I participated in Light Harmonic's Geek Pulse pre-production campaign through indiegogo.
I ordered a Pulse X DSD DAC (dual-mono, dual full balanced) with the Femto clock upgrade and the internal amplifier upgrade. I also ordered the LPS4 external linear power supply.
Currently, I have a Yellowtec PUC2 LITE USB to AES adapter, powered with an Aqvox external power supply, feeding an Eastern Electric DAC, and I am hoping that the Pulse X will be a solid upgrade.
