I just received this directly from Apogee. I’m not an audiophile, but on my Bose 20 noise canceling headphones, the sound quality is now noticeably better. As source material, I’ve listened to AccuRadio, my own iTunes collection, and ClassicsOnlineHD. I’m not sure what the AccuRadio stream is, but iTunes is 256kbs, and ClassicsOnlineHD varies from 500kbs to 2000kbs, with an average of about 1000kbs. All sources sound much, much better. I’ve listened through a 2014 high-end iMac, and a 2012 Macbook Pro–and both sound equally good. I’m so impressed that I intend to purchase a second one, so I can have a dedicated Groove on both my desktop and notebook machines.
This DAC performs just as well as the studio converters …
This DAC performs just as well as the studio converters from apogee (Duet, etc…). The biggest thing you’ll notice is that the bass on all of your tracks sounds big (but not muddy) and the sound is noticeably clearer than your computer headphone jack output.
This Apogee Groove is the best sounding device ive ever heard flat out
So I have owned the Dragon Fly, Ifi Mini and various other DAC’s in my life. However, this Apogee Groove is the best sounding device ive ever heard. Its sleek and the build quality is top notch. As for software drivers, it works great with Windows using Foobar and sounds even better on the MAC using Audirvana! If you are on the fence just go ahead and jump over it into Apogee land. This device is flat out Amazing!
