@jetter I made the upgrade back in March, I think it was. Definitely a good few months ago at any rate, so I feel it is fully settled in now.
The cost plus import costs/VAT for the board and PSU was a little over £200 - definitely worth the outlay for me. It makes the Node a different proposition compared to an un-modded unit.
There was/is definitely more clarity, and greater opening up of tracks. To my mind, the upgrade takes the Node to what it should be. I think Bluesound had a budget/price level to stick to and the in-built SMPS is the result.
