Reviews about the predecessor P130 preamp.

"...KR Audio might be best known for the proprietary tubes the size of one-liter pop bottles that they use to get real world power out of single-ended triode amps, but their lineup is more diverse that that. Their P-130 pre-amplifier might be the sleeper in their lineup. A densely compact chuck of equipment carved from solid aluminum case with two big tubes on top, single-ended (balanced ins and outs optional), with a built in moving coil phono-stage in the number 1 input. Everything about this pre feels high quality. Best of all, it sounds high-quality too, with excellent bass extension, a large, deep soundstage, excellent clarity, and that elusive musical boogie factor. A terrific piece that’s been a joy to listen to with anything I’ve played through it..." CLICK HERE to read the entire review
