I'm very happy with mid level Synergistic Research Cables, both the Tesla T3 power cables and Tesla Accelerator speaker cables. I have purchased these on the preowned market for reasonable prices.
Also, I might need a little electrical physics explanation about the current abilities of my ARC Ref150 tube amp. Specs list power supply energy storage as 1040 joules but max current is not listed. This appears to be less than 10 amps driving my CS3.6s with a minimum impedance of 2.3 ohms (below 2.5 over a wide frequency range). I have used much higher current solid state Krells and Bryston amps with my Thiels, but much prefer tubes at my comfortable listening volume. I can only hear distortion/compression above comfortable listening levels.
Also, can someone explain why power specs for tube amps are listed the same for different loads? Power output with my ARC amp (and other tube amps I've checked) is the same for 8 and 4 ohms. This really goes against all the talk here about amps that double down.
Thanks,
Jon
