@jafant I've found that an old pair of simple AudioQuest (I think 4) cables sound the best on the 2.7 and DHLabs Q-10 sounds best on the 3.6. The rooms are also quite different. The 2.7 better damped and the 3.6 a little bit more live due to hard surfaces.
Another note on the ARC CD6 test. I didn't mess with speaker cables at all during that test - only interconnects. Thiel/Krell has never been known for soft/weak/wooly/uncontrolled bass so I didn't think to mess with the speaker cables. If I get the chance to test another ARC spinner I'll mess with speaker cables as well.
@tomthiel I've been looking for a pair of the Goertz cables to try however none have popped up locally.
