I just listed an 8 foot pair of classic AQ Volcano speaker cables and an 8 foot pair of AQ Caldera here on Audiogon.

For anyone reading this thread after the fact, beware that the AQ Type 4 is an entry level cable with an aggregate wire gauge of 16. The Thiel 3.7 is a speaker that retails for $12900. Its impedance is under 3 ohms for much of the frequency range.

Therefore, both the Type 4 cable, and the XPA-5(which warns of a minimum load of 4 ohms, as does the XPA-1) are a bad choice for a speaker that presents this kind of load. I’d suggest not buying a $13000 pair of speakers if you can’t afford to then buy a more substantial amp. I’m sure a Thiel dealer could make some recommendations regarding the amp that would be a much better fit.

213runnin,I have 2 systems I use regularly,with over 25 k spent.Right now the xpa 5 will have to do with the rocket 44 wires.At lower volumes which I listen to it's fine.I got a deal on the 3.7 s so I went for it.I intend on upgrading the amp soon but right now I'm in the middle of a Corvette summer,because I can't drive 55!

Until they run out (and assuming your speakers will support it) I strongly recommend a shotgun bi-wired set of CV-8 cables from Music Direct. 

Consider the top line cables from Audioquest from several years ago. I bought SKY and Cheetah interconnects and they sound great and doubt that a new set would be so much better I would want to pay more. And they are often available on Agon for 30 to 50 cents on the retail dollar, depending upon age. And if you decide to do a change, they will still be worth much of what you paid.
