I considering the purchase of a Burson Conductor 3X/GT. My buddy ravines about his Burson, however his does not have the DAC. The circuit layout look very well done. The design revolved around there discrete opamps, that are surface mount components that plugs into a 8 pin opamp socket. The Burson can be used as a Preamp, Dac, Headphone with Balanced In and Out, USB and Bluetooth. So the surface it looks great. It is designed to play all types of high impedance phones.
My knock is the external wall wart 24 vdc SMPS.
Having said that, this is nice but how does it sound. My knock is the external wall wart 24 vdc SMPS.
