Denon PMA-50 Integrated Amplifier Review
Setup and Listening

ImageDenon, the longstanding electronics firm now owned by D&M, produces products for virtually every market. They also have prided themselves on staying ahead of the curve with new technologies, designing products stuffed with features at too-good-to-be-true prices.

Recently, I reviewed (and loved) the wonderful Denon HEOS distributed audio system, which was like a Sonos on steroids, and very affordable. The Denon AV Receivers are also superb, as are their line of high-end hifi components. This includes turntables, DACs, and network players. Last year I had the Denon DA-300USB DSD DAC in, and came away very impressed.

Denon PMA-50 vertical Denon has again responded to the market with an affordable, multi faceted integrated amplifier. Packed with features, the new $599 PMA-50 is basically a one-box solution, and is virtually future proof. The PMA-50's amplifier section incorporates DDFA technology from CSR. Its Class D amplifier is rated at 25 watts x 2 channels (into 8-ohms) or 50 Watts x 2 channels (into 4-ohms). This design is known to produce superior audio fidelity and high efficiency. I should note I reviewed a similar product, the NuFore DDA-100 direct digital amplifier, and found the technology very convincing, sonically.

The PMA-50 uses Denon's Advanced AL32 digital audio processing system, the same technology used on Denon's premium audiophile disc players and digital audio components. Advanced AL32 processing “upconverts, digitally filters and noise-shapes lower bit data to full 32-bits, delivering remarkable dynamic range and noticeably better low level resolution.” And, in order to reduce jitter, the Master Clock is re-generated in the PWM modulator.

The PMA-50 has bass and treble controls that cover an 8db range, and channel balance adjustments. The tone controls are defeatable as well, so they can be taken out of the signal path. A preamp/subwoofer output is also included. Most everything can be controlled by the supplied compact remote control. The PMA-50 is also a high-grade headphone amp with an adjustable headphone impedance control, with three settings for low, medium, and high impedance headphones.
