Oade Brothers Audio Offers two mods for the UA5 !
# The first mod enables the digital coax and optical outputs for stand alone operation without a computer. It can also be used with a computer to output data simultaneously to a both coax and optical digital connectors, in addition to your computer ! The mod disables the digital output from a computer to the UA5 via the USB port, so you cannot send data from the computer to the UA5 on the USB buss. This does not affect your ability to record with it, only your ability to send data from your hard drive to the UA5 via USB.
# The second series of MODs add an analog input rebuild. This replaces the input capacitors, which are SMD electrolytic ( higher distortion and noise) with SMD film caps ( lower distortion and noise) as well as the input Op Amps. We use very high grade, very low noise Op Amps for this, chosen by ear for a natural and pleasing sound. Three versions are available to suit the tastes and needs of any recordist. The first is the Warm MOD © which gives the UA5 a warmer sound, with better depth and high frequency character. Tube like in character with a huge soundstage that satisfies the tube lover ! The second "flavor" available is the Presence MOD©, chosen by ear for a maximum clarity and detail. This mod gives the UA5 a more "up front" sound, with better presence and high frequency detail. The third version available is the Transparency MOD©, chosen by ear for a neutrality, speed and detail. This mod gives the UA5 a very fast and clean sound that accurately conveys the character of the source. All three MODs disable the 1/4" inputs on the front panel, leaving the front panel XLR's and rear panel RCA inputs intact. For computer only use, any of the three analog input MODs can be ordered without the digital output MOD.
# We also offer a PLUS MOD that can be applied to any of the three analog input MODs. This further reduces noise and distortions in the UA5 by improving the DC supplies, phantom power and RCA inputs.
