The Oppo HA-1 Headphone Amplifier is solidly built, easy to operate and features connectivity and flexibility far beyond its intended job of amplifying music for headphones. Yesterday's lengthy post revealed all of the physical, electrical and operational workings of the HA-1. Today, I would like to continue with some specifications, a discussion of formats and express my opinion on the "sound" of the piece...using some of my high-resolution, stereo files.
Specifications and Formats
The HA-1 is built around the same design philosophy that has made the Oppo line of optical disc players the "must have" machines among budget...and sound conscious...purchasers. Central to this philosophy is that build quality, flexibility, reliability and fidelity are company priorities...with state-of-the-art technology at reasonable prices. The HA-1 features the ESS Sabre32 Reference DAC. This is same 32-bit DAC that is used in the BDP-95 and BDP-105 machines and many other first rate DACs. It delivers uncolored, neutral-sounding, decoded digital audio from both PCM sources and DSD, as well.
