I have a NAD T-773 and JBL Studio L890 does bi-wiring do anything and what do i need to bi-amping and does it matter?
Heavy metal system need an impact, high current drive and narrow sound stage (so sound come direct at you, more fun!). I can't help you here as I don't know any AV amp (apart from my one) but the more transparant speakers are the brighter it's gonna be with many nu-matel recording so Ikon 6 may be over kill!
I have Ikon 6 and they sound wonderful with acoustic music. Possibly a little slow for heavy metal though.
System: Unison Research Unico CDE, Leema Tucana 2, Kudos C2, AIAIAI TMA-1 Studio Young Guru.
Joel they don't when you bi-amp them with some monster gear as I have. They sound amazing, transparent and fast now.
