I also live just around the corner from PS Audio in Boulder and (Johnkent3) I also recently purchased their new Stellar S300. I agree, it's a fantastic amplifier. I'm going back for the DAC/preamp too. PS Audio is a great place to visit...the vibe is good and both engineers and sales people are first class to deal with. Their listening room is a treat, as too is hearing the history of the speakers in there.
