Exactly.  As I stated, you can't get away from the delay in the filter. 
I was describing *additional* delay beyond that of the filter.

If the system is sampling at 48 kHz, a sample-by-sample architecture 
will have 20.8 *micro*seconds delay before the subsequent filters, etc., 
see the signal.

If it is block based, and the block size is 1024 samples, then at the 
same 48 kHz sample rate you'd have 22 *milli*seconds of delay before the 
subsequent filters, etc., see the signal.

Sorry if I wasn't clear on that.

Enjoy!
