We enjoy our Modwright Oppo 105 after visiting RMAF or other shows I have no feelings it is second to any other gear. It replaced a much loved Modwright Sony SCD-XA777ES. The Oppo sound and video are amazing.
I've tried a small number of vacuum tubes ended up using new Shuguang Treasure CV181-Z tubes saving the vintage ones for my preamp. I'm not saying there may not be a better 6SN7 out there for it. Oh yea Dan says a Mullard rectifier is a good choice that's what I run. Never did try any others.
