Don't agree with Rfogel18 at all. The CAT is in another league to most all preamps out there. To bring it up several notches, tube rolling is what I found to really make it sing. IMHO, the Modwright isn't in the same league at all vs. the CAT. Add some NOS Mullards to the CAT and again IMHO, neither is the MP-1.
As they say, the CAT rules.
