I have this thing for combining tube preamplifiers and solid state Class A amplifiers. Some might think that there is just too much chocolate in the pudding, but I love the coherent, fleshed out musical connection that this combo can provide—maybe the best of both worlds.

Like the biblical hero depicted in Florence, Italy's famous David statue by Michelangelo, the diminutive PA-10 is angular and elegant, but capable of bringing down a giant or two by slinging notes with speed, precision, and wallop.
