    My experience with my Cornwall II was that they were much more civilized when driven by tubes. Will you be driving them with tubes or solid state?

    I haven't personally heard the exact component load in your C51s, but I've been impressed enough with the 030 load (D130 / 075) to imagine you'll likely like your C51 better than your L100s at least....

    Thank you!

    I guess I never took a moment to appreciate that the N800-D is simply a 2nd order Butterworth with HF attenuation. That being the case I suppose I could use the pots I got after all,...
