Summary: Understand that this is written prior to actual testing, but subjectively this unit does everything I wanted it to. The equal-loudness contour uses the separate control method a la Yamaha (i.e. it's not coupled to the volume control), and after using it I now prefer it that way.

Summary: The old model we used was discontinued (Gemini 7000). After a long search to find a replacement I discovered this unit. Almost and exact match, nice heavy duty construction and it seems the controls are a better quality then the old unit. I guess time will tell. All in All very nice!
Summary: It's a cheap preamp that sounds OK but has no headroom, it clips the top 3dB - The low-cut switch is not a subsonic filter it's a major low-end cut like turning the bass all the way down. The loudness control is kind of wimpy, I would expect more high and low boost when it's fully clockwise.
Summary: I bought this and paired it with a Pyle PR2500/SEA2500 Channel Amp to run my three pair of in wall speakers and set of outdoor speakers on my porch. I had previously had these jury rigged to an old 5.1 A/V Receiver. This all works really well and is a lot easier switching between inputs.
Summary: Great pre-amp with very useful features, but as others have mentioned, it has a very low output. In fact, it does not amplify the input source (which is normal for a pre-amp), but it seems it actually reduces the source volume (which is NOT normal).
