effortless completely neutral sound, endlessly powerful

anent the OM error, which was my bad, just follow the graphic directions on the backplate I put mine on a cart also at this late date, best to turn it on-off via powerstrip, not the front rocker switch, which leave on manuf date is later 1980s, none being made in the 1990s be sure to check dc offset periodically I never noticed any flimsiness to the stiff fins, but possible I guess ... there needed to be so so much sinking lmk if you want some recent overwhelming test data (drmoran@aol.com) ... e.g., could not be tested bridged into 1z, for fear of harming the testing device (powercube)

A virtually unknown Gem. Clear uncolored sound and so much t doesnt run out of powe. . I ran the Large accoustats with a Medallion transformers and sound through them was more defined than than the X-amps (Tube ) that came with them. Not anything wrong in the full spectrum of sound bass was solid and defined and highs were crisp but not to the point of fatigue. I have big Krells , Levinsons and other and ths amp holds its own with all of them. Kinda ugly like a porcupine but after you hear it that thought all goes away. Never ran it hard enough that the fins got hot although it is definately a winter amp as you do feel the heat after a couple of hours of listening. No complaints dont overlook the CX 1 Preamp. My buddy got one from me and said phono stage rivals most stand alone stages he has heard. My summary is forget it being designed as a surround amp and use it as 2 channel (Be careful of connections aor use it in a Bi amp situation. Compared to the Levinson Proceed multi channel beasts i give the DBX the lead .

Hard to move Fins are fragile but having handles on both ends help

Fence Staining and Painting So beautiful!!

Good quality and nice look!!!

I have had this amp actually I bought 10 of them . I used this unit to drive my Martin Logan requests which is a difficult loads for a amp . This amp drove them with ease . I used. A modified Conrad Johnson PV5 nice combo . I still have one dbx1 left to sell.

It’s massive 90 lbs. hard to move. Note the owners manual is written incorrect on connections for two way it has a correction page make sure you check it out the Owners manual listed on line is missing this crucial page correction !

Powerful (512 watts into 8 ohms, 812 watts into 4) - smooth, quick, not dark, not brittle.... just right! A fine piece of work, made in Massachusetts. Configurable for 2, 3 or 4 channels - great for bi-amping, driving stereo speakers and one subwoofer or driving 4 channels of any surround system.

Hard to move around - put it on wheels!

A fine amplifier, I've used it for nearly 20 years to drive Apogee Duetta Signatures. It's smooth, immensely powerful and capable of driving difficult loads with ease. I bought it specifically to drive the Apogees because they're pretty demanding - below 2 ohms at some frequencies. It handles them with ease. With Adcom amps driving Hsu Research subs through a Rane active crossover the combination is very satisfying.

The amp is beefy though! Weighing 90+ lbs it can be difficult to move around. I have mine on a wheeled table. It can be configured for 2, 3, or 4 channels as well making it a nice addition to any high end surround system.
