It seems like a lifetime ago I reviewed the Karan Acoustics KAS 450 stereo amplifier. My conclusion was "This is an amplifier I could live with for the long haul," and was planning on adding it to my system. If not for a train wreck of an experience with a speaker manufacturer who took a $20,000 down payment for new speakers after I sold my reference, I would have happily added the KAS 450 to the system. Failing to fulfill his promise to deliver my new speaker in eight weeks, I had to sell one of my amplifiers in order to fill in the speaker gap left for the next 10 months.
