The power supply was a huge improvement on my 2009 Mini. I would say a 25-30% improvement. Steve at Empirical says a stock 2009 mini sounds better than a stock 2011 Mini. So this means my set up is perhaps 30 plus percent better than a 2011 Mini without an upgraded power supply.
Oh well. Must try both to really know!
