For me:
turntable (external tonearm*) - phono preamp
phono preamp - preamp
dac - preamp
preamp - amp
* have never changed internal tonearm cables myself, so can’t assess
Where to put best interconnects
Getting a new tube pre-amp into tube mono blocks with one CDP as front end. Will have one very good, new set of XLRs to use and one good but much older set, each at 1.5M. Where to place the better set?
