Thanks for your reply! My preamp as an acttive design (have been using various passive as well - ELMA attenuators 24 step) The volume nob is a multiturn so there is no 12.00 setting. But ther is a damping scale in the display and I normaly have a damping of about 40db and down to 24db at some classical recordings whan I am home alone.
My initial request was also if I would get any benefit of beefing up the toroide and I was not sure my self this was the way to go. But as VA is not the only important factor I still look for information of what would make the best toroide? I can have one custom made and can choose my self how it should be made. Many owners of the ZapPulse have experienced improvement in sonic quality by using bigger toroides but to my knowledge bigger is not always better. Hence the question about best quality! If bigger is not the way to go then what?
By the way thanks for your patience ;o)
Have Fun
