Digital question...


For audio out, my Panasonic TC-P65VT30 only provides for digital out; and, I want connect to one of the analog inputs on my integrated amp.

I tried the Gefen decoder and was not at all satisfied with the sound.

Would it be possible for me to use the Musical Fidelity V-Dac or the Cambridge Dac Magic as a decoder/converter to solve the problem. Thanks for your help.

The Benchmark is my choice with no modifications. However, I recently found this thread, http://www.diyaudio.com/forums/digital-line-level/70412-upgrading-benchmark-dac-1-a-25.html. There seems to be several threads here that boils down to changes in the capacitors, power supply possibilities, and op amp upgrades. In summary I did the following changes:
• LME 49720 to replace the NE5532s
• OPA1612 to replace the OP275Gs
• ELNA caps for the coupling caps
• Add a 10uf 25V tantalum capacitor on the 5v power supply (rather then changing 30 caps)
• Replace the 7805 regulator with a DEXA 70908

The op amps helped but the Dac Magic was still lacking in soundstage. Once I changed out the coupling caps and the 7805 the DAC was transformed. For the first time the wife factor used the word muddy and it was in reference to the Benchmark!! A $300 Dac Magic, with supposedly less then 5 hours of play time, and less then $80 worth of parts put a Benchmark (in use for 9 months) to shame. For listening I am using the RCA outputs.
