I had the P30 in my system for a couple of days, together with my newly purchased Hegel H30. I thought it was very nice sounding.
But compared to the Classe' CP 800, it just didn't measure up. The CP 800 allowed the H30 to really sing. With the Classe', the soundstage was bigger, more 3D, greater clarity, better imaging.
The music had a much more open sound, much greater air. I couldn't find one thing the P30 did better than the CP 800. The P30's volume control was not very good to use with the remote, the volume jumped in bigger increments than than I like, and very,very fast.
I know I may sound a little harsh, but I'm not bashing the P30, I'm comparing it.
For people that have had one in their system, you already know what I'm talking about.
For everybody else, let me tell you something. I've paired the Classe' preamp with Constellation,Solution, D'Agostino,EAR,VAC,Classe', and a few more.
If you really want to know the truth about how your amp sounds , pair it with the Classe', then you will understand what I mean.
Of the preamps I've tried, the CP 800 has the least affect on an amps sonic signature.
