All, it might be worth pointing out that in the Wessex Dolce/Sinfonico review linked above, John Powell might be using the factory-supplied Wessex 4AY mouthpiece. This might be hampering both Dolce's and Sinfonico's expressivity, and account for their somewhat "declarative" tone, and slight brashness in Sinfonico's Holst fragment in particular.
4AY is also the mouthpiece shipped with my Wessex EP104 Festivo…. I have never been terribly fond of it, as it imparts a slight hardness to the tone, and -- for a lack of a better word -- a lack of emotionality or expressiveness. I much prefer playing Festivo with the Wick 4AL.
Thus, I am very much looking forward to John, Dave, and the other fortunate members of the Sinfonico test group letting us hear Sinfonico put through its paces and showing its musical potential using some of their preferred mouthpieces... Be these 4AL, DC3, DC4, etc...
