Got bored last night and decided to try the Polk XM tuner thru my Benchmark DAC, via coaxial cable.
It's not a worthwhile thing----why? Well, although the music did sound better in alot of ways, flaws of the XM compressed signal were also highlighted; sort of a "double-edged" sword scenario. I also noticed the "Error" led flickering every now & then on the DAC w/the XM signal.
The built-in DAC/analog section of the Polk tuner helps to hide the flaws of the XM tansmitted signal---a good thing in this case...
Just an FYI.
