To follow up on my earlier comments, I did try different power cables on the Planet 2000 the other day, using it as a transport. Wow - they make a much bigger difference than I would ever have expected. I was quite surprised. A transport just sends 0s and 1s... but something quite audible is going on nonetheless.
I tried these from my collection:
Analysis Plus Power Oval - good all around, a little more bass bloom than the others. Could easily live with it and love it - it's what I'd been using here.
Nordost Shiva - more detailed and quieter. Bass more tactile and defined, though with less overall LF output in quantity, but not lesser in reach (less bloom, and more true sounding.) Clearer, more articulate and impactful. This one gets swapped in for the next long haul.
Signal Cable Magic Power - respectable for the bargain price, but ponderously slow compared to the other two.
Mdp0430 - the Planet 2000 was "glue" in my system using its internal DACs, taming my Klipsch La Scalas with their sweetness. But as I've discovered, the same tonal balance is also achieved using the Bel Canto DAC with the Planet 2000 as a transport. Given the difference in sounds using different power cords when using the 2k strictly as a transport, it's clear to me that the inbuilt DACs of the Planet 2000 aren't the only thing that defines its unique sound.
I'm interested to hear your impressions of the DAC2, I may eventually do the same.
