C33 was designed and produced in the 80's. Not a bad pre-amp, if you're looking for vintage gear. I own a C-32 mint condition, so I know what I'm talking about (C-33 may be considered its evolution). But if you're trying to get the best from your C.J., look for a more recent pre, 'cause a C-33 is almost unable to recreate a deep and high soundstage. Go to a more recent Audio Research, Conrad Johnson or if you like Mac, but don't want to be disappointed, try a vintage tube (C22) or a contemporary C45/C46.
