May I also offer my condolences. Having recently lost my brother, I know how upsetting and trying these times can be to a family. I just want to make sure you are clear on the DS5R. The unit is specifically for an Alembic Series instrument. It has no other function, period. Similarly, an Alembic Series instrument must have a power supply, either the rackmount DS5R or the older box unit DS5. Without the power supply, the Series instrument will run through batteries like you wouldn't believe. By all means keep the DS5R with the Series instrument.
