You need a power conditioner with multiple duplexes that isolates the digital duplexes from the analog ones and does not alter the sound much. Like this:

I have a Chang Lightspeed conditioner similar to this one on my HT equipment and it does not limit current, does a great job with isolation, and has no detrimental effect on sonics.
I had and sold a $3500 Furman IT-Reference 20i power conditioner on my HT (the Chang did a better job for me on music) and currently use a $5k Synergistic Research Powercell 10SE in my two channel system, so I am no rookie with power conditioners. The Chang will do the job for you and it will not hurt your sound.
I really doubt you will find a better solution any where near your budget.
