Sabocat - I have a 2A3 SET and also recently a Manley Stingray. The Stingray uses 8 EL84 tubes for outputs. The Lores sound great on the SET but even better with the Stingray. I'm in a 12'x13' room, so the SET can play loud enough. The PPP adds a lot more weight and thump.
I doubt you'll feel you have a mismatch with your EL34 amp.
