Integrated Amp Reviews

I hate all those automobile reviews that go on and on about a car's design aesthetics. C'mon, I can see what it looks like, even if only in the pictures. Just tell me things I can't appreciate without a run on the Autobahn.

Over the years, I have used and enjoyed in my audio system large, single-purpose components. Each of these chassis has had but one role: preamplifier, amplifier, digital-to-audio converter (DAC), etc. I guess I've been just a little suspicious of products with multiple functions crammed into a single small chassis; I've figured that the designer may have cut a corner that could affect the sound.

July came in this year like September: cool, crisp night air and bright, clear days. The humidity and temperature remained low throughout the week I spent setting up the Denon AVR-4800 surround A/V receiver. So, crouched down behind its crowded rear panel, wiring up eight loudspeakers and multiple inputs, I wasn't sweating from the temperature. Launching the new multichannel Denon AVR-4800's surround audio-visual system required hard work, trial and error, and an emergency trip to the UPS terminal in the Bronx. While there were great musical pleasures ahead, the path to music-surround knowledge was rougher than I ever imagined it might be.

The one thing I've liked about designer Mike Creek of Creek Audio as much as his design talent is his predictability. I've been following his integrated-amplifier designs for nearly 20 years now, having reviewed, in sequence, the CAS4140s2 (for another magazine), the 4240SE (Stereophile, December 1995, Vol.18 No.12), and the 5350SEhttp://www.stereophile.com/integratedamps/327">5350SE; (March 2001, Vol.24 No.3). In each case, I was sufficiently impressed with the review sample that I bought it and made it my new reference in my second, affordable system. The predictable part comes from Creek's traditional nomenclature: an "s2" or "SE" (Special Edition) designation has always denoted a modest upgrade, and a numerical uptick in the model number a more significant upgrade, the level of significance denoted by the specific digit being increased. Hence, the update from 4240 to 5350 is intended to indicate a greater improvement in sound than the update from 4140 to 4240.

Older audiophiles remember the splash NAD made in the late 1970s with the introduction of their 3020 integrated amplifier ($175). Ridiculously cheap, it looked graceful and sounded warm, inviting, and holographic. Removable jumpers between the 3020's sections permitted enthusiasts to determine whether the magic resided in its preamp, its power amp, or in some synergy of both.

As you read this, are you listening to your stereo? Whatever the music, what you're actually hearing is your public utility's AC as modulated by your power amplifier. No matter how good the gear, the final result can be only as pure as the power feeding your components. Unfortunately, plenty of sonic schmutz usually comes along for the ride.

The Rega Couple interconnect ($150/1m pair) comes in a plastic pouch rather like a Ziploc veggie bag—just the pouch and a printed card. How much could the packaging cost? Ten cents?
