The Ref 1 is outstanding in a number of respects. The Ref 1 is unique in being able to simultaneously combine accuracy with musicality. It reveals layers and layers of new information from old recordings that I have heard many times, but it does not sound harsh or bright. The Ref 1 also has a truly astounding dynamic range, and the transient attack of instruments is quite amazing. A plucked instrument leaps off into thin air, seemingly appearing 5 feet or more in front of the speakers.
Massed strings sound luxurious and woodwinds simply sound gorgeous.
No one part stands out, but it sounds coherent, articulate, and alive. I cannot imagine higher praise for any audio component than this. The Ref 1 remote works no matter where I'm located in the room, even at a very acute angle. The brick Levinson remote only works almost dead-on flat. I'd take a cheesy remote that works over a fancy aluminium remote that does'nt anyday.
