That's nuts! I got one of these for $75 last year and it was a great deal, $52 is a no brainer. Get it while you can, lads.

Very very great price! I ended up returning mine once I realized I would need something of higher impedance to drive my Sennheiser HD650 headphones (or maybe I didn't -- I'm not very educated yet on audio electronics) however these sounded amazing on my Sony MDR-V6 pair.

Also, if you have a red card you get an additional 5% off which puts it below $50 (before tax).

I ordered one... I have several other headphone amps so I'm not sure what I will use it for. Maybe this will replace my 1st gen Magni I stashed in my entertainment center. If nothing else the power button will be on the front! 😂 *shakes fist at Schiit for thinking a rear power switch was a good idea*

That aside, this is such a low price it's definitely "buy now, think later" territory if you could possibly use it for anything.

Been looking many years for a headphone amplifier. Only knowledge I have is from SD. But this seems cheap enough to be worth checking out higher end headphones. Bought one.

Anyone have experience with this for gaming? Debating between this and the astro mixamp pro that's $82 right now.. I've had the astro mixamp before and it sounded very tinny (like your earphones were in an aluminum can) although it helped with game audio. Was also pretty good use for media consumption
