Ref 3 Impedence Mismatch HELP please

I've recently discovered I have an impedence mismatch between my Xilica XD 4080 digital crossover and the ARC REF 3. The input impedence on the Xilica is 10K. Which is too low for the REF 3. This causes issues with the sound in the high frequencies and lows. It seems like a Burson Audio XLR Audio Buffer would be the solution but apparently they are not importing them into the country any more.
I was wondering if there is another product or manufacturer that might have a product as a solution or if there is any way to raise the input impedence of the Xilica Crossover by adding caps or resistors as in internal mod.

Any ideas? I know I can always replace the preamp with a solid state unit which I'm contemplating.

As an after thought, wouldn't it be great if the audio manufacturers could at least codify the specs for all audio equipment so that these problems could be prevented? All manufacturs would have to at least hit a target input and output impedence so that all equipment could work together electrically. It seems a no brainer for the industry to develop.

Sgr, pull my old OPs that considered a very similar problem, in some ways even worse than what you have. I used to own a Ref 3 and now a Ref 5. A fellow by the name of Tom Tutay built a custom impedance buffer for me.

Admittedly, it is principally for the Ref 3/5's Main #2 output that powers my sub, not my main outputs. I would call Tom and see if he can custom build something for you. My only concern is that inserting an artifact into your main signal path may cause a different set of problems. But do give Tom a call. He is top drawer. His number is listed on my OPs.
