48 kHz Jitter Box?

I'm trying to clean up the digital music I receive from Cablevision as part of my digital cable package. The Digital Cable box sends the 2-channel audio to my Yamaha DSP-A1 digital receiver (which has decent onboard DACs). The stereo audio is encoded as 48 kHz Dolby pro logic.

For my stereo system, I use a Genesis Digital Lens and a Timbre TT-1 DAC, feeding a BAT VK-5 preamp. There is no comparison between the clarity and cohesiveness of my stereo CD system and the digital cable music. I figure (assume) the Cable box digital signal is littered w/ jitter and phase noise from its long journey, which manifests in digititis and distortion.

So does anyone make a jitter filter (ala Theta TLC or Monarch DIP, etc.) that can handle 48 kHz?
I believe the DIP handles anything UP TO 96khz.
Just about any 2 ch dac will handle the 48 signal from cable or sat. Any 2ch dac will improve this signal,including your Lense. It should lock on;no problem. (I had one years ago.) Most all cable boxes have a coax out.----- Or did I misunderstand your need?
The Genesis does not pass clock at all. It completely terminates the incoming clock and re-clocks using an internal temperature controlled oscillator. It maintains a significant buffer deep enough to absorb the clock differential. It performs some extra stuff on the CD multi-bit codewords. In any case, I don't believe it is capable of handling/processing anything other than Redbook @ 44.1kHz. I could be wrong, but that's the way I see it.

Not sure if the Timbre DAC could handle the Cable signal either. The signal is Dolby Pro Logic encoded. So I figure the DAC would need a built-in decoder. I don't think your average DAC has such a thing.

In any case, I tried some hook ups with my gear and got nothing but "rat-a-tat-tat..." noise.
