James,
now you got me confused...
The C (consumer) Series was designed with a non-rack mount application in mind. So it is avialable in 17 inch faceplates with no handles or 19 inch with handles.
The 19 inch Pro faceplates are required if in fact you wish to rack mount the amplifier.
If a PRO panel (which is to my knowledge the same as the non-C-series SST front panel that was monted on all SSTs before the C-series became available) can be mounted on a C-series SST, why can't a C-series front panel be mounted on a non-C-series SST amplifier???
I just acquired a used 14B SST (non-C-series) with the 'wrong' color. So an investment in a black face plate is necessary. I would, of course, prefer to mount the C-series front panel - just because of the better looks...
BTW, has Ann Forbes been with you on the CES? I had sent her an e-mail on Jan 6, asking for a quote for a few things (dress panel kit 14B SST, box/foam for a 9B ST, rack mount ears for BP25/SP-2PRO Upgrade...) but haven't received a reply until now.
Thanks!
Markus
