I owned a Jolida 502p amp for years and it worked beautifully, but when a Dennis Had Inspire "Firebottle" SEP (pentode) showed up as a barely used item on Ebay I jumped on it. I realized (even before switching to very efficient speakers) there really is something to the smaller single ended tube amp, and these Had amps, although somewhat rare due to Had's relatively tiny product output, are outstanding designs utterly handmade.
