Yes there is a lot of buzz about them, esp. the 1980 which is selling for a lot of $$.
Coupled with a lot of enthusiasm about the SX line (build quality, excellent tuner, etc.) did the trick for the inflation.
I do own one 1250 and I can attest that these sound very nice. Can drive pretty much anything. One in nice condition and fully functional (including phono) is worh $400 easily.
