Hi Rob - I'm using NVA LS5 speaker cable (bi-wire config) and for the pre-power & CD-pre I've some NVA Super Soundpipes. Normal Soundpipe for the Slee phonesa amp.
I've a 6m set of LS1 speaker cable that may be coming up for sale soon (if you or anyone else might be interested).
Richard'll be able to give you the low-down on cable/passive/active compatability though - it all goes way above my head! :)
