The Solo audiophile award winning headphone amplifier. Add the PSU1 upgraded power supply for even better sound.
The Solo stereo headphone amplifier started life in 2001, has seen a decade of continuous improvement and on its way What Hi-Fi? gave it five stars, warning customers to “be prepared to buy it there and then” if they dared to audition it.
Made for studio monitoring, the Solo is often used in commercial editing suites where it captures edit points so elusive to other headphone amps. It was also supplied to the BBC, modified to accept PO 316 (BPO) jack plugs. It is best partnered with studio headphones — for a headphone amplifier geared to driving the most difficult hi-fi headphones see the Solo Ultra-Linear Diamond.
The Solo SRGII is the result of our “Green Solo” beta-test program, where over 100 customers took part. Where energy conservation is a must the Solo SRGII is the only high performance headphone amplifier in the running.
