Someone has been busy...

I would think it would be rather easy to show in RMAA?

See The β22 Stereo Amplifier, Parts List: "Please note that in the 3-channel "active ground" configuration, some part values in the ground channel differ from that of the left and right channels. See the following table:"

Happy Birthday!

oh fuck... you broke it

BTW, where do you (you being any of you woodworking dudes) recommend buying wood finishing products? I don't even seem to find varnish at places such as Home Depot, etc. (unless I am looking at the wrong thing). Polyurethane, sure; varnish, no.

As in Tellig?

That would make more sense if there was a panel behind the front panel that it was mounted to via a mounting nut. That is how my preamp is done for the switches, pot, etc. That jack that MisterX pointed out looks like it could be a contender other than the lack of gold plating.

You would have thought they would have made the PCB larger and mounted it securely and use that to support the jack. Gluing it in as Nate said is pretty lame and bound to fail sooner or later.

Happy Birthday!

I actually see some value in AC/DC. Metallica on the other hand...

I don't doubt that they all get all the data there. SPDIF is not just data however; there is an RF frequency clock riding on that data which is really more of an analog signal as it is not the levels that are of interest but the edges (timing). At 2.8MHz, reflections, etc. become an issue. Really poor interface design, and the whole reason for reclocking schemes, ASRCs, etc., which do jitter reduction and make the DAC less dependent upon the transport timing. And I should have said "One probable reason why I've heard digital cables sound different." since I don't use an external DAC and haven't personally gone thru myriads of digital cables as some I've read seem to do.

Yeah, between that thread and the Valab DAC mod thread (Valab NOS DAC - subjective listening and modifications - Head-Fi: Covering Headphones, Earphones and Portable Audio), plenty of crud on the inside of the monitor (great analogy by the way... my monitor is glad I wasn't drinking coffee when I read it ). I keep getting the visual of jumping the shark in that one, but decided better to just stay out of these types of threads and treat them as a car crash in progress.

That's only 53C, so not that hot. I know TDA1541As habitually run hot.. many develop distortions, lots of time only in one channel, so you will see people putting DIP heatsinks, etc. on them. Never measured temp on them nor read temps anywhere though.

AES/EBU is supposed to be 110 ohm (like SPDIF is supposed to be 75 ohms). An XLR connector is not. The majority of implementations of either are also not properly terminated at the char. impedance. And probably don't use coax or controlled impedance cabling/PCB traces either. It still works, but not optimally. One probable reason why digital cables sound different.

I assume the panel is metal? Aluminum? Steel? You could probably get most if not all of it with something like an xacto knife or the like. Possibly have to carefully drill it out. Or use a ream, again carefully. That jack doesn't look familiar. Was it completely broken apart like that when you opened the amp? That would explain the no resistance. But yeah, the entire jack needs to be replaced.

Oh gawd... Audio Asylum

Like they said. Sorry to hear that Duggeh.

I looked at that. It wasn't that stellar. Nice backpedal BTW!

I don't know what kind of jack this uses, but yes, you should definitely feel resistance as you insert the plug into the jack. On normal Neutrik switched jacks, when the plug is inserted, it lifts contacts off of the switched set of contacts used for preamp or whatever, thereby taking them out of the circuit. The fact that the pre outs still work would indicate that the plug is not disconnecting these. I would think it should be an easy fix.

Seems like they put Terminator in the Friday slot preceding Dollhouse when it was intro'd. Didn't do anything for Terminator (other than ensuring it got cancelled), and almost took out Dollhouse as well. I know Terminator was expensive, but it does suck that it got cancelled, particularly with the other really mediocre shit that is on.

I'm guessing most of the diff you are hearing between the D1 and this is due to the output stage. I wouldn't personally bother with opamps (other than maybe an OPA861 transconductance stage), but would go for a discrete stage. Zapfilter would be the easiest, though probably not the best. If you do decide to go the Burson route, I would probably do one of the Audio Gd ones, as I suspect that they actually make the Bursons, and theirs are more reasonably priced. Note that for I/V duty, a discrete opamp << a discrete zero feedback I/V stage.

Thanks for the wishes all! I had a nice day.

I was still under the impression that few do spdif termination correctly, even now. I would agree that Empirical products aren't what I would call a good value

Yep. Hang in there and things will get better every day. My thoughts are with you and your family as well.
