As upgrade rush bites again, planning to perform some tube rolling on my Rouge Ares Magnum. Please share some experience with tube rolling on pure tube circuit topology phono preamps. Practical experiences are preferred. Theoretical options are welcome too.
@pindar. I've paired a Kenrad VT231 Black Glass with a Sylvania VT-231 in my amp. Two very different tubes providing dynamic holographic sound. And a Tung Sol BGRP in my preamp.
My 845 Mono's Input design is a little unusual as it has certain Tubes in Pairs that are only using Half of the Tube in the Circuit. There is only One 6SN7 Per Monoblock and these are only using Half of the Tube in the Circuit. It is always difficult to explain a Bespoke Built Design for the SQ, there is a separation in SQ and usually the only way to fully comprehend the designs capabilities is to be in the room with it.
It is very often the case that when dual triodes, like nearly all the tubes so far mentioned in this thread, are used in circuit, only one of the two separate triode sections is actually used. But what is a BGRP? Thanks.
BGRP - Black Glass Round Plate. I have a pair of 12AU7s Tung Sol black glass (grey standard plates, I think) that sound fantastic, with great extension, but they are lowly 12AU7s: )
