Processor input / external pre amp

I have a Kinergetics KPS 2 with one input. Because I am in need of more inputs, is it possible to add my Reference Line passive pre amp to the KPS 2 to enable more input access while still maintaining the sound quality of the Kinergetics unit. Thank you in advance.

You can use an input selector switch if you don't mind the manual select for the KPS versus the Line level pre-amp. That's what I did.
47 Labs Input Chooser is a quality product at a reasonable price. I understand that Jena Labs will make an extreme selector switch at an extreme price. This is the best alternative that I have found.
