I have this amp that I paired with the SMSL SU-8 DAC and a Schiit Loki equalizer. I have listened to my Sennheiser HD800S and Audeze LCD-2 thru this amp and DAC, and both headphones sound fantastic to me with this combo. Has anyone played the Focal Utopia thru the AAA 789 amp? I recently purchased a gently used pair of Utopia’s (but as I haven’t received them yet, I haven’t had the chance to listen to them). Is the AAA 789 a good match for the Utopia?
