After getting back from a business trip today I spotted a CL ad for 2 pairs of Angstrom today . I was fortunate enough to be the first caller. Went and picked them up and the taller floor speakers turned out to be Radix 400's and the larger bookshelf speakers are Radix 200's. Not a lot on the web about these but from what I saw it looked like they were fairly uncommon. Overall condition is good but there are a few issues here and there. Have only been listening to them for about 45 minutes with some Vivaldi. The Vifa tweeters are singing quite well and so far I am very impressed with them. Anyone out there have some specs on these? The owner said that he bought them in 1988 for around $1500.
