" I always roll phono stages / arms / etc when trying to optimally match a new cartridge.. "
Certainly I understand try to match the tonearm/cartridge combinations and even a SUT ( I did it in the past till I found out the top Denon SUT that I changed only when the cartridge need it higher gain. ) but to change electronics ( as in this case the phono stage ) just to match the cartridge let me to ask: why? .
@rauliruegas Why not? It boils down to the very topic of this thread: synergy. Every phono stage I’ve used has its own distinct sonic signature & nuances. I still keep many on hand. They’re useful for a different perspective, an occasional change of pace, or a better match to certain cartridges. It’s not just "match warm with bright" either - it’s sometimes more complex and unpredictable than that (though not always). Multiply this by the complexity of matching SUTs or MC pre-preamps - and you have the countless possibilities worthy of an enjoyable hobby :)
Of course I still have favorites. Audio Research Reference 3SE’s Low Gain mode (paired with SUT) was stunning. VAC Renaissance SE (also with outboard SUT) has been my longtime reference. Herron VTPH-2A (also with SUT - see the pattern?) pairs super well to my Koetsu Blue Lace, but had me running out the room with Windfeld Ti. And Hagerman Trumpet Reference has a warm open sound, vaguely tape-like, that I quite enjoy. Now I also have the new Hagerman Piccolo Zero to experiment with current injection!
Folks on this forum will discuss cable rolling without batting an eye. I can assure anyone the changes from swapping phono stage are orders of magnitude more significant.
