1. I am attempting to connect my O2 amp to my computer to use my AKG-Q701 headphone. I don't yet have a sound card but am using a 3.5 male to male cable. Do I need to use a TOS cable or something as my audio player doesn't recognize a device there.   2. Is there another audio player someone...

Yes, this counts as mini for me.  I’m prone to rambling...   Since Lord Voldemort was kind enough to send me one of his Objective2 prototypes in return for being one of his loyal minions (or maybe just giving him some useful advice from a different perspective) I figured I should write up...

Hey guys, at the moment I'm in the market for a new pair of headphones, and I was looking at getting a pair of Grados, either the SR80i, or the SR60i. Is there a large difference in the sound quality between the two? I've read that the 60's are easier to drive, while the 80's sound much better...

I thought of moving into something decent and start by buying my self a ATM-M50 and at first i was thinking of going with the HRT Music Streamer II but recently i read somewhere that it does not do good when it comes to music with really fast dynamics. I listen to a lot of Metal so now i am in...

This was a fun little project i have been working on that may be of interest to some.  I recently built an Objective2 headphone amp with an ODAC in separate enclosures which had the unforeseen side effect of sucking me into the DIY electronics hobby. I then picked up an old Tektronix 2225...

Hey Guys,   Please be easy on me since this is my first post although I've been a lurker for years.    I had the good fortune (misfortune?) of sampling some audio gear over the recent months (JHA JH5, HiFiMAN HE-400, Fiio X3, and most recently JDS Labs Objective 2).   For all of us who...

Hi,   There seems to be a recent new addition to the HifiMeDIY Sabre line.   http://hifimediy.com/index.php?route=product/product&path=62&product_id=107   I want love to get some feedback or comments on this budget DAC, so please post here if you have any experience with this!  ...

So I could get an O2 for £90 which is like $139 for you American folks. Obviously prices of amps will vary in different country's. but from that price range, is O2 amp the best for a sennheiser hd 558 headphone, or should i look at other amps? I'm using a sound blaster titanium hd sound card...

4Good evening everyone! I plan to get my A1 recently for driving 250ohm DT990. Any recommended DAC for this combination? Thanks a lot for answering! My sound source is CDs and I have approx $500 budget.
