Over the course of several months, during which time I auditioned the Vacuum Tube Logic TL-5.5 tubed line-stage preamp with a variety of power amps and loudspeakers, I began to reassess many long-held notions about the "characters" of solid-state and tube components. Sometimes the TL-5.5 revealed its musical pedigree with all the midrange juiciness and sublime textural detail that one traditionally associates with a triode front-end, while at others it evinced a level of focus, transparency, and frequency extension I more readily associate with solid-state purity—all in a stylish package featuring a remote volume control and a full range of performance enhancements that belied its affordable price.

With this review I conclude an audiophile's progression through the price/performance ratios of three very musical solid-state integrated amplifiers: the NAD C370 ($699, reviewed in January 2002), the Arcam DiVA A85 ($1499, February 2002), and now the Simaudio Moon i-5 ($2595). In the process I was fascinated to hear how each amp recommended itself to its targeted price point. Likewise, it was most instructive to hear how they spread their compromises around. With a rough doubling of suggested retail price from the NAD to the Arcam, there was a degree of sonic refinement introduced. However, the leap in improved sound from the Arcam to the Simaudio was more significant. And in quantifying the benefits another $1000 worth of enhancements can confer, I discovered what constitute real high-end bona fides.

NAD has been out there on the leading edge of entry-level high-end sound long enough that some audiophiles reckon they invented the category. Sure, we should give serious props to the likes of Creek, Rotel, Musical Fidelity, Arcam, Denon, and Parasound, all of which have made significant contributions to the musical aspirations of budget-conscious pilgrims. But I continue to harbor warm feelings about my last extended visit with an NAD component: the inexpensive yet supremely musical L40 CD Receiver, which I reviewed in the June 2000 Stereophile.
