Hybrid headphones / preamplifier

With its two 12AX7 valves, when used as a headphone amplifier, it produces the warm, soft yet precise sound that music-lovers appreciate so much. It manages the bridging as a preamplifier. Here it is an ideal addition to the SP-997 monos. Now there is a small, space-saving stereo unit for harmonious, open sounds.
