I today installed the LM4562 in place of the 5532DD. I also replaced the 4 unnamed caps with Nichicon KA-series. Sounds good already but I expect some change over next few weeks.       Ikazu, sorry didn't measure the voltages.

I am out of town for the rest of the week so I am not going to measure anything soon.

Yeah, I actually bought the lm4562 to match with the opa2134s. But I first try if it works with the 6.4 times cheaper 5532dd without frying. If ok after couple of weeks ill plug the 4562 in. To make sure overheating wont be a problem I did some minor cooling mods: I added cooling fins to the op...

When mine broke I did change the 2 identical op amps. The dac seemed to work for few minutes and then started to distort sound again.   And I didn't quite understand what the cause of this problem was in fuens (#4) reply which he got from the seller or manufacturer. One of the capacitors...

Hi, mine might have done the same. Few days ago it started to distort sound when cold but the problem went away. The next day the problem came back for good.   Trying to figure out if its something worth fixing. I cannot find any components which are obviously broken (no bulges, leaks...
