Think the Mid monoblocks I currently own are the ones from Sid. I am driving Cadence avitas with them and it just sounds beautiful. Haven't heard the VA 1 pairing with Avitas so this is the best so far for meNice to hear they work well with modern speakers. But I would still not use it with modern speakers. I think they work best with high efficiency speakers and ones using paper drivers. Their resolution and transparency will go a notch up. I feel it’s too simple a design to pair it with complex crossovers. It also has a very low damping factor to control modern woofers.
