Hi vitalica.
They will be ready by next week.
We have changed the size of the heatsink and added a low noise smps before the +5.5V low noise regulator.
But everything still fits in the space
The wrongly made LPS (V1.0) does work but is limited to 200mA on the +/-15V and 100mA on the +5.5V (can be adjusted from +5V to +6V)
I sell the LPS V1.0 to 75€/pcs until the 9pcs are gone.
Hi Sonnya,
No news about the new version LPS?
Unfortunately, I can not finish the project

I work a lot on PCB designs at the moment. Just ask bavmike.
Tomorrow when i have spoken with the PCB manufacture i can tell more.
It uses larger heatsinks now. PCB has ventilation holes around the heatsinks.
The +5.5V which generated a low of heat is made up of an LM2674M simple switcher with fixed frequency so the noise from it is very low. On top of that it is followed by a low noise voltage regulator from TI. TPS7A4700. So the +5.5V is very low noise as well and heat is lower.

Hi Sonnya,
Is this version of the frontpanel capable to send sw commands to any AK4490 dac?
At least volume control and filter settings change ...

New firmware for the frontpanel when used with the DAC only.
Two weeks ago we have made a new firmware for the frontpanel used with the DAC only.
I'm selling my dac/pre amp. Anyone interested please send me a PM.

I have similar question about 1 months ago and so far no response from Sonny.
Quite frustrating actually. It seems to use this DAC to its full potential, we will need to buy the full package of pre-amp, front panel, chassis etc.
