Default Volt+ D v1.3

BOOM.

Ladies and gents , Volt+ D (ouble) was received.

All capacitors in the analog path are film ()

We hooked up the Volt direct to speakers......testing team apparently started to dance (while normal in Bollywood movies I assure you it never happens in reality)

OK..OK I know its not a objective test.

I am happy to announce that Volt+ D revision 1.3 PCB is singing .

Next week... AP testing .

Damn, that looks beautiful. Any idea when it will become available in the US?

So finally an amp to open your inner Bollywood dance moves! Can I sign up for four Ginger Rogers mono blocks with stepped attenuators?

I suspect the most improvements in THD are related to these bigger and low distorting inductors as we've shown in the past.

Any plans to swap TPA3118 for the newer TPA3128 as this improves output impedance and burst ratio?

Hi All,

I have acquired TI's PurePath and would like to try my hand at playing with the DSP in the Piano 2.1. Am I correct in understanding that I will need Allo's .pfw files? Do they make those available, and if so, can anyone provide them?

I have some discussion on using TI's GDE with Piano2.1 at Raspberry Pi with Piano2.1 DAC DSP and Volumio2

Sample files in the thread at Raspberry Pi with Piano2.1 DAC DSP and Volumio2

3156 is power pad up and bonded in reverse. Those won't fit on 3128/3128 boards.
