Well everybody I have ended up with the 331, it just had a touch more bass extension and control that the 27.5, tonally slightly richer, however I would still recommend the 27.5 to anyone.
P.S I have just slotted a Nagra PLP preamp into my system which allows the Wadia 860x to run on full gain with simply astounding results. I believe that this quality of preamp more readily allows you to hear the overall gains the 331 has over the 27.5.
