after some problems with the first DAC2,i received a new one.What can I say? Unbelievable!!! Sound in general is more accurate,more dynamics,a better sound-stage......Perfect!!!! And in conjunction with the isolator and a good signal cable,it's a must!!!!
But most important is the support and the service that these guys gave me....truly professionals!!!
HIGHLY RECOMMENDED!!! PRODUCTS AND PEOPLE!!!
After about 2 weeks, got it today. Very pleased with the sound. Wow...!!!! More clarity and firmer bass. It has more air compared to the original SABRE USB DAC ES9023. Perhaps I should have bought it together with the Isolator, could've been a lot better. Ooh welll...., I think it's going to be my next purchase. Thank you thank you..!!!!! Five stars from me.
I just received this amazing Dac from the mail today and installed it to my hackintosh. I was using a Fiio E10 previously and this U2 sabre really sounds amazing. I'm an audiophile for almost 25 years and have spent most time listening to high end audio. Hackintoshers are always having problems on audio every time there is an update from apple and this is the answer by using this dac and its plug and play on mac. This U2 sabre has a huge and wide sound stage. music has good timbre and uncolored sound. Male and female vocal are excellent. I can hear individual instruments separated from each other including background sound nuisance. Bass are deep and tight and unobtrusive while the treble and high are sweet and airy. My speaker just dissapear in front of me and all I can hear is music singing. This is money well spent.
Excellent! Bought this DAC to use with a Raspberry Pi running piCorePlayer (to work as a Logitech Squeezebox). It already sounds LOADS better than the bog standard audio output on the Pi (even without having given the DAC much running-in) - gone is the annoying hiss when the Pi isn't playing any music - replaced instead with silence! And the sound is already far clearer when playing music. Can't wait for a couple of day's time when the DAC has had a good few hours of running in - I imagine it'll sound even more amazing then! For the money, it's a total bargain - it means I can buy a Pi kit and a Sabre U2 DAC for less than the price of a second-hand Squeezebox, and have it play right up to 24-bit 96kHz too - meaning I get performance more akin to a Transporter! Better still, it's so easy to set up - just plug in to a USB port on the Pi - no soldering required! Totally excellent solution for anyone who loved the Squeezebox and wants to emulate one on a Raspberry Pi!
Excellent sounding little jewel. Amazing quality for price. As compared to my harman/kardon DAC (Burr-Brown chip), this DAC provides much wider sound stage, much clearer mid-ranges and vocals, and much tighter bass. Noise is well-controlled, even when the dongle is connected to a USB hub. Definitely does not need an isolator if used only with headphones. The only range in which the DAC could potentially perform better is in lower high range, where the sound seems to suffer from some harmonic distortion. But this is noticeable only because performance is so consistent across the rest of the range. I confirm that it works on iPad and on the new Ubuntu 14.04 Trusty. On iPad you may get inconsistent behavior if you connect the dongle directly to camera connection kit. You will need an unpowered USB hub (any hub works) to get around the software limitation imposed by Apple that prevents third party devices to work properly on camera connection kit.
