The Golden age

Why isn’t Krell building real power amps anymore?The Krell FPB-700cx cost $14,000 when it was available a decade ago. This 180-pound monster had two 4kVA transformers, and a fully regulated output stage with banks of transistors. There is no conceivable speaker this powerhouse could not drive into oblivion. Its 700Wpc-into-8-ohms output doubled down all the way to 2 ohms, at which it reportedly could produce over 6000W before it quit. The top Krell amp now, the Duo 300 ($8500), produces 300Wpc into 8 ohms, weighs 70 pounds, and has fans to cool it instead of the massive heatsinks that all Krells used to have. The transformer is 750VA. What gives? Am I the only one who sees the new Duo models as “home theater” amps designed for custom installers? They’re not what founder Dan D’Agostino once envisioned, and what built the company: audiophile powerhouses, a man’s amp, the baddest dudes on the block. If you’re listening up there in Connecticut, please rethink this and tell us that there’s a second line of amplifiers coming that will be the real deal. To the Krell management, remember what Stephen Covey said: “The main thing is to keep the main thing the main thing.” What happened to the Mark Levinson brand? There was a time, not so long ago, when the name Mark Levinson was revered. Whether amplifier, preamplifier, or digital component, when the classic ML logo preceded a model number, you just knew that it would be a contender for the state of the art. Remember the No.30 digital-to-analog converter? How about the epic No.20 and No.20.5 monoblocks? These products were icons, and represented the aspirations of many audiophiles. Lately, not so much. While the Levinson brand still lives, no one I know speaks of it in reverent tones. The No.53 amplifiers have gotten pretty good reviews, but these days I hear nothing of their digital products -- like Krell, ML now seems to make more “home theater” amplifiers than anything else. Maybe the company’s products stillare up there with the best, but ML’s messaging isn’t that good -- it often happens in a too-corporate environment. Or maybe the team of engineers Levinson had back in the Madrigal Audio Labs days are long gone, and there’s no one left at the Harman Luxury Audio Group who can design really great stereo components. I wish I knew what the deal was, because I miss this iconic brand, and often wonder if it’s ever coming back.
 if you can shed light on any of this, let ’er rip.

Audiolabyrinth, I too lament the direction you've outlined. The founders of the above mentioned companies have moved on, leaving the direction of their companies to profiteers'.
 Like many things in life, fashion is cyclical. I imagine that when the economy improves we might see more big iron, though the future of big power might come more from Class D.

In the interim, smaller, lighter amps have the advantage of economy of scale (materials, case work, packaging, shipping, etc.) with corresponding higher profit margins. Smaller, lighter amps with the added feature(?) of adjustability (tube rolling) lends itself to hobbyists who like to tinker for the sake of it, and/or who are more likely to buy if it's more convenient to do so. To be honest, even as one who appreciates big iron, I don't look forward to the expense and inconvenience and shipping(!) of swapping out these heavy pieces.

Those that can afford such gear are often times now buying for multi-channel HT systems that makes big iron even more challenging to deal with.

I don't agree with the notion that there is a ceiling on the amount available power that can't be exceeded without compromising quality.

Class D has pretty much done in big iron monster amps of days past.  Some still linger but fewer than ever will find a need or want.   It is undeniably progress to be able to make similar power amps smaller way more efficient and in many cases cheaper as well.

Great post everyone,  but I do not agree that big powerful amplifiers are dinosaur's,, I'm really speaking about why is krell,  Mark Levinson and some others are doing what they are today,  anyway,  here is proof that amplifiers of this type is here to stay,   PROGRESSION MONO AMPLIFIER
The Progression mono amplifier is the largest and most powerful Dan D’Agostino Master Audio Systems has made to date, delivering 800 watts into 8 ohms, doubling to 1,600 watts into 4 ohms and doubling again to 3,200 watts into 2 ohms. It employs a fully complementary driver stage, beefed up with 84 output transistors, a 4000 VA power supply transformer and 400,000 microfarads of power supply storage capacitance.
The iconic look of the Momentum amplifiers’ power meters, inspired by the elegant faces of classic Swiss watches, continues with the Progression series. The Progression mono amplifier features a new meter design with a 270-degree needle swing, driven by a high-speed ballistic circuit that enhances the meter’s responsiveness. The longer swing allows the needle to cover the amplifier’s entire output range.
The venturi heatsink design premiered in the Momentum amplifiers has been adapted to the cooling needs of the Progression mono amplifier by adding a second row of venturis to each heatsink. Each heatsink is milled from a single, 48.5-pound (22-kilogram) aluminum billet.
The Momentum series amplifiers focused on combining high power output with a relatively small form factor. The Progression mono delivers extraordinary power in a larger package with the ability to drive speakers to lifelike levels. The Progression circuitry borrows greatly from the flagship Momentum to be a perfect match for virtually any speaker. The audio signal path throughout is discrete, balanced, and direct coupled. Advanced protection techniques shield the amplifier and associated components from any unexpected anomaly. Like the Momentum amplifier, the Progression circuit boards are executed with through-hole construction for the best sound quality and durability. Like all our products, the Progression series components will be built by hand in our Arizona factory.
The Progression mono amplifier is projected to ship in the first quarter of 2016 and will be available in silver or black finish.

Jeff Rowland currently makes a "beast" of an amp. I think the retail is around $40K.  Clearly, some of the legacy companies have not slowed production. The big question- whom is buying these mega-buck products?
