Holy Schiit is the perfect word for this bad boy! After bruning for 100+ hours on the Uber upgrade it was total game changer. Couldn't be happier. Totally worth every penny I spent.

I currently own the Schiit bifrost without the Uber upgrade, and I truly love your review! I'm listening to all my 14 different Pink Floyd albums just to hear what I've been missing! I own the marantz cd5004 CD player, and I thought the Cirrus Logic cs4392 DAC inside was end game! Now that I own the bifrost, I'm also saying holy Schiit! SERIOUSLY! Again, love your review, and I agree with EVERYTHING you have stated about the bifrost! Excellent review thanks again! Oh and, I'm currently using the marantz cd5004 as my CD transport with the bifrost

Do yourself a favor. Get that Uber upgrade. You'll hear a night & day difference.
Trust me on this!!!
