Need a quality Y-adapter for bi-amping


Where I can I find a quality Y-adpater to use for bi-amping? My pre-amp only has one set of outputs. Looking for something alot better than some inexpensive Monster cable thing.

Is it better to get a Y-adpater that I would fit my existing interconncet into, or is it better to just have new interconnects made that start with one connection and split immediately into 2 interconnects? Like a one meter long y interconnect (rather than an adapter). I hope I'm being clear.
Any help or suggestions would be appreciated.

Thanks.

I've used the Audioquests mentioned above, as well as those, which XLO used to market and some made for me by the Cable Company, also mentioned above. I also tried home brewed ones, which I soldered myself. None of them degraded the sound in any noticeable way and none was better or worse then the other.
The tape out can be used if you are feeding a powered Subwoofer with a level control .
When I was at Ambrosia Audio I noticed there was a cup of Kimber KCAG Y-cables. I also know that Harmonic Technology carries them and they also make customs. Audioquest also makes y-cables of each of there interconnects. There is less waste that way. They make them with the ends of the spools. Dale
