"First of all, just to let you know, I am very happy with the amps and preamps that you built for me.
Alot, of compliments from friends, visitors and family members. Especially from my nephew just graduated from WESTPOINT
07, he said he never see a tube amps before. Some old folks from Los Angeles was familiar with the tube amps and he
really likes the warm sound especially with the Klipsch Quartet Speakers." - Alex M. Olay
