Hi Phaelon,
I agree with Misskuma, the CJ will probably assert it's own approach to sound over the Art Audio Jota. I've tried several preamps ahead of my AA PX-25 and the sonic influences are readily apparent. I ended up going with a passive transformer volume control to retain the transparency and tonal purity.(not suggesting you should do the same)
But, there's no way to know until you try. Test it out, but I would highly suggest using a preamp intended to be used in a SET system. Or, at least one that was designed with SET in mind as an option. There are certain unique aspects or traits (and highly desirable ones) that just are not existent in many PP amps. It is important that they are preserved.
There are plenty of choices significantly different from CJ. Consider an Art Audio, Shindo, Air Tight, etc.
Of course, any well-designed, well-executed, linestage should perform well in any system and let through everything preceding it. I think most of us will agree that there are many that fall short of this.
