Mapletree 2A os first rate. Tube regulated power supply in a separate chassis, point-to-point, and 6sn7 or 12sn7 (cheaper NOS)with the flip of a switch. Previously owned CAT, Lamm, ARC, Dodd, and Joule - all wonderful, but this little preamp, $800 with blackgate filter capacitor upgrade should not be dismissed because it is not $5-8K; it will suprise the heck out of you...
But for me the best preamp, at any price is the $450 Lightspeed Attenuator - limited to 1 input/output, and you need to basically use tube amps fpr high input impedance, but it is the best I have heard for my taste.
