Driver73, if you are seeking sound that is not fatiguing, extended in frequency, with very good macro and micro dynamics, and very fast but not abnormal transient response, Capri may work for you. On the other hand, I would not characterize Capri as layed back, if by this you meant moderate dynamics, slightly glossed transients, and a frequency range that favors upper mid bass through lower treble. Or in other words, Capri is neither stereotypically SS sounding, nor does it sound stereotypically 'tuby'.
From a compatibility point of view, the Capri has rather low output impedance -- 40Ohms single ended and 80Ohms balanced -- and should work well with Pass amps. G.
