The biggest jawdropping tweak I`ve stumbeled upon happened way back when I was searching to replace my old Denon DCD-3560. Tryed out a Wadia and a VAC discrete tube dac but I could not just leave that mighty Denon behind.
Got me a service-manual and started wondering. "What if I tryed to take out a true balanced signal directly from the four opamps instead of the quasi-balanced they`ve ended up with after the complex analog filter?"
So I tryed it, and WOW what a difference! Later I`ve came to know that there is no need for any filters after multibit converters like the BB`s in the 3560. And off course, one DC-filter is enough for a system, no need to duplicate.
Later on I`ve upgraded trafo`s, clock (at least twice) internal wiring, shielding and damping in the old Denon. It outplayed both the Wadia and the VAC dac back then and is still today in my system. Have two extra 3560`s for parts and two new lazers still.
