I had a good chance to listen to the Hegel H30's last night and I still plan on doing the stereo vs mono test later this week.  After about 6 hours, they were sounding damn good.  I switched from the Classe CP800 preamp to the VAC Preamp and it was a different presentation:  more roundness to the instruments, increased texture, vocals were more forward, etc.  It was good evidence that tubes in the chain somewhere (if not everywhere!   

 ) can produce some positive results.
