I have a like new Ultra Preamp and 2 SE84ckc amps I need to sell as I am having to sell my entire system due to old age and hearing problems. Prices are $2000 for preamp and $600 for each amp.  This equipment has less than 50 hours of listening on them.  I have a lot of other equipment to sell, but thought I would start with these items first.  The speakers are ZU Audio dirty weekends about a year old with 5 hours on them and the black cube center channel speaker. All are black. Main speakers $1000 and cube $250. You can call me at 785-293-2408 Steve.  I am a retired Electronics Technologist.
