The Law of Diminishing Returns Begins After This

September 17, 2013

If you're looking for a Headphone amp that will give you gobs of power, a great bass boost, small footprint, and ultra cheap pricepoint, look no further. JDS' cMoy is extremely well-built, boasts a long battery life and will power everything short of the most power-hungry orthos. Definitely a good place to start for headphone amps.
