I have yet to do a side by side comparison yet since the DACmini is burning in as we speak, but both, IMO, play way above their pay grade. Both have excellent dacs & both have at least very good amps & both have RCAs out to my powered speakers & the speakers sound really, really good from either. My 1st comparison will be to compare these two against one another both as dacs, amps, & dac/amps over the weekend. My gut tells me that the mini is a little better based on what I'm hearing out of my speakers, but given the price difference, it ought to be a little better. I can tell you the HDP is one great piece of gear & it alone allowed me to get rid of 4 or 5 other dacs &/or amps I used to own. I promise to report my own observations as I have a real chance to compare them.
Great I look forward to it as the 3 amp/dacs im trying to choose between are the DACMini, HDP and Burson HA160D.
I have a gut feeling the dacmini may be the ticket as my source is going to be usb through my computer.
IF anyone has heard the ha160 and the dacmini and wants to chime in id be interested also.
