I have been putting a brand new Amber 3 through it’s paces. Was using a Schiit Gumby multibit so my current baseline might not be sky-high but after trying a number of DACs including the Yggy and some NOS Dacs, with modest gains/differences here and there, the Amber 3 has easily exceeded my expectations so far ... and this is with limited burn-in so far. My first impression is that the sound is spacious, open, detailed, and dynamic. Bass is very solid. One would not think its a tube dac. (it’s running into a Line Magnetic SET amp).
My Amber has their very new standard USB module - apparently based on JLSound’s I2SoverUSB vIII instead of Amanero. (Lucas wrote "USB - JL - Superb!" next to his signature on the sign off on the bottom of the specs/test page). My Gumby has the gen5 usb but I always preferred BNC SPDIF. But the USB on my Amber 3 is absolutely fantastic. And bonus points for fast, silent changes between various PCM and DSD formats (up to DSD512 native).
Very happy so far.
