A few weeks back I changed the opamp, diodes, and all power caps except the two smallest (closest to the tube socket). The unit worked fine after these mods. ...
Unfortunately I will have to state the obvious. You probably have a lifted trace somewhere. Check all of your solder joins and the pins on the op-amp chip, and...
A "lifted trace" means it's been burned up and no longer conducts. It's open. When I was using a $10 Radio Shack iron, I had that. In addition, there were...
Thanks. You were right on the money. I had lifted a trace between C18 and R7. It's now repaired, and singing like an angel!! ... addition, ... iron worked ......
For this type of thing, i usually need to see the pinout diagrams (get the data sheets and place side by side) and draw out the circuits to keep track of what...
Here's another option: G. Bronn recommended replacing U1 with two Burr-Brown INA103. Best of all, he put general instructions including part numbers on the...
I'm using a NAD C 521BEE as a transport. About 70% of the time, I have to switch the ART DI/O off for a few seconds when I switch CD's, otherwise it doesn't...

Actually, most of us have found that the DIO is VERY sensitive to the digital cable used. It definitely affects the sound quality and could easily be a part of...
There are a couple of things you can probably do to increase your lock. If you go on the DIOMods Yahoo group and download the Mods_by_Craig.doc file in the...
... If you replace a freebie interconnect with a great one, yes, it can. ... The problems I had with the DI/O were bursts of static, refusing to play music...

Even my MSB link is sensitive to the cable used (especially with length, which you might expect). When I used my DVDA player (my HT stuff is in a rack in the...
I had been teasing around with an idea of balanced outputs on a DAC to use with my Pass DIY aleph 30. I really love the sound of this amp and wanted to...
Hello all! I get DIO 4 days ago for listening with my Marantz 63SE. After tube removing the sound became even more dynamic and clear. All was OK and I decided...
Hi I've got a problem with my Cambridge Audio 640C cd player which I use to serve as transport for my unmodded ART Dio. Amp is sugden a21a and speakers Monitor...
Just to say, problem with cd player solved: opened it up and turned out to be loose connection inside. So much for my complicated view of things! If you have...
Some people have added a power switch to the D I/O. I've read that if you turn it off, then on again each time you change CDs, the lock loss is reduced. Jim...
Most of the time just cycling through the settings restores the lock. Funny, but with my current transport (EA modded Sony 7700 DVD player) the lock light...

It seems that most of the Chinese DAC's are some type of NOS chip. They do sound nice on simple music, but once things start getting complicated or big and...
I have to agree with Bob. I tried the INA103 output and the transformer output and for me the dynamics of the INA103 just feel more like what I want to hear -...

Mine's been running about a year since extensive modifications without problems. Once in a while it will lose lock for a 1/2 second. I haven't had to turn it...
Hi Guys, I am still using my DI/O with the power supply mod. Tried to replace the DI/O with an Audio Note DAC, but the DI/O beat it hollow - I'm still at a ...
