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.
