Headphone Amp Inventory:
Scarlett 2i2 audio interface. Excellent DAC.
FLAC files as much as possible. Scarlett 2i2 audio interface, Harman Kardon HK 670 stereo integrated amplifier
Other Audio Equipment:
Dali 2002 speakers
.Tracks I test new sound gear with (reference tracks originally in FLAC):
Track is extremelly wide and deep (binural), easily shows when sound gear can't handle it in regards to width and depth, clarity in highs
Bass, mids, width and depth
The spotify quality doesn't do it justice but at the 1:17 mark a wave of bass and cello comes that is just a marvel of sound mastering, it will make me shiver played through good sound gear, and is an easy way to spot bad gear.
