Really nice matched B&K Components pair, Pro-5 pre-amp and ST-140 power amp. Sweet tube-like sound. Pro-5 has a good phono stage. Used these with LaScalas and Choruses. Great presence and soundstage. I moved last year and retired. Now in a smaller house. Had to sell the LaScalas and now the amps. Honestly, the B&Ks sound as good to me as the Scott LK-72 tube amp refurbed by Craig Ostby that I also used with the LaScalas. I have seen great reviews for the ST-140. It is a solid unit. I have also seen some for the Pro-5 complaining of problems with the RCA connectors, but I have had no problems at all. Listening in the passive mode on the Pro-5, bypassing the gain stage, the sound is excellent. $200 for the pair. Charlotte, NC area. I will be glad to ship and will pack them like armor plate for safe arrival. Thanks.

B&K Components pair, Pro-5 pre-amp and ST-140 power amp, really sweet sound, reviewed as sounding tube-like and they do, used with LaScalas (http://forums.stevehoffman.tv/threads/the-80s-wonder-or-how-i-bought-a-b-k-st-140-amplifier.226042/) - $300 for the pair

Heard really good things about this pair. "Tubelike" was just one of the positive descriptions.

Good luck with your sale,

Bill
