My friend M's system has evolved over time and he's just recently taken yet another big jump. His priorities are accurate timbre, timbre, tone and more timbre esp strings...think yo yo ma's cello. He needs some valve always (hence the pre) and definately considers his Tuner & LP as stable (before digital).
