My limited understanding, having not yet built the amp, is that higher ( to a point) OPT impedance decreases distortion at the expense of power. The higher plate voltage and current may regain a little of that power, but not much and possibly at the expense of tube longevity.
But I agree, unless you need every decimal watt you can get, go for less distortion. If your system can play with 8 watts, it probably can with 6 or 7 too.
From reading the tubelab SE manual, it would seem the Greg prefers to run 5K OPT and 400V plates in his 300b version. But it may really end up being a matter of preferance. In which case, you won't know until you have heard both...Actually the tubelabe SE manual discusses this a little, so is worth a read.
