Krell S550i Integrated

Krell S550i Integrated

This is a beast of an integrated amp, much of its 64 lb weight attributed to a massive 1750W toroidal transformer. Requires a 20A outlet. Received many positive reviews.

Original owner, smoke free home. Unit purchased from Music Direct. Selling because I upgraded to NAD Masters streaming DAC/integrated. 

This particular unit is a late-model unit that does not include the iPod input or dock (discontinued). Retains iPod input button on front face (to right of balanced input button)blacked out by manufacturer.

Includes all original packing, manual, remote, 20A power cord, as shown in photos.

Conservatively rated good.
