I don't know if there is a corolation, but my R2H MM+ and BB500 sammies seems to have a better color on 16 ohm low in firefly. VS MM+ Tbin on 16 ohm low firefly.
All three of my MM+ Tbin sammies are greenish on 16 ohm low, firefly. Including one of the MM+ Tbin which is blueish on high.
Does anyone know if lower vf makes any difference.
My TX1J is not green as you might think when you look at the pictures. At the lowest (nightlight) level it's more yellow compared to the white of the higher levels but not green at all. However I think a WA or WO will do better at the lowest level too.
