@oldhvymec your setup is fine. A subwoofer or active crossover is by its’ nature a full time connection which needs to be driven by the volume adjusted signal. Use of a processor may be an optional item and if the processor uses digital processing, it is highly undesirable to drive it with a volume adjusted signal. Hence, you need a processor/tape loop which feeds a line-level signal at all times and can be switched in and out at will.
No Tape/Processor Loop????
While tape recorders are of little interest for most users these days, the need for a Processor loop is still with us. If you want to take advantage of an Equalizer, DSP room correction, Phono noise reduction, and of course, a tape recorder, you'll still need a classic tape monitor function. I was using a DEQx processor, and today I use a Sweet Vinyl SC-1 Mini.
There are many high-end preamps which have dropped this essential function: Nagra HD; Luxman C900, C1000; VAC Signature SE (some replaced the Monitor with a logo dimmer!!!) and on and on. The lack of a monitor immediately removes their unit for consideration.
Placing the SC-1 mini in line with the low level phono is compromised on two levels: very low signal, and multiple extra connections when not in use.
Placing a processor between the pre and power amps is unacceptable because the signal out of the preamp may be very low, inhibiting the full range digitial signal processing capability or low-noise performance of the processor.
