Fosi Audio SK01 Headphone Amplifier Preamp

Little box of dynamite

After too much time suffering from an electrical interference issue at my home that made it impossible to enjoy vinyl records, I discovered that a headphone amplifier required much less power than my vintage Marantz or Pioneer receivers, therefore the resulting hum I was dealing with would be almost indiscernible. I run this SK01 through the FOSI BoxX2 tube phono preamp, then through a Numark stereo 10-band EQ for further tone adjustment, then ultimately into some Audio Techica M50 'phones. I couldn't be any more satisfied. A bonus: With the Numark, which has L/R level controls, I now have balance adjustment, too! If there is ever a "plug in" model of the SK instead of rechargeable, I'll be all over that one.

Solid Product at a Great Price

Great sound, with the tone controls and loudness options, plus portability make this my go to headphone amplifier. Well worth the money.
