This was one of the best deals in preamps costing under $2,500 NEW. Very well made with really outstanding sonic ability for the money. This is the line version which has an additional AUX line input instead of the phono input. If you have a turntable in your system, you could always run the turntable through a phono preamp and into its AUX input. With other line sources, the DR-4 is impeccable in its clean, clear and transparent sound. Soundstaging was open and well placed. It may have been the “starter” preamp in the DR’s lineup but at almost 1/3 the price of the legendary DR-6 and easily 80% of its performance, the DR-4 was a sonic bargain.
Cosmetically, the preamp looks really nice. Minor scuff marks/nicks here and there but nothing major. We don’t have the original box but will securely pack this for safe shipping.
