Krell KSA-80B
A used-market fixture that held its value for years. The KSA-80B turns up again and again in dealer classifieds at the same asking price.
Overview
The KSA-80B shows up so often in the back pages of the audio magazines that it starts to feel like a permanent resident of the used market. Throughout the early 1990s, the mail-order firm Audio Classics listed it at a steady $2,700 across multiple catalogs. That suggests both a healthy supply of trade-ins and a seller confident the model would move at that number. The figure appears in Audio's classified pages repeatedly through 1991 and 1992, which is about as clear a signal as vintage buyers get that a component held its resale value.
What the KSA-80B actually is in the broader Krell story is harder to pin down from the surviving documentation. It appears alongside bigger siblings in the same dealer listings - the KSA-100II, the KSA-250, the KMA-200 - but the classifieds only tell us what the amps sold for secondhand, not what made them different from one another. Its place in the lineup is implied by its position in those price lists. Nothing in the available material spells it out.
The amplifier clearly found its way into serious systems. In a 1992 Audiophile piece (Mark Block, Audiophile, 1992, p.98), reviewer Mark Block described himself as a longtime Krell owner, recalling that it was a Krell amplifier that first persuaded him the expense of high-end gear could be money well spent — and noting a friend had once lent him an older KSA-100. That the KSA-80B appears in the same era's classifieds, and that its bigger sibling was the gateway amp for at least one reviewer, places the 80B squarely in the period when Krell's reputation was being built among listeners with demanding speakers.
The used-market record also hints at the practical reality of owning one. The same Audiophile review that mentions the Krell lineage spends considerable space on the Acoustat Spectra 22, a speaker that drops below 2 ohms in the high treble and is described as one of the most power-hungry designs around. These amps were bought by people driving difficult loads, and the surviving examples have likely spent years doing exactly that kind of work.
The Audio Classics catalogs show the KSA-80B trading at $2,700 through 1991 and 1992. That number barely moved even as other components in the same lists fluctuated by hundreds of dollars from issue to issue. Whether the stability came from demand, supply, or simply a dealer's habit of holding a price is not something the record answers.
