Krell KSA-150
What survives on the Krell KSA-150 is mostly Krell's own advertising pages in Audio, not a full independent review. The record is thin, but it is consistent. In Audio (October 1990, p.183), the KSA-150 appears in Krell's line-up as a "Stereo Balanced Amplifier," alongside the KST-100 stereo amplifier, the KSL preamp, a KSP stereo preamp, and the MDA-300 mono differential amplifier.
A few months later, Krell's own page (Audio, January 1991, p.91) described the KSA-150 as designed to deliver the superb performance of the KSA-250. It listed the headline spec: 150 watts of Class A per channel into 8 ohms, doubling into successively lower impedances up to 1,200 watts per channel into 1 ohm. The same page noted that it followed Krell's tradition of modular component design.
- Stereo Class A power amplifier, balanced design
- 150 W/channel into 8 ohms; 1,200 W/channel into 1 ohm (Krell's spec)
- Advertised in Audio from late 1990 through early 1991
