If you are looking for warm, I've found the Oyaide SWO-GX to be a sweeter sounding outlet. That said, I do agree with Lak that 50 hours burn in is not long enough.
However, considering you are using a Nordost cables and power cord, as well as Arcam electronics, I have no doubt that you are hearing sound that is thin sounding. I find it easier to change cords to suit my tastes than to change outlets, but I do realize that everyone is different. So try the Oyaide SWO-GX.
