Berkeley dac1 versus Esoteric K-03

My isolation is quite a bit simpler. Three inch thick maple platform on spikes on a Billy Bags table also on spikes to the floor. A couple of VPI bricks on top for mass loading and Herbie's Tenderfeet under DAC. Worked great on the Berkeleys.

Aha,Rja, I too find the mass loading and physical isolation (vibration reduction) to be very beneficial. It gave my digital a much more solid sound. Esoteric emphasizes this; but, they also emphasis the electrical isolation. On better units they use 4 or more transformers! I think if you try the electrical isolation/conditioning I mentioned the benefit may be much greater than the physical isolation, and bring a new joy to your listening :-) Happy experimenting.

Although I no longer own a Berkeley DAC, they are exceptional on HDCD playback.

Sanbhai what are "'the whole slew" of 'Superior' dacs?

Sorry Sabai. I'm thinking of dacs now. Also considering trying the lowly OPPO 105D; seems very popular and excellent value.
