I swapped out the Tuba for my Woo WA3 OTL yesterday and am a bit torn on the sonics with the Bokeh. The Woo pairs wonderfully with all my 300ohm ZMFs but with the Bokeh the dampening factor sounds a bit too low. The overall tonality is good but the drivers sound slower and less controlled. Resolution is softer, and bass has lost some impact, and become more boomy. This is in comparison to the Tuba via the low z output. The Tuba's lower output impedance IMO gives are more synergistic dampening factor with the Bokeh. The Woo/Bokeh combo is sloppy sounding in comparison. Let me stress this is in direct comparison, not in general. I do like how the Bokeh sounds on the Woo overall, but I like it more on the Tuba. I'll give it more time to adjust mentally, but I can't help but think the Bokeh is at it's best with moderately high output impedance staying under 50ohm OI. The Bokeh/Tuba low z combo is really good IMO, being both euphonic like a good tube amp is, and also very tight and technically capable like a solid state amp. That makes sense given the Tuba is OTC not OTL. But on high z on the Tuba things start to get a bit loose sounding, more like the Woo, which makes me think the Bokeh is reacting more to dampening factor/OI vs transformer/non-transformer.
