@gibalok did you ever try to bi-amp with your VX-5 Twenty? I have the same amplifier powering my Legacy Focus SEs. Although it sounds great, I want to experiment with passive bi-amping the bass drivers with a Class D amp. I do have on order a 7-channel HT amplifier from D-Sonic. It also has 26dB max gain like the Ayre. It will be 800w/channel compared to Ayre's 350w/channel, so it's a bit over the 2:1 ratio. But I'll try it when the D-sonic arrives and if I don't like it for the better, then nothing gained, nothing lost. It was bought for my center, surrounds and atmos speakers anyway.
