Default What would a larger OPT get me?

I'm debating upgrading my James OPT from the 6113 (10 watts) to the 6133 (30 watts). My 300B SET is run conservatively at 5 wpc (370V / 65mA). I wouldn't change those settings. I'm curious: what benefits if any would I get from going to a larger OPT aside from bass?

It would be harder to over saturate the core. I was running some smallish 8k opts on a 6v6pp and could easily over saturate them. I replaced them with 30w transcendars and have had no issues since.

Yes, you will have better bass.
