The Mcintosh C22 reissue or original. Being tube it is not that low profile but what tube premp is.
I love the C-22 my pal just got one, but it will not fit in my rack. I am currently using a Tandberg 3008a which is very nice ! thanks!
Weiserb: You could pick up a used TDS Passive Audioplile for approx. $200 and install it in the tape loop of any tube preamp (granted that it has one). Use the TDS for low level listening. This is what I have done in the past.
