I got the chance to buy the edirol UA 4FX for a 100 USD is that any good, I am just wondering what i can use it for.


Is this an amp or what exactly as I am confused, will it be able to drive, I have it connected to my amplifier Yamaha RX V357 that is connected to my desktop.


When I use the volume out I chose the UA 4FX, although it improves the sound but will this benefit anything for if I consider heavy to drive headphones
