Nice statistical analysis and I am sure Jason the admin knows all that stuff very well.

They allready are the first ones to copy anything they find around. Strangely I do not find many posts from china here

Rare and expensive components for a potential very small market.

Hi Salas,
Thanks I'll see what's there ,it might be tomorrow night before I can get to it,Girls first toys second,lol.

Hi Salas,

Got it working,I have NEVER had a open resistor right out of the bag, R6,oh well I learned a new trick,When everything else is ok check the source to ground,lol.I usually check the R & C's before I install them,my bad,
The boards sound good,out of 2 shunt PS's and 2 Phono boards ,I caused one mistake but they went together and worked first time,GREAT!!!I was surprised for sure,My cartridge is over 30 years old,still sounds good but a new one is in order,I have found some denons,black,green and blues Have you a favorite? I am looking in mid range area,I have read that the black is the same as a green just didn't make the higher spec,
Thanks alot!

denons,black,green and blues .. what do you mean ?

Salas how much current draws the 63dBs to calculate the dummy load for PSU?
