I use DH Labs BL-1 interconnects and Analysis Plus Oval 9 speaker cables in my Acurus 125x5 and Act 3 HT, and it sounds very rich and full. I chose these cables for their inexpensive price (I bought the Analysis Plus used and the DH Labs BL-1 new) and good sound and I have not been disappointed. I found a Tributaries sub cable on Audiogon for my sub, so it is the only other brand I have in my HT system. All very reasonably priced, available used, flexible, and resellable if you decided to upgrade.
