Audio Mirror WAVE DAC k


@audiomirror  I am very interested in the WAVE DAC.  I know this is a new piece of  equipment and not many have been made.  If by chance someone has this DAC could you give us some info and thoughts about the DAC.  Vlad if you are out there  can you tell us about the build and what's inside.  The website gives some info but I would like to know more.

Hello Brandon,

Which power supply? The 6 double regulated linear, ultra low noise ones for the digital part or the tube section one?The tube section power supply has tube rectifier, MOSFET regulator , dual choke and 2000uf, which BTW is overkill if you know how much capacitance tube rectifier normally requires. Also the MOSFET regulator is also a capacitance multiplier, which brings total capacitance way up than 2000uf. Also it has something some other circuit which I don't want to discuss. It is strange  you ask this question. I wonder what this info tells you? This is not a power amp. It is a digital circuit and a small signal tube section. If you want call me and we can discuss the DAC. 2816307917

Hi Vlad, almost all those questions about DAC storage capacitance related to LTA’s description of their Aero DAC. The way LTA describes it, you’d think they’re talking about an amplification device, not a digital-to-analog converter. They really make a big deal out of it. Having said that I’ve never heard that unit.

Hi @hasmarto,

Yes I agree that the way LTA describes the total capacitance sounds like they describe it as amplification design. If there is such capacitance in their DAC it is most likely to smoothen the edge of ZOTL design they use. BTW as I mentioned I have a capacitance MOSFET multiplier which works like that: You have a capacitor on gate of MOSFET and you multiply this capacitate by amplification(beta) of the transistor. Let's say the "beta" of transistor is 200. I have 680uf x 200= 136000uf right there. And this is a linear power supply. If I remember well LTA picture shows only one transformer and they say they use DC to DC power supply and such DC to DC converters are around $5 a piece. This is switching power supply. That explains the 300000uf. They need that capacitance.

I met Vlad this year axpona very very nice guy. I listen to his troubadour 3 with Moab speakers and Aric amp and pre , it’s sounds amazing. Vlad make good stuff service is excellent.
