I second that LME49990 is the best, the most musical and neutral of LME serie I don't know what was wrong, but when I pluged those opamp into the socket, those LME became too hot and there will be a lot of grain and noise so I had to turn off the DAC. So maybe burson

You can chose the option of downsampling in Jriver

dCS system for er ... 1 milion Obama (USD) Or MSB Signature DAC IV, fully upgrade + transport (~55 grands)

V-Link192USBV1.48.EXE Here comes the driver file... V-Link192USBV1.48.EXE

I just purchased this from audioadvisor... and without the driver CD ... Could someone kindly upload the driver CD, please?

Actualy, there are only two things that ya can swap easily: Tube and Opamp... Swaping tube is an easy task For opamp: the DAC25.3 uses 3 dual opamps: 2 OPA2134PA & 1 OPA2604PA As I know, many people say that the sound of OPA2604 is veiled off, easy to listen to, but lack of details... so if ya want to do a simple upgrade, just change those 3 opamps I changed those two OPA2134PA with 2 lme49720, still waiting for the DIP socket adapter so that I can replace OPA2604 with two LAM49710 (single)... As for the MKP cap... maybe we do need to solder those 4 as Lece did... just because Burson said that in theird 101 guide: stable DC current is important to draw the best of our op-amp module ... so solder MKP cap... BTW, just try to change some "reasonable" OPAMPs first
