Pros: Small, USB powered, solid 2V output, noise-free, sounds clean.
Cons: No RCA (on my version), no Toslink/Coax.
Disclaimer: This review isn't based on NwAvguy words and/or the stereotypes arround the ODAC. You won't see me using the words "transparent" and or "clinical". I actually gave the thing an honest listen, compared it with what I had arround me and this is the review I came up with.
 
Now, you might ask me, why did you buy the ODAC? Well, I wanted something small that I could strap under my computer desk and forget there. That's it.

But how does it sound?

Silent. This thing is completely silent. When I sit next to it in a quiet room, It doesn't talk or scream to me, which is nice. Ok now kidding aside, where as my E10 was picking up EMI that I could hear easily on louder than normal listeneing levels, now I can max out the volume and I can't hear a thing (with no music on obviously or my ears would be bleeding), which is really good in my book. Now, how does it sound with music on? First thing that striked me: the details. Bad recordings now sound terrible and good recordings sound terrific. I'm not talking about 24/96 "post-modern alternative on the verge fusion" jazz here, but well recorded 16/44 albums from Supertramp, Mumford and Sons, Muse, Jason Mraz, Maroon 5, Pink Floyd, Radiohead and so on. The sound is well laid-out and no part of the frequency spectrum jump at your face. I like that.

Now for a little comparison. My dad has a Bifrost on his fulls-size speaker system, so I replaced it with the ODAC to see if it feels any different, I asked him. We listened to Jazz at the Pawnshop songs where we can hear people moving their glass of whatever they are drinking arround and talking in the background. Our conclusion? He and I can't tell apart each DAC.  Both sound really good, and that's all what really matter. Now, please don't ask about our methodology or whatever. This wasn't a scientific test and we didn't have any expectatrion or preconceived idea of the results. We just gave an honest listen and WE just couldn't tell the difference really on our setup. It might be worth nothing to you, and that's cool, but there you go.

Conclusion? For 150$, you get really great sound from a simple USB port. If you want more inputs and flexibility, look elsewhere.

Gear used: Odac, Bifrost, Valhalla, HD650, Grado SR80, dad's speaker setup.

Nice, many reviews said that ODACs are really great and can compare to some other expensive DAC in sub $400 category. I read few comments and the owners said Bifrosts are just better than ODACs a little bit.
My combo is ODAC-> C421 OPA 2227 and HD598 but somehow it makes me feel tied for long times listening or maybe I do not like HD598. Maybe I will try other headphones. It is time to buy a new pair of headphone but the problem is money ha ha ha.
Thanks for the review.

Thanks for the review man. I just got mine, it certainly is better than my built-in soundcard. I agree, if you want more or specific I/O's this is not the DAC.

500+ Head-Fier
Pros: Tons of juice, good punch and control, beautiful midrange, dead quiet, good looks.
Cons: Nature of tubes, heat.
I used this amp mainly with a pair of HD 650 and it does what it is supposed to do: it has way more power than I need, it's quiet and it makes everything sound in its place. I have never heard other tube amps before, but I didn't get the "lushness" or the "tubey" thing , at all. It may be there, but it's just to tell you that if it is there, well, it's subtle. To my ear, this is neutral. I have no idea why exactly or how to explain it, but it has a "better" sound to me, more control, than my previous Fiio E10 and Aune T1 for what it's worth. Overall, a really good sounding product from my experience and I'm still enjoying it as much as the first day I got it.

Now for the bads... Well, if you ever thought about buying this amp, you are probably already aware of its "downsides". They don't lie on their website: this thing gets toasty. After a few hours, the volume knob gets really hot to the touch, but I don't care really. It takes arround 10 seconds for the amp to work when you power it on, and it takes like 10 minutes to completely power off. Tubes makes sounds (clicks) when they change temperature, but again, I couldn't care less.

If you read the previous paragraph correctly, you will understand that there is no real cons to this amp. In my book, this thing is a winner. It has the looks, it has the sound, it's made in USA, its 350$ and it has a killer warranty/customer support. 

To be honest, if you asked me why I bought this amp over let say the Asgard 2 (or any other amp really), well I had a good price on my unit at the time as it was opened-box and the Asgard 2 wasn't available (and it ain't still) in a Canadian retailer. Would I buy the same amp today? Maybe yes, maybe no, but I would probably get a SS like the Asgard or a Violectric because they are more versatile. But do I regret my purchase? Absolutely not. For it's intended purpose, to power my HD650 on my desk at home, this thing gets the job done with flying colors.

The Valhalla is one of the best amp for the HD650, much better than Asgard (IMO).
