But when the phono cartridge of choice is a moving-coil (MC) type, which generates even less voltage than its moving-magnet (MM) and moving-iron (MI) friends, even more gain is required. This presents the user with an additional choice: he or she can select from among the many standalone phono preamps that offer sufficient gain, or augment an existing phono or full-function preamp or integrated amplifier with a phono step-up transformer, which boosts gain passively, without using tubes or transistors.
In my previous episode, I threw down the gauntlet: Can the world’s best headphones hold up to the world’s best loudspeakers in a perfectly-treated room? Of course we know that headphones image completely differently from loudspeakers. The transient impact of transducers lodged on your ears is distinctly different from loudspeakers at 9 foot distance. The loudness ratios of forward and distant elements, direct and reverberant sound are also different between phones and speakers. But we certainly can compare the tonal accuracy of the two presentations.
The Chinese company Auralic Limited has been pushing bits around for seven years, releasing a half-dozen streaming and network devices. Their newest, the Altair, combines in a single package the functions of a DAC, streamer, and headphone amplifier with volume control, allowing it also to operate as an all-digital-system preamplifier. Just add power amp and speakers.
