Great little budget amp... Better options nowadays
Really great budget headphone amp. Solid construction. Can't really recommend this in 2024 onwards since there are far better options (These are a very old design) I would suggest the Atom from JDLabs or the Magni Unity with a built in DAC. Very good amp though, sounds great and can drive almost any headphones

Great for unusual setups
I connected the amp directly to the stereo outs on a Denon DCM-380 CD change and it works extremely well. It drives my ATH-A900 headphones effortlessly. At low gain, I only have to turn the volume up to the 8-o-clock position to get at a high volume that is still comfortable to my hearing. Beware: this amp (when paired with a good DAC like the one on the Denon) will highlight all details of your music collection, even the flaws in the final mix and master.

Reliable Amp
I used this for 4 years and it worked fantastically. No complaints at all. I just needed to be careful because my Senheisser HD600 cord would get snagged and tug on it. It made the jack loose but overall it still works great.

Didn't come with an RCA to JACK cable
I mean, they've could've just added a free one, was so happy when I got it and then couldn't use because I was missing an RCA into JACK cable to use on my PC. Quality wise it's good. Don't know if it's just mine but I do hear a pop noise from time to time.

Worked well.... when it worked
Overall i would say this was a good amp it lasted as long as my hd 6xx headphones did about 2-3 years. I do have positive and negative experiences with this amp due to the loud popping noise it would emit. Never could figure out what the problem was. I also felt like i was cleaning corrosion off of my battery terminals on every 9v swap. But I give it 3 stars still because it was a good amp when it worked producing a quality audiophile for my Sennheiser hd6xx's. I would not be able to recommend this product because of only having owned 1 of these and my experience based off reviews I've read may have been a fluke.

Nice and Powerful
These supply more than enough power for my cans, however I do not recommend buying these at $95 as I believe there are better alternatives at similar prices such as the Atom amp. However I bought these on sale for around $50 and at that price these are a steal.
