Is the AVCC Dual also upgraded?

TIA!

No , It is a slightly different circuit, and actually has a far better defined load.

I actually have some ideas I may try later, but nothing in the near future.

Related question... you mentioned that "Owners of the previous Trident can upgrade the error amp if they have the ability, but that will not make the two versions equivalent. There are several other changes as well. If you wanted to upgrade the error amp on the Trident you have many choices. I would suggest OPA209 and OPA211 as they are both known to work quite well."

Two questions... first, just how far down the path towards the new version does an error amp change take an original Trident?

Second, how about the OPA827 as a replacement?

TIA!

1) They will still be quite different, but the Trident 1 will now have better bandwidth and be a bit more solid into extremely dynamic loads. It's very difficult to make such a comparison.

2) That unfortunately would not be a good replacement for the error amp. It really needs a split supply and the minimum supply voltage is too high.

Thanks for the responses.

Having replaced my Tridents with the new Trident 3 I can say that it was a worthwhile change. There is just more 'goodness', with another level of information seeming to come through the mix.

Replaced my 4 Tridents this morning: I use two on the B-II, and 1 for powering each (Crystek CCHD) oscillator on my async USB interface; the oscillator on the B-II is unpowered, and I am synchronous clocking from the master clocks on the USB interface.
After a few hours of playback today, there is definitely an improvement, more relaxed sound (not that it was at all noticeably nervous or strident before) and better resolution of very low level details: ambience and more complete harmonic resolution of complex instrumental timbres. Very much worth the upgrade.
Thanks Russ!

Any tips on how to easily remove the old tridents? Thanks

Which reminds me of and old suggestion which I have never proposed.

Russ, you could make the boards a fraction more DIY friendly by increasing the diameter of the leaded-holes just a bit. When you have a tight fit and a 2 layer board the removal procedure is tricky . Both suction wick and tool are struggling reaching the solder and the risk of damaging the via is imminent.

If you have access to hot air rework station it is pretty easy to remove the tridents.
