This is a follow on to my comment above dated 01-22-10. As Emily Litella might say, "Ohhhh, never mind".
I wish to humbly but firmly retract my criticism of the Synchrony Ones as being colored or bright. I have now traced my listening displeasure to two other sources. First, I was using an amplifier that had inadequate current drive which caused soft clipping on peaks, giving a general impression of strangeness. Second, the room treatment panels I was using didn't absorb well at frequencies above 5 kHz, and this created an "acoustic fog" which overwhelmed the Synchrony Ones' excellent high frequency imaging. With those two items corrected, the Synchrony Ones are great performers.
My apollogies to PSB and to Audiogon members for my error.
