It seems every one is recommending you some kind of tube amp when you are looking for a solid state one. Unfortunately as fine as the CAT is, it's achilles heel is the slight grainyness in the treble & slightly forward midrange. These characteristics will exasperated when matched with most ss amplifiers today, especially with the likes of Classé, Krell, etc. The only ss amps that are truly musical are Lamm Industries ML 1.1 & 2.1. These amplifiers do not exhibit any of solid state nasties, in fact you will be so impressed by their tonal accuracy & full bodied sound that you will never miss tube designs.
