Wait? No need to wait. The "3" is available at the store here... the diyaudio store. Now.
Reports are that the "3" is better... but you should read the thread and see what you think.

Ahh, now thats loaded question, Im just about to finish the pearl 3 and audition. I(Once Ive built the PSU) Ive just washed the PCBs and are still drying. The Peal 2 has bettered all that Ive tried against it in the past 5 years. Im hoping the Pear 3 will beat it but want know for a few days yet. The Pearl 3 is a no brainer as it comes with 'almost' everything you need to build it.
They powered up first time on the bench with no issues. Ive just got to check the R27 bias and I'll be good to go.

Thank you so much, I am eager to see what you think. @mhenschel lol you are correct, I just found it. New to this site so...
So Ive thrown this thing together just to see:-
A) Will it all fit in one shoe box case, yes no problem.
B) Will it hum if I do A, the answer is yes, very very slight hum. I have to put my ear unto the speakers to detect it. Work in progress.. shielding round the Tx.
C) Does it sound better than the Pearl 2, early hours / days but yes it does. 🙂

@arupgowda I’d suggest the Pearl 3 over the Pearl 2 just because the PCB set is a better value and come with a lot more components, and is easier to use with MC cartridges. I also think it sounds a little better.

Free to a good home: a 3 year old Pearl 2 with a wonky left channel. Worked great for a couple of years, and I loved the thing. Dead quiet, sounded amazing. Out of nowhere it started popping on high frequency peaks. I inspected my solder work, redid some. Replaced the ZVP3310A Mosfet in case I'd marginalized it during the original build. No joy. I'm kinda done trying to figure it out, and look! A Pearl 3 kit! I'm going to build one of those.
I could probably kit bash from this, etc, etc. but...maybe someone smarter than me can sort it out. See the pictures, it's not an embarrassing build. I don't think. But it's going to sit on a shelf doing nothing forever, so as a small way of giving back to this community, if you're not just looking to strip it for parts and you want to have a go at this thing, DM me. It's yours for the price of shipping. I'm in Southern California.
Best,

My two cents on Pearl 2 vs Pearl 3. Pearl 2 is really about low output MC cartridges. Mine did fine with a HO-MC, 2.5 mV. Many had to lower gain for MM with mixed results.
The Pearl 3 handles this with NO issue. I tried it with all the cartridges I had at time, Ortofon Super OM 30, Shure V15 xmr, and SAE 1000 LT.
I ran Pearl 3 with the OM 30 and thought it better that Pearl 2, but a gain mismatch really. I bought new moving coil, AT 33ptg/2, and thought Pearl 3 was very nice. First thing that gives Salas phono pre any competition at all. Which is better, Salad or Pearl 3? That's a closer fight...to be fair, should try new MC with Pearl 2.

Well, both a Salad and the Pearl 3 should be good for you, particularly if enjoyed together.
Actually, I am interested in the Salas and Pearl 3 comparison regarding sound flavor. I have the Salas and a Pearl 2, and find the Salas less colored sounding, yet so beautiful to listen to. I bought a Pearl 3 kit but haven't built it yet because it would seem to be maybe a little hotter than the Pearl 2 given the descriptions I've read. However, I am encouraged to read you like it better than the Pearl 2. If you have a chance to compare the Salas and the Pearl 3, could you PM me with any differences you perceive in overall sound flavor?
Thanks
auto correct keeps changing 'Salas" to salad...I wasnt using Pearl 2 in its design area, Lo output MC. But the Pearl 3 I find superior. The test between Pearl3 and Salas is closer. Im happy with both!
Greetings everyone...I'm a first-time poster so please go easy on me 
I have the Pearl 2 boards (yes, realize there's now a Pearl 3 available), but I'm at loss in building the PSU. What I've found in this thread seems to be different versions of a PSU and maybe what I'm looking for is a specific PSU build to reference? Is there a blueprint or BOM list as reference for a simple PSU?
I've resurrected non-working tube and SS amps (HH Scott, Marantz, Sansui), recently did the Elekit 300B, but never built anything from scratch. Perhaps I'm in over my head by doing this project.
Appreciate any help! Thank you 🙂

The PSU which provides the raw power is fairly straightforward, since the Pearl PCB's themselves incorporate the voltage regulation per channel.
You just need to follow the schematic in the Pearl 2 documentation, it includes the IEC inlet and fuse, bridge rectifiers (converting AC to DC), capacitors and the connection to ground (using a rectifier bridge to prevent ground loops).
There isn't a BOM per-se, most standard parts are fairly adequate for the job as long as they are rated correctly.
You can build this point-to-point, or alternatively, I designed a PCB that makes construction easier. I think I have some more left so you can PM me if you need one. Attaching pictures from my past builds. In either case they fit nicely in a Hammond 1455 case or narrow Galaxy 2U.

The simplest would be something like this (slightly modified from the Pearl 2 article to fix a missing connection):
