Thanks for all your input.
Bit of an update, one of the reasons my son bought the Leak 230 was because of its flexibility, he also has a Naim Nait 2 which I bought for him years ago, so in a moment of wisdom as it turns out he decided to try the Naim instead of the Leak.
Low and behold his words to me were, whilst the Leak is better in terms of the hifi nicety's it wasn't as musical or enjoyable to listen to as the Naim, so the Leak is being returned and he has just won an eBay auction for a Bluesound Node N130 with upgraded power supply.
