I would defintely agree with that, now crappy recordings which didnt bother be before as much are almost painful to listen to... I was listening to a classical CD of mixed composers and I could hear them flipping pages in the background, and a guy sweeping or humming or something...
but the good recordings are almost blissful... I have some Dave Matthews live that was well recorded and you can here the plucking of the guitar and its amazing...

Hope i can afford to buy one someday
You describe the sound with same words
i use when i heard tripath for the first time.
Anybody use Buffalo32S with tripath amp?

Yes, using Amp4 (Tripath amp from 41hz) after a B32S. It's important to feed a Tripath/dig. amp with batteries! I feed it with 24V batterie. Excellent sound! It's the best amp i had till now. Cheap also.

The bass of the 32s is indeed excellent. Contributing to this is the dc-coupling in the IVY-circuitry. No rolloff and - even more important - strictly linear phase in the lower bass region. If possible, try to use dc-coupling within your entire chain.

I'm working on it.....only one capacitor left at the input of my Elektor poweramp.

They look bigger than the LCBPS. What are the dimensions? And will you offer a LCDPS equivalent as well?
[EDIT] Two sets of trimpots? Beyond my skill to work out what is going on there 😕
Oh, and off topic...... I was on Facebook this morning, and both Brian Donegan and Russ White came up as friends suggestions. How in the hell could Facebook make that connection?!?

Yes they are a bit bigger than LCBPS. I needed to have space for the big heatsinks and I also wanted to lay it out in a way that makes it possible to mount directly to a metal case allowing the case itself to be the heatsink.
3" x 3.5"

The two pots will be pretty easy to understand with the manual. 🙂
One sets the current through the CCS (this will effect maximum output current).
One sets the output voltage.
The practical range for this PS is ~ +/-3.3V to 20V or so. I am not sure on the top end yet.
Cheers!

If the two GNDs were not common, and a 4 instead of a 3-output connector were used, the board would be more universal. By not joining the two GNDs at the board level, you may also gain more freedom to avoid ground loops. And you would only need a single board in your inventory. Preferably, this could of course also be an LCDPS. By appropriate connection of the output voltages, you could use the board to supply either bipolar or dual supply needs.
Is there a possibility to further expand the output connector with Kelvin sense pins? Maybe in a next revision?

Javin5 said:
Hi Kurt, I took a different approach here. This is a truly complimentary circuit. Not just two regulators in series as I had said was (and is) possible.
There will be a smaller single supply that can be used where you would use LCDPS. I just decided to do the bipolar version first.
Kelvin sense is possible, but I have found it not especially effective especially if the wiring is short.
Cheers!

Russ White said:
Russ, I fully agree as long as the wiring is indeed short. Also, it is my understanding that to do the Kelvin sensing right, you will actually need two sense wires. My thoughts were that the sensing might allow you to put everything related to power supply stuff on one side of the chassis and all the analog stuff on the other side, which could result in somewhat long wiring.
Anyway, I'm looking forward to your new supply board, and thanks for all the work you are constantly doing for the DIY-community.

An externally hosted image should be here but it was not working when we last tested it.
I'll write my impressions after I've listened some more.
Russ,
are you going to publish the diagram, especially output stage? or at least reveal it to those diyers who purchased B32?

This DAC sounds awesome on first listen. Most impressive is the detail in the rear of the soundstage. So much detail behind a singer such as Norah. Much more detail on first listen than even the dual mono Opus.
Great job, Russ.

Great job, Russ.

As I have said from the beginning I will mot publish the schematic yet. 🙂
I do not want it to be copied right away. 😀

Thanks Craig,
I really appreciate that.
Brian deserves a lot of credit as TPA would not exist without him. I know I am very grateful for for his dedication.
Cheers!
