Krell-Showcase-Review.gifUpgradeitis (a constant search for better picture and better sound) is afflicting more and more of us as DVD has upped the ante in digital picture and sound, and as DVD-Audio and SACD are changing our expectations of digital music reproduction. For those that have fallen in love with surround sound, the search begins for components that create a sense of immersion within a presentation.

Often, that search results in separates: a separate processor and amplifier. Krell has introduced the Showcase line. This line incorporates many of the attributes of their up-market Standard line, but at a much lower cost, and at the expense of very few features. The Showcase line currently consists of the 7.1 Processor, and the Amplifier. For this review, I received the Showcase Processor and 6-channel Showcase Amplifier (also available in 5-, or 7-channel).

Unique Features: Showcase Processor - The $4,000 Showcase Processor uses the same gorgeous casing seen on the Krell DVD Standard. This consists of brushed aluminum on all sides and the top (not on the underside), and polished aluminum rounded ends. The effect is nothing short of stunning, and the only aesthetic shortfall with the Showcase line is the use of black instead of polished silver buttons. This small change did lead to a decrease in the Lady Jacqueline Aesthetic Factor (LJAF, a very rigorous form of the WAF wife acceptance factor test), which had scored the DVD Standard at a 9.5 (10 being the highest), but with the black buttons the LJAF decreased to about 8.5. Fabulous scores to be sure, but the Cartier-like build of these Krell pieces impresses immensely. Both the Processor and the Amplifie deserve to be openly displayed for the eye to savor, and should not be hidden in a cabinet.

The Showcase Processor is THX Ultra Certified, and decodes Dolby Digital, DTS, Dolby Surround EX, DTS-ES, DTS NEO:6, and Dolby Pro Logic II. It also has 9 proprietary music surround modes, and a set of 7.1 inputs for a DVD-A or SACD player. Furthermore, there is an analog bypass option that can be used with any of the analog inputs. The Showcase has balanced and unbalanced connections to an amplifier, as well as a set of balanced audio inputs. There are 7 analog audio inputs, and a tape NCR set of loop inputs. There are four each of coaxial and Toslink digital connections. Video connections consist of 4 composite inputs and 2 composite outputs, 4 S-Video inputs and 2 S-Video outputs, and three wideband component inputs (80 MHz bandwidth so high-def signal switching is not a problem) and one component output. The onscreen display is available on one composite and one S-Video output, as well as on the component output (unfortunately not in progressive mode, just interlaced). There are also 4 12-volt triggers. The Processor is software upgradeable, and this can be accomplished using the RS-232 port on the back. This capability is extremely important, as it provides you not only with fixes, but also access to new or changed decoding formats. The back panel has all of these various connectors laid out in an orderly fashion, making hookup relatively straightforward and easy.

The front panel has the Showcase logo above the central red LED display with input device selection buttons to the left, and processing mode buttons to the right. Right below the latter are the individual channel trim buttons, as well as the level buttons. All the LEDs are red except for the power LED which is blue. Right below the display are the recall and save buttons, which are used for the Room Equalization (EQ) feature. Overall the effect is quite pleasant, but the LED display is a bit difficult to read from a distance.

The remote is of the small, slim variety, and controls many functions. It is not programmable, as Krell seems to (probably correctly) assume that most prospective clients will have some sort of master controller. I happen to like Krell's small, thin remotes, so it was not a negative in my book.

Installation/Setup/Ease of Use: Showcase Processor - The on-screen display is fairly straightforward, and the Showcase is very easy to set up. Analog, digital coaxial/Toslink, and video hookups are all assignable, allowing for a tremendous amount of flexibility. In fact, you can have two different channels using some of the same connections, as I did when I connected my digital cable box. Since there is no scaling on this box, I would use its S-Video output for regular television, and component outputs only for high-definition programming. I was able to assign the same digital connection to two separate channels with different video inputs making switching back and forth easy. There are, of course, the requisite trim, time alignment, level controls, and the subwoofer crossover can be set to 40, 60, 80, 100, and 120 KHz.

Final Take: Showcase Processor - After hooking up everything, and allowing appropriate break-in time, I started my listening by using it in analog bypass mode for 2-channel and multi-channel music to get a feel for the sonic signature. The Krell is a very accurate processor, and has a smooth neutral sound with occasionally slightly sibilant highs, and a fast dynamic low end. I was especially struck by the delicacy, crispness, and smoothness of the midrange: it provided vocals and string instruments with incredible texture. Every texture in the midrange is crisply audible, making for a very dramatic presentation. The soundstage is very large and deep, and the presentation is slightly laid back as on the DVD Standard (which uses the same DACs). More of the same was found on using the Showcase as the processor for decoding music, using my player as a transport, and its overall 2-channel performance was excellent, with a presentation
that was slightly more laid back and expansive than my Marantz player. The overall character of the Showcase Processor's sound can best be described as dramatic and even passionate--characteristics which are very appealing indeed.

Performance for movies is also impressive, with excellent steering and clarity of vocals. I found the crispness of the midrange made watching movies a joy, and THX processing took care of the occasional bright soundtracks. Pro Logic II is wonderful for watching 2-channel sources such as television, but although PL II is fun for listening to 2-channel music, I still find that I prefer good old regular stereo. The LED display turns itself off after a period of time--great for darkened rooms, and re-lights with the press of a button on the remote. The processor makes an audible clicking noise when switching between sources, giving a real machine like feel to the unit, which seems to fit its metallic, precision image.

One of the features that sets the Showcase Processor apart from the pack is the Room EQ feature. This is not your average old equalizer, as it does all of its equalization in the digital domain. This is a first for a home processor, and allows for compensation of room and equipment problems. Room EQ consists of four memory settings that you can set for different conditions such as movies, music listening, games, etc. There are six different filter types that can be applied: Notch, Peaking, High Shelf, Low Shelf, High Pass, and Low Pass. For each of these filters, the frequency, shape, and level can be configured. Room EQ is an extremely powerful tool that allows you to change and adapt the sound of the unit
to your particular room and listening tastes. It is a complex tool that is not thoroughly explained in the owners manual, but Krell will soon put out a special guide just for this feature. Krell should be congratulated for bringing such powerful flexibility to a home processor, and in the time that I spent with the Showcase Processor, I feel I only scratched the surface of what Room EQ can do.

Unique Features: Showcase Amplifier - Now, it was on to the Showcase Amplifier to complete the dynamic duo. The Amplifier has the same brushed aluminum casing as the Processor, but the front only has the logo in the center and power controls/LEDs on the left side. It is also a very attractive piece cosmetically, and is rated at 125 watts per channel at 8 ohms which doubles to 250 watts at 4 ohms. The amp weighs a solid 58 pounds, and has vent holes on top and bottom. The back panel has both balanced and unbalanced connectors for all channels, and solid, well-spaced binding posts for speaker cable hookup. One of the great features of the amp is that it can be upgraded with extra channels, so if you buy the 5-channel version and then migrate to a 7.1 system, the amp can be upgraded by the factory for the extra channels. The amp can be connected via trigger to the processor. I would not be fooled by the relatively "low" rating of 125 watts/channel on the amp, as what matters as much as wattage is the ability of an amp to supply current. Krell amps have always been exceptional at this, and this characteristic allows for excellent control of speakers that are more difficult to drive. This shows up in the ability to double wattage output as the impedance is halved. Bottom line: this amp can drive difficult speakers and fill a good-sized room with copious amounts of sound.
