FS: Krell KAV-400xi Integrated amplifier with Theater Throughput
I purchased this in 2011 as New, Old Stock from a Doctor out in California who had a number of these in storage and I have been using it as my main amplifier ever since, first with a Cullen Circuits modified DLIII, then with a PerfectWave MKII and most recently with my DirectStream DAC. Used it mostly as a power amp with the Theater Throughput and balance interconnects from the DirectStream. More than enough power to drive my pair of elderly Legacy Focus speakers.
Have never had any issue with this unit until recently when I started to unwind my collection of stereo gear as part of my Retirement / downsizing plans.
Normally, this amp has been dead quiet but recently noticed a bit of a hum at the speakers after the unit was left on for several days without any input from the DAC. The hum seemed to be a bit louder coming from the left speaker than from the right. I disconnected the interconnects from the DAC to the amp and the hum was still present. I disconnected the amp from my Premier Power Plant and plugged it directly into my Soloist outlet at the wall. Still a bit of a hum. Unplugged the unit and let it cool down overnight ( it runs warm but never hot ) and plugged it back into the Soloist. The hum was still there but at a much lower intensity, noticeable on the left channel but almost negligible on the right. I took the Krell out of service and replaced it with an older Hafler 9270 amp. Turning the amp on, there was no hum heard at the speakers which more or less confirmed that the issue was with the Krell amp.
Had all intentions of trying to sell this amp before this issue surfaced, obviously at a somewhat higher price point.
Hoping there is someone out there who appreciates the build quality of KRELL products, maybe has some idea of what might be wrong with this unit, can fix it and return it to a desired status either for their own use or for resale. As stated in the topic description this unit was made in the USA.
I don’t have the time to send this unit off for servicing and am trying to downsize so am offering this amp for sale “AS-IS”.
