Krell KAV-300i integrated amplifier in need of repair. I had the unit serviced September 2025 by Audio 3000.net in Jacksonville for faulty input connections (see attached receipt). The S1, S2 and tape connections now work, but the S3 and balanced connections do not. More recently, some slight distortion has developed in the left channel only. I have decided to go in a different direction with a lower wattage integrated amplifier that is a better match with highly efficient speakers.
