The Holo May is highly regarded and should pair well with the RS2T. I can’t think of a reason why this would not be the case.
The Fidelizer Nikola II is overbuilt in my opinion. I’ve had mine on 24/7 since purchased in January 2022. Not even warm to the touch and it’s absolutely silent. So, an over spec’s power transformer and very good quality parts. I’m very happy with it.
