I've just introduced the TAD-60 tube amp to go with a Placette passive pre (total <$2500). The instrumental articulation, detail, tonal accuracy, depth, staging and musicality have all appreciably improved. I think it matches the gallo quite well - it smooths some of the brightness of the tweeter, and it really shows off the mid-range beauty of the speaker. I also don't feel compelled to rush out and get a sub-woofer amp. I've only been listening to the TAD for 3 days so I haven't yet gotten beyond my initial impressions and enthusiasm. It'll take more time before I reach a more considered view. Just wanted to share my experiences with matching Gallos.
