found this thread most interesting as i am both a bat and cary fan. the bat vk 5i pre is very nice, even with it's age. recently upgraded tubes for $350 was like getting a new piece of gear. i tried the vk 55 tube amp and was not "wowed" by it. i once had a pair of AES (cary) six packs and wish i had them still as they were as smooth and silky in sound as i heard tubes could be. my gal even noticed...she called it a "creamy dreamy" sound. but, the heat of the tubes was unbearable in the warm seasons so i went to the bat ss vk-220 with bat pac. a very nice combo for the spring/summer. very happy with this pairing. but, again, i miss the tube sound that goes really well with a fire and cold weather. so i am going to find myself a cary tube amp of some sort and have a perfect mate for the full time bat pre and its ss sibling. which cary? well, my cary sli-80 int that sits in a box unused goes for +/- $2k on a-gon so that's my cary amp budget. my speakers are sonus faber strads and the gear above works well enough for me although others might increase their budgets to higher levels. i did have a mac int 6600 and loved the blue glow but found the bat and cary better suited for my ears. hope this helps.
