If you want a dac that just lets you relax & enjoy beautiful music, this is the dac for you.
here is an extensively upgraded, by me, Stephen Sank of Talking Dog
Transducer Co., Audio Alchemy "Dac in the Box", in it's "Ultra-DAC"
model form, which has it attached to a DTI reclocking unit by a common
front panel. This is the more desirable version of the DITB dac, with
separate left & right channel Analog Devices AD1860 dac chips,
rather than a single stereo AD1864 chip.
The DITB dac unit has
been rebuilt with all Nichicon electrolytic capacitors(the most
bulletproof & best performing lytic cap brand on earth), using
capacitance values HUGELY larger than stock, to massively improve
dynamics, impact & tonal richness. Secondly, large Nichicon caps
were *added* where none existed, close as possible to the power input
pins of the dac chips & analog stage opamp chip, making yet another
dramatic step forward in dynamics & richness. That analog stage
opamp chip has been upgraded to a Burr-Brown OPA2134PA, the most natural
sounding opamp made. Further, the stock analog section's power
regulators have been changed to output +/-12V, rather than +/-5V, to
further improve dynamic headroom & overall sound, and all of the
most important new electrolytic caps have film bypass caps accross them,
under board or where they will fit. Final in-unit change was the
deleting of the badly chosen power input jack, replaced instead with a
hardwired, silverplate copper, teflon jacketed, shielded power supply
This new hardwired supply cable terminates to a
high-current/high-voltage-capable 3pin mini Amphenol locking connector
that plugs into a completely new, custom, maximum-quality, regulated
power supply. It starts with a pure-copper-pinned IEC power cord
receptacle, to a magnetically-shielded power transformer, then to
high-speed/soft-recovery rectifier diodes, feeding overkill-sized
pre-regulator filter capacitors, then the voltage regulators, then
overkill-sized post-regulator filter caps, and finally to the
panel-mounted mini-Amphenol plug.
Thanks to the upgrades,
combined with the nature of the wonderful AD1860 r2r parallel ladder dac
chips, this is a dac that, while not the ultimate in resolution, is one
of the most classically vinyl-sounding dacs you'll ever hear. It will
never fatigue or irritate you ears, and will be a little bit forgiving
of even bad recordings, while still having *BIG* dynamics &
soundstage, and overall wonderfully rich, fluid tone. It is by far
the best dac that Audio Alchemy ever made, far better than the DDEv3.0
or etc., and the best dac you'll find for under a grand.
there is an original model DTI re-clocking unit attached to this dac,
it has not been upgraded(really isn't upgradeable), and will only be
useable if buyer acquires a DTI-compatible power supply unit for it. I
personally regard it as useless, as the upgraded DITB dac is very
insensitive to jitter, leaving the DTI useful only as a device to
convert a toslink optical output to an RCA coax.
