    Solid product. Comes with a mini usb cord as well as the power cable. Highly recommend. Was instantly recognized by Windows 8.1. Remember to disable to the ‘audio enhancements “feature”‘ to get the most out of the ODAC + Amp (personal opinion).

    This unit is a bit pricey, but comes with a few welcome upgrades over the standard version. It’s definitely a niche product, which explains the price, but you get confidence-inspiring build quality for your money. The nuforce uDac2 this replaces had numerous issues with noise, channel cut-out and general lack of stability. Static discharge would actually cause the uDac to stop working until it was unplugged and plugged in again. I didn’t do a blind sound comparison, but I wouldn’t be surprised if the uDac managed to have audible problems during playback (apart from those mentioned above). So far, this O2/ODAC combo has worked flawlessly.

    WoW is what explains this device. The bottom line is you can spend $1000 or you can spend $300. And get pretty much the same thing. I paired this with HE-500 headphones by HiFiman, plugged the USB right into my PC and picked it right up.

    I have not been happier with my purchase, I recommend this product over any AMP/DAC Combo. It even looks great, the rear power supply did wonders for this and 1/4″ port.

    Too many good things to say, I am so glad I found these people, it took me about a month to pull the trigger, I said NO way could a 300.00 amp/dac even come close to something like a Tube from Woo Audio. I was very very wrong, and glad I was!

    Awesome work Mayflower! Love your desktop mod for the O2 + ODAC combo. I think your version lives up to the spirit of NwAvguy’s goal for a desktop amp. The build and quality are excellent. The sound output is excellent. There’s really nothing more I could’ve hoped for.

    I ordered from Australia. Shipping was fast and well protected, and from order to delivery, took just over a week.

    Keep making products as good as this and I’ll be sending more money your way!

    Man oh Man! It has been such a long time that a product brought tears of joy quite literally to my eyes. Currently my headphones that I personally use are Beyerdynamic T-90s and I thought all this time the sound that was coming through was awesome….until I watched the episode of The Tek that had guest founder of Mayflower Electronics on the show. There was no way I was going to spend thousands of dollars on a product that would color the sound or not drive my headphones so yes I was skeptical at first, but if Logan says this guy from Mayflower has a product that he recommends I had to try it out and I’m so glad I did! The Objective2 with ODAC has a beautiful exterior it almost makes me laugh sometimes that such a small device can pack such great sound! Big Thank You! to The Tek and Mayflower Electronics for all that you do it’s honest people like you that makes the buying experience enjoyable knowing your getting a quality product!

    What can I say, other than this product is probably the BEST heaphone amp/dac you can buy. For any amount of money. I’m convinced this wont sound any worse than $1,000+ gear. I ordered an ODAC/O2 from JDS Labs a while ago, and I was quite disappointed when the volume potentiometer came loose and that basically prevented the whole amp from working. Instead of going through all the trouble to send it back and wait 2 weeks for it to be repaired, I decided to go with Mayflower Electronics. When I received it, the design was a lot better than the JDS labs version, and more sturdy. The volume pot was also secured to prevent loosening problems.

    I am extremely pleased and I won’t hesitate to do business with Mayflower Electronics in the future!

    Got these a little while ago…. and oh man am I impressed, I threw on my brother’s dt 990 pros and I was amazed compared to the little crap dac he has from fio. I did have a small issue with the sound going low on the left side and mayflower was super quick and responsive and had a replacement in no time. The support is outstanding and I will definitely recommend them to everyone I know.

    Why are you reading the reviews? Just buy this DAC/AMP already. I seriously doubt you will find a better product at this price range. I’ve tested this product with some studio reference headphones. There is no magnetic hissing with the AMP cranked all the way up, no gimmicky bass boost just accurate playback, and the construction is very solid.

    Troy of Mayflower Electronics is a great person to work with and his commitment to excellence both in customer service and product quality. He knows his business inside and out. If his products not up to his uncompromising standards, you won’t see it.

    I purchased my Desktop 02 w/dac (ver. a) a couple years ago. I have used it many times in many places and have always been pleased with it’s performance. It is solidly built, looks great, portable, moreover, it brings me a higher level listening experience to all the genres of music I listen to. Now, I am going to purchase a Fostex T50RP v. 1 modded headphone from Mayflower Electronics and look forward again, upping the quality of my musical listening experience.

    Simply amazing. My first dac/amp for headphones and it really does a great job. I compared it to Sennheiser’s HDVD800 on a pair of HD800. There is a difference, but it is very small! I can only recommend this product.
