Hi, would appreciate any thoughts or experience of this. My B&W CM4s are currently wired to my FMJ A22 using just single runs of cable (Homegrown Audio Silver Lace braid from www.homegrownaudio.com ). I'm very happy with the sound, but notice that it is possible to biwire as the A22 has two sets of speaker outputs. Does anyone have any experience of of this with the FMJ A22? I understand from reading other posts it seems to be on a case-by-case basis whether or not it makes much difference, so would be interested to hear from anyone who has experience of this particular amp. If it is worth it, can I use a thinner cable for the HF signal, something like the SC-3 or SC-4 braid from Homegrown? It would certainly save me a bit of cash. Thanks in advance for any help.
