Hi,
after reading through the BIIIse-Pro thread I got some questions about the new tridents-sr.
1: Would the tridents-sr/avcc-sr be also of benefit for the BIIIse (ES9018) with latest trident/avcc (shunt version). Or is this only true for ES9028/9038?
2: Should the voltage also be set up to 3.3/3.3/1.3 trident and 3.6 avcc?
Regards
Branko

1 - Absolutely! In fact I tested first with the ES9018.
2 - Yes - that scheme works well with that DAC as well.

I've got a BUFFALO III (non SE) that I finally had the time to put together. Left channel has distortion, especially noticable in a certain high-ish range. Otherwise fine. Any ideas what it could be?
It's hard to say - what output stage?
The first thought is that it is possibly a dead/damaged AVCC module? If you have a very old AVCC module I would highly recommend updating to the AVCC_SR.
Cheers!

I'm using the original IVY. It is OK because if I put a BII back on there, it's distortion-free.
I tried replacing the AVCC from another BIII and it doesn't seem to help. Tried another source (both original OPUS). Anything else I can try swapping out?

That's kind of a bummer. I haven't done any flashing of any kind so It should be. Are you referring to the ESS chip itself or the bios chip that can be popped out?.
FYI, if anyone is interested in taking over my BIII SE/Cronus/Hermes/BBB streaming project.....

Hello,
just tried the new Tridents which were bundled with my Buf 9038 SE pro on my older BIIIse.
I first lowered the Voltage of the Placid HD to 5V.
But with the new Tridents there was no sound (measured Voltages on Tridents, 3.3 and 1.3, and AVCC, 3.6, which all were OK). On the Placid I have 150 mA Shunt. When I swap the 1,3 V Trident Sr with the older Trident 1.2 V I have lock and music is playing. Do I need more current?

Hmm nothing has Been mentioned about the Lme 49600 at the Mercury why? I really ca'nt use this.
See the...
Mercury thread, the design is explained quite well there.
If you have a bias against IC based designs, I would suggest suspending that and actually listening to the Mercury.
If you absolutely must have a discrete output stage due to ingrained personal beliefs, I would suggest, perhaps, designing one and sharing it with the community.

To Add to what Barrows wrote above - I was also sceptical of the LME49600 based design, having not really gelled with the part in another application.
However, in this application, Mercury i/v, it works brilliantly. B3SEPro (9038) and Mercury come to gether to make a design among the best da converters I've heard (and I've heard way too many for one lifetime). Don't let any preconceptions delay you trying this combo at least - if you still don't like it then, as Barrows suggests, we'd all love to hear something that does a better job.

I put the new 9028s on top of my old (tweaked, discrete) Legatos and the improvement was surprising. Versus 9018s, the additional DAC current is very noticeable as higher output voltages/volumes yet the quality of on-chip volume control is good enough to maintain the resolution advantages in the lower end of the volume range. The LME49600 on the one Legato used for headphones, however, bit the dust. Overdriven? No problem, I had stopped using it anyway...

Should have added...
IMO, the BIII Pro boards (running PCM, in my case) represent such a significant step forward in signal 'purity' that my own biases about what is important downstream from the DACs have been seriously challenged. ...and that goes all the way to the drivers that are pumping air... There's much less 'junk' that the downstream system needs to somehow manage/filter/neutralize.

The 9028 outputs the same amount of current that the 9018 output, so overdriving the Legato in not really possible.
I am sorry Brian and Russ. I am so dissapointed because off the Lme 49600. In.my oppinion IT destroys everything Called High end. I try to repair with colouring with cables and Kasei.
I’m no engineer (obviously! 😛) but output levels definitely increased when I swapped in the new B3s - with no other changes. This extra amplitude is actually welcome. I don’t particularly care what happened to the LME49600s - the balanced -> SE circuits are no longer powered nor needed.
