The O2 is a good amp. I like both it and the ODAC.
But unless you specifically need battery power/portability, for the same price you can get a Schiit Magni 3, which is three times the amp this is. The Magni 3 powers 2W/per channel RMS into 32 ohms, 1.3W into 50 ohms, 430mW into 300, etc. That's how many times more powerful? It's also a crystal-clear pre-amp. All that without losing any sonic performance. The O2 is a fine amp, and I predict it will always have a place among DIYers, but it's been completely and utterly outclassed at this price point, which is a good thing for all of us.

SlowCousinPeteIf only Schiit would fix their schiity shipping costs. $38 USD uninsured to get one to New Zealand, vs $9 from Massdrop here for this O2. :'(

SlowCousinPetePower isn't everything. I find the Magni 3 and O2 very similar sounding, whether you like one or the other is purely personal preference. My own leans towards O2, well at least with a HD600, it sounds a bit more colored with the Magni.

Nov 7, 2017

JackulaI'm surprised you can tell any difference in the sound. I consider these two amps to be about as transparent as you can get for the price. They both boast well below an ohm output impedance, so no difference there. Since I'm considering them to have more or less identical sound quality, what else is there to compare, other than differences in power output, and feature sets?

spronkThe Magni 3 + its linear power supply are bigger and heavier than the O2, so they would cost more to ship. I get that Schiit doesn't give you very many useful shipping options, but we're talking a difference of $30. Less than 30, really, after considering the size/weight difference. That may seem like a significant difference now, but a year from today, you're not going to remember what shipping cost or didn't cost. Buy the better amp

SlowCousinPeteWell, for anyone in New Zealand specifically, it means the Schiit stack attracts 15% tax and a $40USD customs fee because it's over the threshold thanks to high shipping cost. So suddenly a $200 USD stack turns into a $350 USD stack.
It's somewhat insulting, especially when I can go down to my local post shop and send a bigger box than the Schiit comes in right to Schiit's headquarters for $10 USD ;)
I'm not convinced that the Magni 3 + Modi 2 are worth that much more than the O2 + ODAC. Haven't heard the 3, granted, but I wouldn't say the Magni 2 Uber + Modi 2 is worth $150 more than an O2 stack.

SlowCousinPeteLots of things, noise, distortion, output impedance, phase. Also not talking about Magni specifically, but Schiit have a habit of using ei-core transformers which have cons of introducing large amounts of interference to other components in the same circuit.

SlowCousinPetejust joined this drop from Malaysia. A magni 2 here is MYR740. thats USD175. ordering from schiit website total about USD134(MYR566) including shipping, and any purchase we made online above MYR500 will be taxed another 10% upon arrival in Malaysia. Maybe we can avoid that tax but thats another story. Also have to consider the fact Magni 3 also has some humming issue , then we will have to consider the exchanging policy if we got a lemon. Meanwhile, this drop total to USD108 including shipping. And we can fix O2 ourselves if there is any problem. Maybe this drop is meant for international market haha.

Nov 8, 2017

spronkThat sucks, how does the O2 get to avoid that 15% tax?
IMO the Modi Multibit/Magni 3 stack ($350 in the US) sounds *significantly* better than the O2/ODAC ($280 in US), without costing much more. The flexibility of getting to use the Magni 3 as a preamp is very important to me as well, I connected the preamp outs to my Stax amp. I can switch instantly from regular headphones to my Stax rig, or to my loudspeaker rig in the future if I want to go that way instead.

SlowCousinPeteIn this case it's just particular to NZ, we have a threshold below which imported items don't attract tax. But other countries have similar situations too.
O2/ODAC should be less than $280USD no? From Massdrop at least it's under $200 for the O2 + SDAC separates. But I do get the additional functionality of the Magni 3 is nice.

Vote

Nov 8, 2017

JackulaI mentioned output impedance. Noise and distortion are well below the audible threshold in both amps, so I don't see how that's important. I don't know about the transformer-induced interference you mention, except that that doesn't seem to reach audible levels either, and I'm not too concerned about theoretical problems I can't hear

SlowCousinPeteOutput impedance, noise, distortion, none of those are fixed. Schiit's own measurements are referenced at 1V, that 1/12th of the amp's total output. You may already well hear distortion and noise, but do not perceive it because there is no point of reference. Good amps can cost a lot, cheap amps are not necessarily bad, just not as good. Magni 3, O2, both are superb amps for the price, I just prefer the O2.

