar with the AZ Satoris and/or the Venustas. Thanks in advance for all of your input. Budget is $1500 used.
