Pass Labs works very good with B&Ws. I was driving my N803s with the X250.5 and loved it. You do need good amplifier with B&Ws and also a good speaker cable.
B & W Naut. 804S-Appropriate power source???
I have a 7 year old pair of 804's and looking to replace my Arcam Alpha 10. Speaker placement aside, the sound was not as immediate or detailed as I seek. I have read where The Nautalis series is better served with tubes. With a budget around $4-5K any reccomendation SS or Tubes??
