If you need other items get total to $100 and use 25MORE to get $25 Off. I bought this amp, added a cable and a USB Charger I was wanting and paid under $80 including tax..Not bad.

I currently use an FiiO Mont Blanc-E12 amp to power my headphones. Would this Monoprice amp be an improvement over my FiiO amp?

How would you connect it to your PC? Most motherboards have "aux coord jacks". Would I get an aux-to-RCA cable?

Wasn't there an incredible deal on one of the higher end Cavalli models some months ago? Does anyone recall?
this was $165, most likely a price mistake

Yeah. Liquid platinum was listed at $160 and some got them for free due to a computer glitch, probably. I did. They also sent me a duplicate of another order.

Won't happen again.

This is a basic headphone amp with no DAC built-in and no digital inputs. So converted "crap in" and "amplified crap out"

I highly recommend the qudelix 5k for a portable DAC/amp. It's EQ feature is quite versatile.

Can you run a modern turntable into this and use it for headphone use only?
