Audacious Audio

The dogma of separates has long reigned supreme among audiophiles: If you're serious about sound quality, you're supposed to need a dedicated preamp and power amp. The logic goes that separates reduce interference and offer maximum control over your sound. But there's an argument to be made that integrated amplifiers are more practical ... and potentially better-sounding.

The beauty of an integrated amp lies in its synergy. Audio engineers know exactly how the pre and power sections will interact; the two are literally designed to work together. On paper at least, that means optimized impedance matching, and signal integrity that can rival and perhaps surpass separates. How do you know whether a standalone preamp is a great match for a power amp? For most of us, it's through trial and error. It isn't unusual for restless stereo aficionados to own multiple combos over the years, in search of the ideal one. That gets costly.

Then there's the fact that an integrated amp helps declutter a room, appealing to minimalists and people whose living spaces are less than cavernous. Another plus: no need to shell out for audiophile-grade interconnects.

I don't know much about horses, but I've been given to understand that dead ones don't respond to even the severest beating. In light of that, I'll make only this brief statement—Even with the best playback gear of my experience, I don't derive as much pleasure from CDs as I do from LPs.—and move on to a simpler truth: Regardless of what I think, CD players are still a necessity for most music-loving audiophiles.

I've heard a lot of great audio components over the years, but even in that steady stream of excellence, a few have stood out as something special. These are the products that, in their day, set a new standard for performance, and many of them are ones I wish I'd hung on to. Among these products are three preamps from Audio Research: the SP3A, the SP6B, and the SP10 (footnote 1). I know I'm not alone in viewing these models as classics.