Nov 8, 2017

SlowCousinPeteFor now Malaysia will impose 10% tax if goods is above myr500 or about usd120. Mayflower and jdslabs all are above that price for desktop configuration, not including shipping, which is at least usd20.

spronkYou're only paying $9 for shipping to New Zealand? Why the hell do we have to pay $13 for shipping to Australia then!

Dec 7, 2017

AdrianLI assume you are Malaysian. So if I purchase the O2 today, I will be paying about RM 440 with shipping to Malaysia and another 10% tax so about RM 500 ? If that's the case, this drop is definitely more worth it than magni 2 which is rm740 here...

Dec 7, 2017

AdrianLI will be using the Dragonfly Red as my standalone dac since I am using my One plus 5 with it. So basically my whole setup is semi-portable I would say.

AdrianLIt just kills the iPhone 7 or 8 in volume. It is that good.

AdrianLYup, but nothing compares to the LG v30. That one is just wow...

Dec 7, 2017

InfurnusXDyeah i can imagine. rm4k grey import. wonder when is it gonna be here. Apparently v20 also shares the same dac/amp and thats RM1500-1700. Worth considering

Vote

Dec 7, 2017

AdrianLI think it's already selling here for 3.4k. Try ask brightstar or directd, they would probably have it by now.

Vote

Dec 7, 2017

InfurnusXDyou are right. going for 3800 at directd, a bit over price for a 4gb ram phone. Making oneplus 5T even more appealing.

Vote

Dec 7, 2017

AdrianLI would definitely go for the 5t, it's only 2.8k and almost everything is perfect. But I have the 5 so I'm good with it.

Dec 8, 2017

AdrianLSince you have own the O2, I heard that you can actually fit in two 9v batteries inside. Am I correct?

Vote

Dec 8, 2017

InfurnusXDcorrect. though if you want to use rechargeable battery, it has to be NiCd due to the charging circuit.

Vote

Dec 8, 2017

AdrianLIs it NiCd or NiMh ? I got mix answers on which to use .

InfurnusXDMy bad. You are right it's nimh

AdrianLMy O2 just arrived Malaysia after (almost) a month of wait. Let's hope that it can clear customs and doesn't arrive broken.

Jan 10, 2018

InfurnusXDshouldnt be problem la. Poslaju not bad. Just received my Fostex T-X0rp from them today, too. No problem at all.

Jan 10, 2018

AdrianLAny Dac that you would recommend? I didn't see any SDAC that suppose to be dropped last december.

Vote

Jan 10, 2018

InfurnusXDmost dac other than on board is sufficient. I would recommend Nuforce uDac-3 if you do not have any dac. It only powered by USB, small, can use IEM with, has RCA out for O2. Not so expensive. Unless you are exploring DSD source, uDAc-3 should be good enough for entry.

Should I exchange the PC38X for better headphones?

I bought the PC38X headphones FOR GAMING and they are great, but I have NO use for a Microphone since I don't do competitive gaming and I was wondering if there were better headphone options at a similar price without a headphone, where (presumably) more of the cost was put into making it sound better. I also find that my PC38X don't get quite as loud as I would like and I was wondering if a cheap amp like the iFi Go link would draw a little more volume out of my phones. https://www.amazon.com/dp/B0BN6MM822?psc=1&ref=ppx_yo2ov_dt_b_product_details I went with the PC38X since it was considered the best bang for buck headphones. I care most about using spatial apps like DOlby Atmos and DTS Headphone:X. Suggestions are welcome.

Looking for a gaming/content audio setup

Hello! I'm looking for recommendations on audio setups. I'd be planning on using it mostly for gaming. Preferably I'd like a pair of large closed back headphones since I have a big head and jaw. I'd also like to hear myself through my mic with mic monitoring. As far as budget goes, I don't really have one. But under 600$ would be nice. I can go higher if needed. The audio setup would be connected to a high performance PC. Thank you in advance for any recommendations!

$10 Drop Coupon Email not sent?

Trying to buy some gear off Drop for the first time. I was told I would receive an email with a welcome to drop $10 off promo. I never received that email. Drop was able to send me emails for my login token and email for Password update. But for some reason the $10 off coupon was never sent to me.

New here

Hello, I just joined, primarily for the audiophile products. Looking at purchasing the NHT C3 speakers for our new living room. Space is about 15 feet wide by 33 long and they will fire long ways. Space is just for general listening, music room with all equipment is downstairs, so hoping they will fill it with sound nicely. Cheers.
