Yes, I was. Much more so than I'd anticipated.
I don't know how significant a role the H-Cat played in what we heard, but I have no doubt it's an exceptional pre-. The presentation that evening left everyone slack-jawed, except for maybe Bob and Jason. They had an inkling of what to expect, but things were way better than I'd anticipated.
Point being, the incredible sound we all hear that night wouldn't have been possible if the H-Cat weren't up to the task.
I never thought I'd sell my Butler Monads, but I'm giving them up so I can buy the new Spectron Musician III Signature Edition. Along those same lines, I'd almost given up hope of hearing a preamp that wouldn't detract from what I'm used to hearing, but the H-Cat is at the top of my list for a home audition now. It was that good IMHO.
