If you look at the LDR attenuators' proof of concept, it seems that build one is straightforward, and, since it is simple, they perform all the same. At the ...

Today the first listening test of our new prototype. What must I say? Despite the fact that condensers and tubes are not yet rolled in the sound is just FANT...

The audio section of the Reference MM Phono Preamplifier is shaping up. Here you can see the input section with the Neutrik sockets, the OCC wiring to the re...

The CNC is now fully operational, here milling the case for the MM Phono Amp power supply unit.

Now, all our electronic devices come with a personal test card. Square waves, frequency response and THD/SNR for both channels.

We continue to work on the Phono Preamp, at this stage the first five exemplars of the tube power supplies are almost ready. here the 'naked' version going u...

After a successful test of the prototype boards; it's time for drawing the final production boards.

Starting to program the micro controller and design the logic board. This will take a while.

Finally the board with Audio section, with all the electromechanical controls is ready (hope it works), next step the logic board and programming the micro-c...

I started to prototype the new Passive Amplifier, here a sneak preview of the transformers with the relays array that will control all the amp.
