Congratulations on your purchase of what's probably the highest perfor-
mance per cubic-inch audio device on the planet! Your new Micro Amp
will take up very little space on your desktop, but it will completely fill the
space right between your ears with glorious music.
Because they are both functionally identical, this manual covers both
the Micro Amp and the Ultra Micro Amp. The only difference between
amps is that the excellent TI 134 op-amps in the standard Micro Amp are
replaced with the amazingly excellent --- and shockingly expensive --- TI
627 op-amps. Other than that both amps are constructed using the same
outstanding quality metal film resistors and poly-film caps.
Enough with the front of the manual, already! Read on, set it up, and go
have a great headphone listening session. And for those moments you
may not need headphones, don't forget to use the pre-amp out on the
rear panel as a source for desktop speaker power amp or self powered
