In very general terms, bi-amping reduces the load placed on each ‘leg’ of the amplifier by the speaker. So in theory, the amp has slightly more headroom than would otherwise be the case. Whether you perceive this as an ‘upgrade’ or not might be debatable as results from bi-amping seem to vary.
I have no direct experience of bi-amping with Roksan kit but I used to run a bi-amped Meridian set up. With respect, I think you’d be heading down a blind alley by purchasing either of the amps you mention and running them with your current integrated amp. The FR-5’s are pretty demanding and I’d go with using monoblocs instead and when funds allow swapping out the integrated for a dedicated pre-amp. That is actually where I experienced the biggest gain in my old set up.
You may be looking for an ‘easy’ upgrade but if I were you I’d be saving for longer and getting the pre/mono’s in one go.

I listened with the integrated and then with the power amp in bi amp configuration, was with a pair of B&W CM9's. There is no real improvement in sound quality but could hear the speakers working better a bit more control in all areas but I can't find it in myself to spend £1000 plus for a slight enhancement .I am sure I could spend that money in other areas to get a better improvement. I have just had a result from the taxman so am looking to blow some cash and this could be a consideration but hard to justify. I can not comment on how this would compare with monoblocks but I would assume you would need to look at a pre amp instead of an integrated which I guess is a slightly different game and there will be many here with experience of such set ups who can advise better than I. Good luck and have fun
