I have the Rega IO driving QA 3030i Standmounts. Listen mostly to Tidal off my MacBook via a Topping E30 DAC. To my relatively inexperienced ears the sound is exactly what I wanted. I used to run NAD for many years into Tannoy Mercury floorstanders and then swapped to a Sony surround sound amp. The IO / QA combo is very reminiscent of the NAD setup, very neutral and engaging with all types of music. I have recently wired in my old Tannoy FX 5.1 sub running at barely audible volume and it just lifts the whole bottom and mid range to another level. You wont go wrong with an IO, and you will be supporting British industry.
