I have after many years upgraded from my trusty A&R Cambridge C200/SA200 to an FMJA22. It was worth it, almost everything is better although I suspect that the SA200 might just have a bit more base control. This got me thinking why not bi-amp using the integrated amp to do the treble and midrange (with the vast improvement in depth and clarity that the FMJ A22 has) and use my old SA200 to do the bass. The only problem with this idea is that the two amps have differing gains. The SA200 has a gain of 29db and the FMJ A22 has a gain of 31 db. So any ideas?
