Testing chain:
Pioneer DV-343 (CD-R w/RMAA signal) line-out to Behringer UB802 line-in,
UB802 balanced out to [Jensen PI-2xx] to Sony MDS-JB930 line in (live monitor)
SPDIF optical out to HHB MDP500 (live monitor), USB out to PC.
Sampling mode: 16-bit, 44 kHz
Data is with and without Jensen PI-2xx audio isolation transformer inline
Results show transformer adds essentially no measurable distortion at 16 bits.
