I need help with advise on cables. I just picked up a used ANTHEM AVM30 and connected to my OPPO95. I am using a classe 300 for the two front channels and stereo ( I still really enjoy good quality stereo) and a classe ca75 six channel for center (2 bridged channels) and surrounds in a 5.1 set up. The HDMI goes directly from the OPPO to the TV (AVM30 does not have HDMI) and for now I am using coax for the connection AVM30 to the OPPO but I want to set it up for 2 channel with the 2 XLR out to the ANTHEM (direct mode) and with 6 RCA's analog out for movies using the DAC of the OPPO which I think will be better then the ANTHEM's. I have 3 sets of 2 older cables of the same length with RCA connectors, a Berkendorf & dresen 0.9L/3.0 50ohm set , a TARA labs prism set and monster cable m950I set. These are dating back to the stone age ( read stereo days) and certainly the first 2 sets were pricey. Can I use these 3 sets as RCA connectors for 6 channels analog from the OPPO to the ANTHEM or should they all be the same/upgraded? If a change is the way to go what do you recommend? Also, what XLR connect cables would you recommend for listening to direct stereo? Last but not least, the music from my NAS is currently streamed wirelessly via my AT&T/U-verse routers to the OPPO, am I loosing sound quality compared to hardwire cat5, if I were crazy enough to drill a bunch of holes through several walls and 1 floor ? Just curious. Thanks for any suggestions you may have.
