Is your system still Analog if you use any form of DSP?

If you have a 2 channel analog system, there's no reason to use DSP to integrate subs. You can if you want to, but your best option is to get a pair of subs that are intended for music, not home theater, and use the speaker cable inputs to get the signal to your subs. If you have a HT system, this may not be your best option, but it sounds like you are just listening to music.

I do not loose sleep over anything.  Just a question.  I would think that adding 4 RCA connections and another device in the signal path would have more adverse effect that the DSP processing itself.

I have two subs integrated with my Source Point 8s.  I only use the cutoff in the subs to set their level connected to the second pair of pre outs on my preamp.

It was just a general discussion question.  I have a pure analog section from my LP12 to preamp and a digital path to preamp from my Denafrips Venus where my Transport and streamer are handled.

The reason I asked is the point that i read articles that talk about DSP for room correction and sub integration without regard for those that are Analog purists.

The castles we build in our heads. 

Well, the articles sound like.they "talk about DSP for room correction and sub integration".."Analog purity" (with a capital A, is there some certification available?) is a different topic. 

I think some sort of hardware/processing "purity" of any sort is the tail wagging the dog, unless that purity is the goal and how it sounds is secondary..
