System that has not seen many changes over the past years. Only changes have been new tubes for the AR LS-15. Most recent tubes are NOS Audio Research ecc88 dated 1983, West Germany.
System sounds fantastic. Hence no need to upgrade. Plenty done over the years to get to this set up. Dedicated listening room on the 3rd floor keeps the family out and the sound in. Many years of enjoyment and looking forward to many more.
They have been outstanding. Although some of the 10's have had issues with the mid/tweet cabinet cracking, I've had none. Plenty of control from the Proceeds. Fantastic imaging, soundstage depth and very coherent from top to bottom.
