I've used both of these preamps in the past. May I recommend something much better sonically in the Classe SSP30 or similar!?! Eithr that, or the likes of a used Aragon Soundstage, or even modest little Acurus Act 3!!
All of these units sound clea cean clean!, have tons of detail and clarity, and are simple to use. Also, the advantge of these units is that, besides sounding fantastic, will do ADVANCED BASS MANAGEMENT!...WHICH IS CRITICAL TO PROPER SET-UP FOR HT IN MY OPPINION!(this is Why Outlaw audio offers flexible bass mgmt processors).
Other great sounding pieces for a 2 ch/DD/DTS pre/pro, would be Krell HTS(no dirrect input however for Analog in's), and Proceed AVP. Both of these don'thave ABM however, and I don't think do dirrect analog thru-puts for Anlog in on CD, etc. However, I find you usually will still get better results using the Digital in from the DVD player and processing in the processor instead.
However, for money, flexibility, and features (minus the Analog thru's, is the Classe SSP30...great sounding piece, THX, ABM, etc...and affordable for new. Good Luck
