I will ask for 8 Ohm 1W to compare.

I thought your Volt+ is "immune" to power-supply-noise"? So in the end we are getting the performance expected from the EVM, okay. Question is, will the performance be at the same level when skipping the cap. multiplier?

Isn't it kind of a moot question since the Volt+ comes with a built-in cap multiplier?

Of course.

Actually , if you look closely , we beat the EVM . I think there fair question is...can any modded board come even close to our test figures ? |

If i look closely, i see that you measurements are done at 20dB gain while all datasheet plots are for 26dB. So it's not comparable.

EVM data is not published at 20dB gain. How can one be so sure results are better than the published data ? Pointless discussion without the data. It's fair to reckon that this commercially available board has the best published measurements, without any mod. Even when compared to other cheap boards modded by diyers I have seen on this forum. It is available for sale, for a fraction of the EVM price. That's good news for the byers. |

To see the performance impact.

It has been measured to have 800-8kHz frequency respons, it was the best then too. At the moment the respons deviation might seem unimportant, but it points to either componentvalues being off more than 50% or still wrong measurement setup. From this measurement setup it is the best, nobody else measured like this. Or boards produced contain components more than 50% off, buy buy buy???
