having had pre's with both internal and now,external power supplies...a first sound delux with paramount upgrade...i can say that this is so much better then the many others that went before it....i think the design concept is pretty sound...no pun intended!!!
Preamp design approach - Power Supply location
Looking to hear from some design types or those who know something on this area. I have had both type of preamps and cannot myself say which is better but am very curious as to the perceived advantages of using external vs. internal power supplies (or vice versa).
