Twisted Pear Audio - Buffalo32S (ES9018 DAC) - Page 51

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.

Hey folks,

New placid adjustable shunt regulating power supply boards have been ordered for testing. I should have them in a couple of weeks.

I will let you know how it goes.

Cheers!

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?!?

Russ White · 12th June 2009, 12:31 PM

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"

Facebook works in mysterious ways...

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!
