All I can add is that there is a HUGE difference between stock and modified. Albert Porter has sent his off to the same guy that modified mine for $140.00. The guy did all mods described at cfrasers site, minus the Class A mod, plus socketed the A/D chip so you can pull the chip disabling that circuit. He also placed the voltage divider internally so ANY digital cable can be used, as I'd like to experiment with better quality cables. I've heard both good and bad reports from those that have the Class A bias of the op-amp. I decided against it. After seeing what is done inside, I'd have to say that Waynes' price is more than fair.
vmps, art d/io, & boldercables.com
as many know, i am fond of vmps, & the art di/o dac. well, the vmps rm-40 has won a "best in show" award at the recent ces. and, here's a quote from vmps' brian cheney to wayne, of boldercables.com, who supplied brian w/a modded di/o. wayne charges $200 for these mods to the ~$130 di/o, & having done most all the mods to *my* di/o, i can easily say it's a most fair price! ;~) anyway, here's what brian had to say to wayne:
"...We used the DIO as our digital source throughtout the Show, since we thought the Sig 9 Muse player loaned to us did not sound as good. My transport was my own 10 year old Krell MD 10."
just thought y'all might want to know... :>)
