Integra Research RDC-7, 7.1-channel THX Surround EXT audio/video preamplifier/processor.
For sale is a gently used Integra 7.1 pre-amp/processor, in very good condition, selling for a very reasonable price of $495.00. I purchased the unit after it was upgraded by Integra, to use in a dedicated 2 channel, hi-fi system in my home. I have never used it for home theater...this is a dedicated, listening only system, that I purchased on a recommendation from an audiophile friend, and was beyond pleased with this processor in the time that I owned it. It has served me well for 5 yrs., and has been rock solid on all fronts, and really sounds outstanding. I powered my tower speakers with (4) NHT A1 amps in a bi-amp mode.
I am in the midst of downsizing, and selling off the more bulkier gear to pair down my A/V possessions. I am replacing it with an Integra DTR7.4, which I bought around the same time, and that too has a great unit, and will now fill the shoes of the RDC-7.
If you are reading this, then you are probably aware of Integra's stature in the audio world, and there are a fair amount of reviews on this unit in particular. Here is one very detailed review:

I would guess that anyone considering this unit, would be doing so for stereo operation like I have used it, and not home theater use (with the void of HDMI).
The MSRP for this unit when introduced (2003), was $4500.
