ASi OTM Low Impedance Battery Supply
You will need to ship your unit in for the OTM battery supply
retrofit as we will need to mount connectors and install wiring, etc
Other mods should be done at the same time as the OTM such as
the Bybee Music Rails, etc.

Pricing:
Starting at $695 to $795 for most gear. This battery supply could
be designed to run more than one component. Most applications
are
$695-795 and the more sophisticated designs are $995-2500.


Turnaround is 1-3 weeks depending on the peice of gear.

International orders are welcome, the cost for shipping outside of
North America is generally around $160-200

The ASi OTM ("Off The Mains") Low Impedance Battery Supply is a sonic gamechanging "retrofit add-on" modification upgrade
that bypasses specific critical power supply voltages that exist inside your Hi-Fi audio gear and replaces them with ultra clean battery
power instead.  For example, in a CD player/DAC/Audio processor, we battery power the critical audio processing circuits such as the
DSP circuit, DAC chips, upgraded master clock (such as Dexa Neutron Star), analog output stage voltages (if necessary). The rest of
the unnecessary circuitry such as for the remote control, front display, etc is run from the units internal power supply as there is no
need to battery power these circuits and they would just introduce more load and noise. In some situations (such as Esound CD-E5,
Marantz SA-8005/SA-11/SA-7, Wadia 170/171i, PS Audio GCA preamp, etc), our ASi OTM can
COMPLETELY power your entire unit
(no AC mains!) for the best sound possible.    This OTM supply can be used with computers to power sound cards or other neat
custom applications you might have. In most applications, you will turn on the OTM supply first and then the component.   This
upgrade is much more cost effective than buying AC mains power conditioning products or expensive power cords. For a
fraction of
the cost
of some of the ac conditioners on the market, you can get this battery supply mod done and have about 50x the
performance over using the noisy ac mains of 2016 (there are alot of cell phone/table/computer chargers on the grid throwing noise
back onto it), so the OTM is the best sonic solution to remove yourself from all this garbage that is muffling up your audio
performance. The OTM has
built-in autocharging, included is a external digital timer and power cord. The digital timer is preset
to recharge the supply every night (or your time preference) so the supply is always topped off and will never run down or out.  No
maintenance! Set and forget! The digital timer acts like a high voltage switch, so there is
never any AC inside of the battery supply
while you are listening for the quietest and best audio performance. The OTM enclosure is made from EMI/RFi reduction aluminum
and is further RFI taped internally to reduce resonance along with a wooden base floor for resonance and stability for shipping, the
color choices are Black or Gold. The
standard enclosure size is 12"W x 12"L x 5"H (however they can go as big as 19"W x 25"D
x 9"H
for custom use for many batteries for powering multiple components) so this supply can mount below in a rack shelf. The
supplyif used correctly should last easily 8-10+ years without needing to replace any of the batteries. We have built hundreds of
custom OTM supplies starting since 2006 and are still running today into 2016 on the original batteries.   We sell and ship these
WORLD WIDE. If your located in a 230V country, we can supply you a 230 to 115 volt step down transformer so this external
batterysupply will work fine.
