Stereo receiver combining amplifier and tuner with audiophile-grade performance in a single chassis
Overview
The Denon DRA-350 is a stereo receiver from Denon's classic receiver lineup. The amplifier and tuner sections share one unit. Denon marketed it as "The Audiophile Receiver with the Performance of Separate Components," and built it for listeners who wanted a warm, musical sound with low distortion and strong technical performance. It uses a "DC configuration" circuit topology and a heavy-duty chassis. It has a reputation as a solid performer with a surprisingly good phono stage.

Design
The DRA-350 uses a "DC configuration" circuit topology, which minimizes phase shift and improves low-frequency response. The heavy-duty chassis gives it mechanical stability and cuts noise. That supports the claim of performance akin to separate components.
Market
The DRA-350 typically sells for $150 - $250 in good working condition. Common problems are right channel failure, intermittent distortion, and noisy power switches or volume pots. Maintenance means regular internal dusting, proper ventilation, and contact cleaner such as Deoxit on the controls. Service manuals are available. When a channel goes bad, repairs often focus on the output/driver transistors and ICs.
