I've had my PL HP for 4 years.
ML stats have been on my radar among many others.
I found them to sound fantastic with the PL.
Using sealed floorstanders/sub, and just looking for something different.
IMO, a subjective decision that only your ears can decide.
You won't know until any speaker is in your room.
This review mentions tube/SS performance with the Summit X

If more power is needed, you could drop KT120 or 150's to replace the EL34's. Other than visceral DEEP bass, I didn't hear anything lacking with the EL34's. Subs would take care of this.
This is just my personal taste, someone else may find it okay without a sub.
