Hello Classical1,
Just you wait, it gets a heck of a lot better. 300 hrs or so and it really opens up and shows its magic! Are you using a BAT tube amp also? I'm one of the lucky ones who has 51se pre-amp and the 150se mono-amps. Over the years I have heard a lot of the competition and I have to say I will be a BAT customer for life. I must add they are great people also.
Enjoy,
Tom
