This amplifier is something very special, which by looking at it you would think it was just another mid-fi audio component of the 1980s. Yes the Silver faced receivers from the 1970's are beautiful, more popular, and much more in demand as evidenced by the crazy prices they are going for these days!
But IMO from experience the PMA-757 bests a lot of them in sound quality especially when it comes to playing CDs. I believe this case because inputs of the 1970s amps and receivers can not handle the higher voltage outputs and dynamic range of most CD players without being over-driven into distortion.
At the dawn of the digital age the smart engineers (with audiophile ears I suspect) at Denon realized this and designed the DAD (CD) inputs on the PMA737/757/777 series to accommodate and take advantage of CDs higher outputs and increased dynamic range!
Compared to my older Denon PMA-830 (even in direct Class A mode) the 757 just sounds clearer, more natural, and more musical without without a hint of distortion or harshness. My Denon Universal DVD/CD player has never sounded better!
To top it off the the MC phono section of the 757 also sounds amazing! It's perfect match for my Denon DP-62L turntable (which is same vintage as the 757) - DL103R MC cartridge combination! This has been my main turntable since purchasing it new in 1985 and the DL-103R never sounded right with any of the other amps/receivers I've used it with. I would bet the engineers voiced the MC Pre-amp section of the 757 using this cartridge and possibly turntable/cartridge combination. Perfect synergy!
Find one of these on the used market and you wont be sorry.

Great amplifier with a powerful, rich and detailed sound and the superb denon midrange is there!
Got my Technics CD player connected to it, it never sounded this good and I had this CD player for 23 years now. Also got a Kenwood KD-990 with a Denon DL-103 cartridge and the synergy is just great between them. So, a nice phono section as well as least with the Denon MC cartridge.
Highly recomended budget integrated amplifier

Incredible sound. I compare it with PMA-737, Yamaha AX-500, Sansui AU-3900, Marantz PM35 Mk2. All are good but anybody sound so good. I he adapted an DAC for a optical input.
For me is a top class
