Amazing

This dac/amp combo will power any set of headphones you're likely to run into. Now I know very little about audio and don't claim to be an audiophile. Despite that this product has met my needs in every way, which includes heavy gaming and music use. Currently using the dt990 pros from Beyerdynamic, the 600 ohm version, and this dac/amp provides enough power for them. Though I do use the gain switch with them unlike my other headphones.

Objective2 + ODAC rev. B combo unit.

Pairs with an HD650 very well. Clear, uncolored audio & signal path, and ultimately a product I would recommend to anyone who wants a solid combo unit.

Objective2 ODAC Rev. B DAC & Amplifier

I thought lot and hard before purchasing this product. I'm not a gamer and was looking to enhance my music listening from my computer through my headphones. I've spent good money on some very nice can's so I thought a DAC Amp would improve my music experience. Like all things I spend my hard earned money on (never enough of) I research to get the best bang for my bucks. With the help from others that reviewed this product I decided to pull the trigger on this unit. Ordered it from Mayflowers web site, it arrived quickly and was very impressively built. Compact yet solid and it's performance is everything I could have hoped for and then some. Making the best out of all my can's all I can say is WOW worth every penny spent. Clean and powerful if your interested in one of these buy with confidence they make a world of difference especially with HD lossless music. Thank you Mayflower for a great product.

O2+ODAC

Ordered this during the holiday rush, and it was still received within a few days. It arrived well packed, although the volume knob fell off initially and had to be installed with an Allen key. Otherwise, the build is clean, tight, and attractive. My unit has the power on the rear and RCA outputs as well. Installation following the enclosed directions was completely straight forward. I use these to drive a set of modified Grado SR-80e headphones. As noted elsewhere, the noise floor even at top levels (with no input) is effectively zero. The sound is as good as anything I have ever heard, I'm going back to previous recordings to hear them again. You will notice hiss on older pre-digital recordings, otherwise the quality of the input will govern the quality of the output. I have used a much older DAC previously, this blows it away. If you have been looking for a DAC-Amp combo, you absolutely can;t go wrong with this unit. **HIGHLY RECOMMENDED **

Great amp. Great price. Brings Orthodynamic headphones to life which is surprising. It's stupidly powerful and sounds great. Almost no noise floor with the volume all the way up and the gain switch pressed in with nothing playing, you hear nothing. The DAC doesn't color the sound at all either. Sounds balanced and neutral. Great product.

I rarely write reviews for tech I buy but this one really deserves it. The O2 DAC/AMP gives you such a clean sound with literally zero distortion at even the highest volumes. I know that has already been said repeatedly but its true. I tried out the Schiit Audio Fulla but the amount of background hissing noise led me to return it. You won't get any of that with the O2. I've been using Sennheiser HD600s with the dac/amp and it sounds like a dream. Just remember the O2 Dac/Amp won't color your audio. Only your headphones will

Five stars, all the way. I have a pair of ATH-M50's, and compared to the audio jack out the back of my motherboard the are a couple things that can be said for an amp and dac combo. 1. Sound floor: Good clean silence. When there shouldn't be any sound, there isn't. At all. Unless I turn the gain to the highest setting there is absolutely no interference, and the interference that does come through is a result of my media software. 2.Frequency: Comparing this amp/dac to the 3.5 output on my motherboard, makes my integrated sound seem like a frequency muted and muddy listening experience. Keep up the good work. I definitely plan on buying more of your products if the quality continues to be this excellent.

This review is long overdue. I have the original ODAC O2, not rev.b., but rev b I would guess would only be better. This is a fantastic unit that produces clear uncolored sound to drive even high impedence headphones/sets at an excellent price. The build quality is excellent and the resulting sound solution is excellent. In addition to the unit itself though I have to give high praise to the support I received from Tyler Chilton. Service this good is a dying art these days. Tyler was endlessly patient with all my technical questions before and after purchase, answering email long after normal business hours. And months after my original purchase took the time to advise me on a good set of headphones to upgrade to with suggestions that didn't include any of the headphones he actually sold! He knew they we out of my price range and suggested some great options that have worked out brilliantly. I can't say enough good about Tyler, Mayflower, and their products and service. Don't hesitate, just buy from these folks! You won't be disappointed.
