Thank RainTalk.

The "F2" version (for guitar bass,sub etc as i said before).

as you see, AP declare the rms power output Vs the lowest load in accordance with good performances. This means that the amps are much more generous in power. "F2" is declared 600w (4R) at 0.04% of thd, right for example. F2 height=30mm (ref to pcb)
well...need F3 a this point

Hi,
first of all it is my duty to say that these results are the product of a collaboration with other engineers in MDI Team.
For toroids output, after testing with 16Amp output, under many aspects of behavior (all toroids available in the market), including the wire to be used and the way of winding. I got what I needed, with original AMIDON, solid wire (2x), so I excluded FERRITES couple or as other multi wired.

This product includes all of our experience, especially on the definition of high band already obtained perfectly with the SDA-400 as AB Class. but it would not be possible to get this incredible new performance in the dynamics without another long study called "DPS-500/600"

I agree, although I know that there is some problem with the management of the new software.
however, I think that the shop has been updated with the new F3.
