A good tube amp can be dynamic, detailed, and musical. My opinion, buy a tube integrated, such as a Jadis Orchestra Reference(NOT Orchestra) for $3500. This amp is VERY dynamic, musical, and has a wonderful passive linestage(that you will find very detailed). Get a Musical Fidelity A3 CD player for $1000. Buy whatever speakers you like for $4500 or less(one's that are not REAL hard to drive). You can go with an incredible variety here, as this amp has a LOT of guts(due to the HUGE transformers w/KT90 tubes). Spend the other $1000 on good speaker cables, and 2 power cords. No interconnects! This is a system you will live with for a LONG, LONG time.
