Audio Research DAC 9 digital converter

If you want to hear a convincing argument for the use of two separate DAC pathways for PCM and DSD, the DAC 9 makes it. The two pathways don’t sound materially different – both the digital design and the quality of the analogue output stage prevent that – but each brings its own advantages to the mix. A DSD cut of Led Zeppelin’s eponymous debut album of extremely dubious provenance gives a studio-like energy and dynamism that even a copy of the first pressing of the LP cannot replicate. Meanwhile, on the PCM side, transfers of well-recorded CDs and high-res downloads of similar quality deliver the goods in a similar effortlessly dynamic and detailed way.

Audio Research’s Foundation Series DAC 9 is the latest in a long line of digital products, in many cases each one better than the last. That tradition is continued in the DAC 9, as this is the best Audio Research digital product that the company has ever made. The combination of a detailed, dynamic, articulate, and accurate musical reproduction coupled with the sense of timbral, tonal, and temporal balance of the product itself makes it a firm Foundation for your music. Highly recommended!
