I have no experience with BC integrated amps so I'm not sure that this will be any use to you. I own the BC206 and just recently the BC208 and they are special amps indeed. The 200 series has an effortless quality about them that never make you think that the music is being forced at you. To my ears, these amps strike a wonderful balance between speed, transparency, detail, and dynamics without over emphasizing these qualities so that it becomes too hi-fi. There is absolutely nothing mechanical about their sound and it is this effortless finesse that makes the BC gear sound so human. If the Katlas gets you closer to the 200 series, I would definitely try to seek it out.
You should check out the Blue Circle forum if you have not already done so. There is usually someone there who will be able to offer their experience. Gilbert is also very accommodating whether you are buying new or used - he's very passionate about what he builds.
