    Is the Audio GD NFB-11 (2014) a clear improvement over the EHP-O2 (O2+ODAC) driving an HE-500?

    Currently I use an HiFiman HE-500 driven by an EHP-O2 (O2+ODAC). The HE-500 is an awesome/crisp/highly detailed headphone but I would like to improve the amp/DAC part. My budget is not that big (max. 400€) but I don't mind buying second hand.   I've found the Audio GD NFB-11 to be an...

    JDS O2 blew an op-amp (pic inside). Question regarding replacement.

    I got out of the shower and smelled the oh so familiar smell of burning electronics in my apartment.  After some blood hounding, I traced the smell to my JDS O2 headphone amp.  When I picked it up, it was hot to the touch.  I opened it up and found this:       I ordered some new NJM4556AD...

    Beyerdynamic DT990 Pro + Odac and O2 amp?

    Hi! I just bought Odac and o2 amp combo and I began a search for new headphones to use with it within 200$ I was wondering, would DT990 pro sound great with that combo or will it be too bright? Are there any other headphones in this price range that can compete with DT990? Thanks! :)

    JDS Labs O2 amp

    This is the JDS Labs version of the popular O2 amp only. It has been used for a couple of months with less than or equal to 300 hours of use. I have made a recent upgrade to my audio system, so I am asking $95 shipped in the US for this item.  It includes the power cord, original instructions...

    JDS labs O2 or C5

    I know that the O2 is very large and is considered transportable than portable.    However I want to know if the O2 performs vastly better or just about the same but with more power than the C5 amp   And are either of the batteries user replaceable?    How long does the O2s battery last?

    Is the JDS O2 comparable to the Triad Audio Lisa L3?

    Has anyone done a side by side comparison?    I previously owned a Portaphile 627 which was said to be comparable to the L3 but I didn't find it much better than my Fiio E11.

    Sennheiser Momentum and O2/ODAC Issue

    Heat output: Schiit Stack vs O2/ODAC

    My PC runs 24/7 and even though I won't be pumping out music 24/7, my sound components won't be turned off.   Can anyone give me advice on which can handle 24/7 operation better? Schiit stack or O2/ODAC?   Thanks

    Quick Question about headphone amplification.

    This question probably has a simple answer, so here it goes. I purchased a pair of Beyerdynamic DT 660 headphones for listening to classical music. I simply have them plugged directly into my PC, and this makes sense since their impedance is 32 ohms. The product came with the 6.34 mm adapter...

    Soon to be Q701 + O2 owner looking for insight into sound cards for PC Gaming

    Alright, I've learned my lesson. I jumped on a set of Razor Tiamat 7.1's for $200 and quickly noticed the audio and bass clarity were not near what I was hoping. So I actually sat down and started doing some research, and I think I've hit a snag in some info that hasn't been quite discussed...

    Would I notice a difference in quality upgrading from Xonar DG to O2+Odac?

    I have a pair of dt770 pro 80 headphones, the DG can drive them okay, the volume has to be kind of high but they still sound good. I've asked about other amps before, but what I'm really curious about is the DAC. The Xonar DG is a 35 dollar sound card, while the j2labs stuff is well over a...
