800 requests... How many does it usually take? I need this drop!
Illume
Same here! A combo of the new OL DAC with would be awesome.
I'm having trouble with one channel dropping out complete when using the amp (only getting sound in left headphone). Connect headphones directly to computer source and get both channels fine. Anybody have any suggestions?
Wow! Why hasn't this dropped yet?
should i expect any drop for this amp this year?
TaChouChiu
yes on friday
Just got mine. It doesn't seem to drive my DT880 600ohms very hard or particularly loud with the volume maxx'ed out. Am I doing it wrong?
Got mine today.
Very happy with it. Right now I'm using it with my well worn-in AKG K702s. The O2 drives them comfortably on the low gain setting.
I'm impressed with the build quality. With the batteries inside, it feels nice and heavy. The volume pot is kind of stiff compared to my other amps, but it's not a big deal. I don't notice any channel imbalance even at very low listening levels (Something that I have noticed on some fancier Alps potentiometers.)
Thanks to JDS Labs and to Massdrop!
Got mine. Thanks guys.
@jseaber I'm enjoying the new faceplate style. The finish is much nicer, with the beveled edges. I like that the ports are black now, (which I think is because the old part that was blue no longer exists). I'm a bit mystified at the switch to six point torx fasteners though.

@mohb: The genuine B2-080 cases include two sets of screws, phillips and torx. Some of our assembly guys prefer the torx screws.
We're in the process of switching to phillips, flush mounted screws.
jseaber
Oooh, flush mounts, that would be slick. Thanks for responding.

Products are ready to depart. Massdrop is still preparing this drop's orders.
jseaber
I can't wait!!!
i need ships to spain :(
Too me this doesn't seem worth it. It cost $129.99 MSRP. So why do you guys have it listed at $144.99 MSRP. The price should be lower in this drop. Can some explain to me plz ? http://www.jdslabs.com/products/35/objective2-headphone-amplifier/

Check the "Included" section of your link. This Massdrop deal is a bundled package. Correct value is $129 for O2 + 10.99 for AC adapter = 139.99 retail (29% discount).
So yes, Massdrop's math is strangely miscalculated by $5?!
I currently own an Audioengine D3. Would it work to use that for a DAC and the O2 for an amp? I'm worried about the D3 amplifying the signal before it gets to the O2. Not knowing how any of this works, I'm afraid of damaging equipment.
Anyone know how the build quality is on this guy? The feel of the knob (no jokes) and buttons/switches? I want something that feels solid.
bstro
The knob is very decent. It's made of metal with two rubber rings for grip. There's a nice resistance or drag to it so you won't accidentally drive your eardrum though your brain stem. The two buttons are good enough. A nice positive click for both positions. And the case itself is all metal. For its size it has some heft.
After owning the O2 myself and using it with lots of various headphones, I find it sterile and limited in soundstage so pairing it with The higher end senns won't really get you anywhere. Output isn't strong enough IMO to run planars I guess it would work with grados? Anyway, those wondering about the ODAC, it's also a very sterile and cold dac so it really depends on your preference

even order harmonics --> "If you're looking for color, by all means, odd harmonics from a tube amp will satisfy you more than any measurably clean amp."
NyquistRate
Correct, thank you!
Any chance of offering a Massdrop for the C5? I'd really like a C5...though I may just go for the O2 at this price instead.
imackler
@imackler: Our role as a vendor is to either accept or decline drops based on Massdrop polls.
O2 is a stronger amp all around. C5 is best for portable use with light and moderately demanding headphones/IEMs.
thanks.
Does this come with an A/C adaptor?
Mehere
Yes, a Triad WAU12-200 power adapter is included.
Sorry, we can only offer this deal in the US!
Mehere
Yeah it's in the title.
Just Feel sad for shipping to US only, I would want to get one of this....but I'm not live in US.
I would have pounced on this if it was the version with the DAC and if I didn't already have a Schiit Magni. For now I'll just worry about getting a proper DAC to better my sound quality like the above poster said... probably the Modi to complete my Schiit stack.
Ermannoc
If you add the dac later this is a far cheaper method. Soldering in the odac can't be that hard.
I though this had international shipping? Hopefully you'll still reconsider sending it to other countries.
Dang... I though it was the one with the DAC and considered it, but it's just the amp. No matter how good this is, it seems like it will compare with other headphone amplifiers: No better than input it's getting, just louder.
stevenswall
This depends entirely on the source. An amp like O2 actually does correct frequency response of audio players that have a high output impedance. And by presenting an "easy" load to your audio source instead of a difficult headphone, THD improves. Effective SNR also improves when listening below unity volume.
From the feedback we've received over the years, amps tend to be perceived as a greater improvement than DACs.
Canadian would be great
Shipping to Canada possible?
Is there any way to get the silver-faced option? I just bought the silver ODAC from JDS and I'd love the amp to match!
You can drop this Amp and buy the ODAC from JDS for less than the ODAC+O2 Combo... By almost 70 bones
Yeah... It says at the bottom that International orders will be shipped by Massdrop, but there's no options for anywhere other than the United States. No options for us Canadians?
I'm also curious. Is there no international shipping?
I use one of these for music production and mastering along with a set of AKG K702s. For my use it's perfect, I've got to say I don't have a lot to compare it to but I certainly don't have any complaints. As said above it doesn't color the music very much which can be a very good thing depending on your purposes. I was considering the above mentioned Schiit Asgard but after tons of research went with this one based on reviews/stats. Its also nice that it does have a limited battery only usage ability but certainly not a ton. I use mine plugged in nearly all the time.
Argh! I ordered one direct from JDS a couple of weeks ago. For those who are on the fence, it's a great amp at full price.
This amp is great on paper, and a lot of people will find it adequate. Some people will tout its superiority because it's "neutral" or "transparent". But after doing tons of research and trial/error, I've found it to be very clinical sounding. I like analytical sound, but the O2 just doesn't cut it for me. A little color to the music is usually pretty enjoyable, unless you're doing studio mastering. That's just my opinion, though. Only you can know what type of sound you like, but I happen to like a little warmth to spice up vocals. My Schiit Lyr gets me right where I want to be. If your budget will allow it, you're better off dropping $200 on a used Schiit Asgard, or $250 for a new Asgard 2. If you're looking for your first headphone amp and want to keep it cheap, then this will probably work for you. Again, most people will find this adequate, but I'm not a fan.
