Some interesting things are happening in the world of DACs.

Now I can't seem to bring myself to even think about dropping $5K to over $10K for a DAC. But it seems LiPo battery power is providing a low cost solution to the power supply noise issue and making 'lower then low' noise floors possible for 1/10th of the cost of the heavy's. I've found that with our high sensitivity drivers, you can't get the noise floor too low.

Here's an article from Head-Fi regarding the topic:

The LiFePo4 Battery - A DAC Revolution

John Kenny's JKDAC32 has created a bit of a stir that others seem to be following, but he has just upped the anti with the Ciunas, a non-HiFace based unit that significantly improves on the 32:

So if you're in the same boat as me, and haven't dropped the big bucks on a DAC yet, then at around $725 USD, this sounds like a super bargain from a guy that "gets it". Since I only have the little Dragonfly DAC at the moment, and use that for my TV server, my order is in the queue for the Ciunas to use with my 300Bs and 604Ds when they're ready. Oooooo-la-la.
