Widely regarded as one of the best solid state amps ever made, the Krell KSA-50S holds its own against nearly anything of its age – and newer. Nothing about the Krell KSA-50S sounds “vintage” in any way. It possesses all of the qualities that we demand in modern equipment, including speed and attack, clarity, transparency, and a sense of limitless power and unharnessed dynamic contrasts. This particular piece has a few character marks, electronically, it's in top shape.

- Liner Notes
"The KSA-50S is undoubtedly a contender, but its sonic character makes it essential for you to audition it in the context of your own system. Recommended—but news we've just received from Krell could make this moot. Apparently the KSA-50S might be discontinued in September, due to lack of demand: Krell customers appear to be more prepared to spend the big bucks for the bigger amplifiers. Given the '50S's sweet sound and massive power delivery, I feel that this is a pity."

- Packing
- Prepare to be impressed. We have arguably the best packing process around. This piece will ship double-boxed, and fully insulated, taking extra care to ensure there's no pressure against the face. First, the component is first wrapped in 8mil plastic. Then, the unit is strapped to a plate inside an inner box to prevent shifting, and padded on all sides. We then suspend the inner box inside a double-walled outer box using shock-resistant foam corners.
- Shipping
- This piece ships to the contiguous United States for a flat rate of $150, which includes our packaging and our insurance. Of course, we'll ship anywhere in the world, just drop us a line and we'll give you an estimate – even if you're just curious.
- Stock No.
