Solid State Power Amp Reviews

There seems to be an inexhaustible supply of amplifiers; it's hard to choose which ones to review. Big-name operators are difficult to ignore, while smaller outfits often complain of neglect. In the case of a new and moderately priced introduction from Krell there's no need to find excuses: it's available, it's likely to be important judging from this company's track record, and we'd all like to see just how well it performs.

This review features the KST-100 stereo power amplifier. Initially this product was differentiated from the more expensive Krell components by having an all-black livery. However, as customers showed a preference for Krell's traditional anthracite finish, the KS series is now also available in this finish.

Have I told you about my objectivist friend—the left-brain audiophile who puts a lot of trust in measurements? He has a high natural intelligence and is an extremely experienced listener, but once he knows a component doesn't measure well, he can never again experience it impartially.

I don't want to embarrass my friend, so in this story I will call him O., for Mr. Objectivity.

Dinesh Paliwal, CEO of Harman International Industries, was addressing engineers and the audio press in a crowded conference room at the opening of Harman Luxury Audio's new Engineering Center of Excellence (ECOE), in Shelton, Connecticut. Paliwal singled out as the ECOE's first beneficiary the Mark Levinson brand, with the goal of revitalizing it as Harman's flagship marque. (Other brands in the HII stable include Harman Kardon, Infinity, JBL, Crown, AKG, Lexicon, and Revel.) To achieve this, he gave the ECOE team access to Harman's R&D budget of $400 million; brought on Todd Eichenbaum, formerly of Krell, to be its Director; and hired 11 more engineers.

If we had been asked some time ago to describe our "dream amplifier," chances are we would have described the Crown DC-300. Designed originally as an industrial device, it was made available as an audio amplifier rather as an afterthought. But if that roundabout approach is necessary to produce an audio amplifier like this, so be it.

I've known Peder Bäckman, international sales director for the German firm Audio Video Manufaktur GmbH (AVM), for many years, ever since he worked with Electrocompaniet. When I told him that I was looking for products to review in the reference system in my new 20' by 16' by 9' music room, he invited me to browse AVM's large catalog and see what tickled my fancy. In consultation with John Atkinson, it became clear that AVM's largest, most powerful monoblock amplifier, the Ovation MA8.2 ($29,990/pair), seemed a good fit.

I still remember reading about my first Mark Levinson product 14 or 15 years ago. It was a preamp. The model number escapes me, but it sold for over $2000. It was soon followed by the JC-2, designed by John Curl, which was a bit less pricey but still astonishingly expensive for a mid-'70s preamp. We've come a long way since then. The man, Mark Levinson, left the company that bore his name in the early 1980s and founded a new company, Cello. The company Mark Levinson became the core of Madrigal. It is a mark of their continued dedication to uncompromising high-end products that their bread-and-butter line remains the high-priced Mark Levinsons. They no longer have the Rolls-Royce of the audio market to themselves (in their early years, they made the never exactly inexpensive Audio Research products—ARC was certainly a contender for the same title—look like bargains), but they are certainly a leading player.

Has it really been more than seven years since I reviewed Bel Canto's REF1000M monoblock? According to the Bel Canto website, that model, based on Bang & Olufsen's ICEpower class-D modules, is no longer available. But now, like so many manufacturers, Bel Canto has adopted for its new models the NCore class-D module from Hypex—although the REF600M monoblock ($4990/pair) is not Bel Canto's first product to use it . . .
