Years ago, yes. Krell was the amp in my very first system. Due to not having a good tube preamp I sold it at a considerable loss... couldn't get rid of it fast enough.
had I a good tube preamp like I do now... it may well have sstayed far longer. Might be here still for all I know.
A friend of mine has had exactly the 200 in his home a couple times and absolutely loved it.... with his former BAT vk5i preamp. I also had a vk5i preamp.
the Thor is vastly superior to the BAT vk5i.
