Earlier today I had the chance to compare my stock ECD-1 dac to a Dodson dac (their expensice model - list around $8K) at Phil's place (Sonic Spirits). For the first time, I was able to hear some of the weaknesses Steve at Empirical has pointed out in previous posts. Specifically, the treble sounded a little unnatural and not fully developed, the soundstage depth wasn't as deep, and the sound did get a little cloudy and congested when the music gets complex.
Again, only when in direct comparison to the Dodson were the above wekanesses identifiable. I wasn't able to hear these weaknesses when I compared the stock ECD-1 to the Turbomod P-3A.
I am even more anxious to hear the EA modified ECD-1 at my place in a few weeks (Wolfy, you are bring the ECD-1 and transport right?). I am hoping Steve's mods address these issues and that it gets close to the Dodson.
If you have money I highly recommend you contact Phil and listen to the Dodson.
