thanks, borg, for pointing this out. i feel badly for inadvertantly helping the perpetrator here. it's my feeling that, if a product is good, self promotion isn't needed - the word will get out.
the art di/o *is* a good dac, & even better modded. some day, i may try a stock art amp - not much to lose, w/30-45 day returns offered. (the thought had crossed my mind anyway, what w/the results i had w/the di/o). but re: modding it, i am sure it won't be long before art amps mods are out there in the public domain, & i will either diy, as i did w/the di/o, or hire someone a bit less unscrupulous.
regards,
