Lyngdorf TDAI 3400 Digital Crossover

Has anyone used the digital crossover available in the Lyngdorf 3400 to bi-amp a pair of speakers via there binding posts. If so was the benefit worth the extra cost of a second amp and cables.

I have a pair of open baffle Jamo R909 whose binding posts crossover to Bass/Mids and Tweeters and was thinking of using the amp in the 3400 to drive the tweeters (a bit of overkill) and a pair of Bel Canto Ref 600M mono blocks to drive the Bass/Mids.

The Jamos have twin 15" bass drivers in each speaker and need to be tightly controlled to sound their best.

Thanks in advance,
