My system is in a state of flux right now. Recently I began investigating speakers coming from a headphone background. I've tried the 6.2 cables on a Teac AI-301DA and a Schiit Mjolnir 2. The Teac is used as a speaker amp, but I'm unhappy with its performance so I have an Emotiva A300 on the way. The Teac, the Emotiva, and the Chane A1.4 speakers I'm using are for experimental purposes -- to see if the speaker thing is for me or not.
So, my best amp is the Mjonir 2 with a set of 1975 Reflektor Silver Shields, which is a headphone amp. My headphone reference chain is as follows:
Dedicated Audio PC -> Supra USB -> LKS USB-100 (I2S bridge) -> 1' generic HDMI -> Gustard X20U (I2S port) -> 6.2 ICs -> Mjolnir 2 -> Focal Utopia.
I have a Furutech GTX-D NFC(R) outlet dedicated to the amp and DAC. The amp (whichever one I'm using at the moment) is plugged into the outlet with a Audio Sensibility Testament power cable. The DAC is plugged in with a Lessloss Original cable.
