Noticed a significant difference in sound, clarity, and soundstage with the ph1 morrow phone cables over the ones I had hooked up. Granted the ICs I was using were lower/midgrade but I honestly didn't think I would notice any audible difference. I definitely don't think I would go up to anything higher in the Morrow line because I'm not sure the cost increase would mimic the return. Using the BJC ICs for the preout to DSP and from the DSP to 1500. I may test out the morrow cable just to my LCR channels and see if there is any improvement there as well. Like Axiom they have a return grace period to test them out. I'll post here the results just in case anyone is curious.
