I use the NuWave DSD DAC with a USB input, through a Audience SE24 USB cable running to my Mac and Amarra. I also use the DAC with the coax RCA input, using a Transparent Audio Reference Digital Coax RCA cable running to my Oppo DVD/CD/Blueray player.
The Nuwave DSD signal is then flowing out through balanced interconnects to my Boulder integrated amp.
The only remaining source I have issues with is my cable TV terminal :
My cable TV terminal has several options for getting sound out:
1-Analog RCA: this is working great, but the way my system is configured and to gain better sound quality, I’d like my sound to go through the NuWave DSD DAC.
2-HDMI: This goes to a ceiling mounted projector. I do not use this for audio output.
3-Digital Coax RCA: I tried this audio output with the above mentioned cable that works fine with the DVD. No sound coming out when it is manually selected on the DAC and the NuWave DSD DAC does not recognize it when it powers up. The cable is good, it does work with the DVD and the DAC together…
4-Optical (tousling): This one is mind boggling. It is a new Silflex cable from Lifatec. When the cable is plugged into the cable tv terminal, I see its red light glowing on the other end where it is supposed to plug into the NuWave DSD DAC. So I know light is going to the DAC…This one, the NuWave seems to recognize briefly, but then goes blank. If I manually select it, it will stay on on this source, but again, no sound comes out…
I’ve been through several hours troubleshooting this with my cable provider, even with my Home Theatre techs and no one knows exactly what could be the problem. I’ve checked the cables on different sources and they work fine. The other sources themselves work fine. I rebooted the cable tv terminal several times with the HDMI cable unplugged, only the components inputs plugged in, no sound comes out of either the optical or digital outputs.
