Harmonious Audio MPA-1A mkII. Excellent head amp for moving coil cartridges. Absolutely silent, thanks to being DC battery powered. Recommended for MM tube phono stages, for use with a Low Output MC cartridge. 10 hours on it. I bought a Benz Micro Lukashek PP-1, which is 5 times the price and a little better. Save $20 from ordering this head amp online (save the taxes, shipping and duty). Made in the USA. Batteries included.
