what i want is: 1.opamps changed from stock opamp on main board to 2 AD825 on a seperate board (you figure out how!) with wires. this is the only comlicated...
Hi all, I'd just start to join this group. I reviewed DIO diagram and want to know several point: 1. How good the sound if we use analog preamp without Digital...
All- I'm a little surprised no one here's mentioned trying to use the tube buffered input as the output buffer on this DAC. I have no use for the A/D...
Tim, Agreed. I was going to go down this path of using the existing, non-used tube as an output stage which should be fairly straight forward. I just haven't...
Well, After looking at the design a bit more, it's pretty obvious why others here are so eager to get rid of the 12ax7a: that single dual triode just screams...
Folks, In my experience, power supplies have a huge effect on the sound of any electronic part. Given the incredibly lame power supply available for the tube...
I have access to 4 different DACs and the appropriately modded DI/O continues to hold up and not be the weak link in my true blue audiophile friend's playback...
Hi- I have decided to try the INA103 mod, and I have a few questions. I am a relative newbie, and I don't know some things which I'm sure many of you would...
... Sorry for the delay in answering - been away for a few days. Regarding the power for the INA103 chips, I just tap into the +-15v supplies that exist on the...
Hi Gary- Thank you for taking the time to respond to my post. I've hooked up the INA's, but it isn't working. I've been trying to troubleshoot the problem,...
I don't know if anyone has tried this before, it's hard to search the archives because it only does it small groups of messages. I know that there have been...
Hi Aaron, I think you might have ran in to the same problem I did when I did this mod. I initially thought i fried the chip, but after looking over gary's...
Aaron, I hope Huberts suggestion works for you. He's probably on the right track. I've modified a couple of DIOs this way, so it has been proven to work. If...
Hubert's got it right, I didn't notice that those pins were supposed to be connected. I had a guest this weekend and haven't had a chance to solder those pins...
Hi, Stumbled across some supposedly "better" voltage power regulators. What are your opinions about swapping out the stock DIO voltage regulators for these? ...
Hi, Who tried AD8065 op-amps together with 2SK170 in class A biasing? regards, Krzysztof J...

Aaron, I don't use any filter after the DAC. The oversampling digital filter inside the DIO puts the high frequency components relatively high in frequency...
Hello everybody, I've been a lurker to this forum for a while now, and I own a DI/O I have modifed quite heavily. I've kept only the DIG board from the...
Jean-Paul, Thanks for the fine write up. This board has been very slow of late, so its nice to hear from people with new information modifying the DIO. I've...
Gary, Providing separate regulation to +5V Digital and +5V Analog IS THE TRICK... The remains of my DI/O started singing after I did that. I am currently...
Here's a link to my posting over at Audio Asylum: http://www.audioasylum.com/forums/hirez/messages/184328.html Bottom line, I was bretty impressed with what...
Hi Jean-Paul, I ordered pair of AD8065 and I will try it next week, probably. I use since one year Tent Labs anti-jitter modules. On DI/O I used XO2 module &...

Thanks for all of your help, I got the INA mod working, and it's been breaking in for several days now. The sound is more detailed, and I think that it's...
Hello DAS, I will be using the AD's to build a differential output stage (like the INA103 basically). This is what sounds best to my ears. The AES/EBU...
... No, you want the output RCA's isolated from chassis ground. Just wire them up to the ground connection on your INA103 board. ... This doesn't sound right....
Anyone know what should the current (mA) raiting of the 5V regulator in the DIO be? I have a hunch that the 300mA Audiocom Super Regulator I'm considering is...
Hello, Who tried AT&T ST-optical glass interface on both D/IO and CD transport?. Where I may find circuit diagrams for ST implement? regards, Krzysztof...

Very sadly, my DIO is dead. I think somehow I fried the digital board when I tried to hook it up to a new CD/SACD transport. Now I can only hear weak distorted...
