Well, OTL's are inherently high output impedance so unless I am wrong, that is wishing for quite a lot..
But the Leben CS300 is really nice with low impedance stuff. It has output transformers, though, but I find it generally better balanced than the WA22, with more bass quantity (no loose bass - albeit not super SS tight).
So - if you sell the WA22 and your big rectifiers, you can rebuy a WA2 (maybe you can get a hot rodded one) in a couple of months of NOT buying tubes , you might have enough money to aquire a nicely used CS300 ,) So then you have the WA2, GS-X and Leben - which is probalby gonna suit you extremely well. Or you can just get the WA5 - but then - it's risky business - you might not like it. Maybe it is even more WA22 than WA22 :D
