Hi c-J

My original intend was to get a new power iron! I know I would not get full power with what I got!

I also do not need the power to be kicked out of my flat ;o)

But I want it for dynamic headroom! If you listen to uncompressed music like classical music there are much more dynamic information in the music that is realy putting strees on the amp. Therefore I want a solution with the current modules that leaves no limmit at all. No matter the cost.

I don't know the actual design but only 18-20W is disapated in a modules at full power (290W) and it can be decreased further by adding a seperate gate driver supply) You might find more information here: http://www.lcaudio.com/index.php?page=70

So back to my original question! What would be the optimal parameters/materials etc. for a state of the art torodial X-former?

Would I have any sonic benefit by oversizing the X-former to as much as 3kVA? Ore would there be other more important parameters (guage of wire, core material, shielding etc)

I know that the rest need to follow! I already have 2 rectifier bridges capable of 35A 400V and the current capacitors are not bad at all. But I might need new ones if I should go for higher voltage (if this would add any positive sonic results). And maybe even more capacity is needed? Currently I have 4x10.000uf. With a class-D amp that almost only draw power when music is pressent this should not be bad at all.

Have fun.

You want to post the specs of the amp.. - cheap-Jack 13:00:38 02/27/06 (9)

Here thay are! - Granholm 13:13:26 02/27/06 (8)

Are this the spec you need? - Granholm 10:16:22 02/28/06 (6)

Yes, I got it now. - cheap-Jack 11:15:56 02/28/06 (5)

Good! And some more details! - Granholm 12:26:10 02/28/06 (4)
