It is worth every cent
If you just started getting into audio like me, definitely get this one, or the one from Schitt audio. They drives my 6xx just fine.

you could go from the headphone output of the PC to RCA inputs of the AMP and amplify the signal and it would work. But typically the output off a PC soundcard is sub-par, dirty and clearly not hi res, so you'd be amplifying a dirty signal. That's why its recommended to put a DAC between the PC and Amp

IF $100 is your budget limit, it's a nice amp. Very clean and quiet, decent detail, not much in the way of dynamic range. Definitely seems to be lacking in low end punch and extensions. Mids/ highs good. Coming from a Yaggi DAC into this. Using Senn. HD6xx, Audio Technica ATH m40, and HiFiman 4xx's. Drives all acceptably. For under $100, I can recommend, if I had spent around $200, I would be disappointed.

Why buy the 220v option and then leave a bad review when you havent used it? You should take this down..... When you buy there's an option in the page for which voltage version you want.

I think he’s saying that he ordered the 230v version but got a us plug? Still don’t think it’s that big of a problem to get a same spec power brick

I've been using this amp for the last few months to power multiple pairs of headphones that I own. The three main pairs that I use are the Sennheiser HD598, the HD6XX and the Hifiman HE-560. The amp itself seems to have a pretty low noise floor, as even plugging in pretty sensitive IEMs doesn't transmit anymore than a tiny amount of noise, if any. The 598's do sound a bit more open, and although this isn't a huge difference, it is pretty nice since these are my headphones of choice for playing games, especially positional audio games like CSGO. The bass response of the 598's, which isn't necessarily lacking, definitely sounds stronger when hooked up to the O2. The 6XX sounds pretty amazing with this amp. Obviously this isn't a headphone you'd typically want to run without an amp anyway, but it pairs very well with the O2. Compared to listening to them through a non-amplified source like a phone, the only real way I could describe it accurately would be to say it feels like the 6XXs almost "open up" as if they were removing a shroud that was covering them previously. Everything sounds more clear, more powerful, and the channel separation seems much better too, although that could be placebo or simply the combination of being able to hear more detail. The HE-560s are probably the most power hungry headphones I own at the moment, and despite the O2 amp only putting out somewhere between 300 and 600mW at the 45Ω impedance and 90dB efficiency, it sounds amazing. Bass hits hard (as planars should), the treble is clear and sparkly, and mids are warm and enveloping. As much as I'm sure the 560 could take more power from a bigger amp, I have trouble parting with the money to buy one since it already sounds so good off the O2. Bottom line, this is a phenomenal purchase, especially at <100$, and I'd highly recommend this amp to anyone. I'm actually thinking of getting one to put on my nightstand for use when I don't want to have to sit in my computer chair to enjoy my music!

Could be a grounding issue? I’m not an Objective 2 expert, but if possible try using different RCA input cables, see if a better connection helps with the popping and cutting out.

The perfect simple amp with plenty of power. 0.5 ohm output impedance - a great reference amp! Highly recommended.

You can not beat the price for what you get. I havent heard too many amps in my day I'm no extreme audiophile but I've definitely started to become one in the past year. I absolutely love this amp and it made my music much more clearer and louder than my Sound Blaster Z card was doing and I paid the same price for that. Highly recommend!

This is a great starter amp when paired with a quality entry-level DAC. I currently have the standard gain model paired with the standalone Massdrop SDAC and I'm really blown away with how much it has improved my laptops audio. I have it driving my Hifiman HE4xx, Sennheiser HD6XX, and my AKG K7XX and it does a wonderful job running all three. I have a Massdrop CTH to compare to and I can say that with a good DAC it greatly complements that amp.

Not sure why the love for this amp. Every source I run through it sounds muddier with a reduced soundstage. Pretty disappointing. Much better quality just plugging straight into the Grace Design SDAC or any other original source. I don't have any high-impedance headphones, my HD 598's at 50 Ohms are the "most" demanding, but all I hear on them is more volume and less quality. Perhaps if I get higher-impedence someday this will have more value? Throwing in the closet of misfit toys for now.
