Thanks to all involved - it's a definite improvement.
One oddity I noticed - for Type 'ADC/DAC Interface' and Channels 'Multichannel' only the MOTU 624 shows up. Others I would expect to see like the 18i8, M4 and Xonar don't.
I propose adding 'balanced' as a tag too, since it crops up in people's requirements from time to time.
What are the requirements for data entry? I may be able to help with the above.
