@rvpiano,
When you get the new transport, get it hooked up, and set down for a listen, take some notes on how it sounds to your ears. Play some CDs with female solo vocals and solo piano. Pay close attention to the female voice and to the piano. How natural does the piano sound to you? Is the sound full, or thin? Does the high note keys sound natural or brittle?
Any Diana Krall CD will do. Or any other well recorded CD by a female artist with piano accompaniment.
After 50 hours of playing CDs through the Transport listen again and compare what your hear to your previous notes. Take notes again and listen again after about 100 hours after playing CDs on the transport. Compare what you hear to your original notes.
Post back your results at the later dates on this thread, of yours.
