Krell KMA-1800 - MONOBLOCK POWER AMPLIFIER
Stereophile|March 2024
Ever since I raved about Krell's K-300i integrated amplifier after it was released in early 2019,¹ I've wanted to review other Krell products. After spending more than a year and a half (since its prerelease announcement) awaiting the opportunity to review Krell's new flagship mono power amplifier, the KMA-1800 ($73,000/pair), the time has come.

Krell KMA-1800 - MONOBLOCK POWER AMPLIFIER

Both Krell models utilize the company's proprietary iBias technology, albeit in different iterations, and both were designed by longtime Krell engineer Dave Goodman.² In the conclusion to my K-300i review, I wrote, "The Krell ... has the smoothest, most listenable, and most all-of-onepiece sonics of [any] integrated I've reviewed.... There's a round edge to its images that some might equate with the gentlest sprinkling of warmth, but others would describe as listener friendly. It certainly leaves me smiling." I thought it so excellent, and such a good buy for a Roonready streaming integrated with an optional onboard PCM/DSD/ MQA DAC, that I urged a friend to buy one. More than three years later, he's still smiling.

Would Krell's new, far more powerful class-A monoblocks inspire the same excitement? As much as asking the question may sound like the first installment in a made-for-TV soap series, finding out made all the work I did carting these beasts around more than worth it.

The Spin Doctor checks out the Kuzma Safir 9, a superarm from Slovenia.

The British audio scene from the late 1970s through the mid-1980s was pretty strange. Audio as a hobby was a big deal, with widespread appeal to a much younger crowd than today. Audiophiles were guided by a flurry of what my friends called \"hi-fi pornos,\" audio magazines that filled the racks at the newsagents.

Alex goes to Japan

Arriving in Japan from the United States is like being turned upside down. This condition lasts for much of the first week. When I visited in November, the time difference between Tokyo and New York was 14 hours. \"The floating world\" is a term for the pleasure-addled urban culture of Edo-period Japan, but it's also an apt description for the twilit and not-entirely-unpleasant weirdness of first arriving in Tokyo. Everything seems slightly unreal.
