![]() ![]() a correctly designed interface transformer does not. Resistors and capacitors are imperfect in the sense that they all alter the relationship between amplitude and frequency. ![]() That’s something Audio Note has been doing for a number of years, beginning with their top-of-the-line M10.Īs the company’s Peter Qvortrup puts it, transformer drive “linearizes the entire dynamic envelope of the music passing through the preamp. Arguably, though, the M2B’s greatest design distinction is that it speaks to the world through a pair of output transformers, just like a tube amp. ![]() The M2 has come up for redesign, resulting in a product that not only nips at the M3’s heels but comes close to tying the race: the M2 Balanced, or M2B.Īs its name implies, the M2 Balanced can drive the balanced inputs of any amplifier so equipped (although it isn’t designed for balanced throughput: all of its signal inputs are single-ended). Now the Audio Note designers have worked their way back through their preamp line-which, incidentally, peaks out at the mighty M10 ($40,000 without phono: go ahead and wince). Then came the very upmarket M3 ($7500 with phono), which took all those strengths and presented them with a level of musical ease and rightness I’d never heard from a preamp before. I tried the somewhat upmarket M2 ($2695 with phono), which sounded like a more refined version of the M1. (Newcomers, please don’t wince: That’s awfully cheap for what it was.) And the M1 cost only $1250 at the time, with phono stage. The first time I heard an Audio Note preamp was seven or eight years ago, when I sampled their entry-level M1-a refreshingly musical thing that brought the same kind of color and drama to preamplification that Audio Note’s more famous products brought to the driving of speakers. ![]()
