I gathered from gossip in Meridian circles that Emperical do (or once did) a 566 modification. Is this true? How much does it cost? How good is it in relation to other common DACs such as the Perpetual Technologies (I also already have a PT P1/P3a modwright).
Mine is a 566.20.
It's on my website, although I'm not installing USB interfaces anymore. They are all external, except for the I2S interface. I would do the full mod (no USB) for $500. It is quite remarkable how it sounds, although a modded P-3A leaves it in the dust, particularly with upsampled data.
The hottest product right now is the fully EA modded P-3A (10X more mods than Modwright) with the Off-Ramp I2S driving it from the computer. Extremely low jitter.
