Waldorf Edition Tenor Recorder : [updated] Excellent manufacturing, great sound

[current] after almost 2 years with this recorder, I am excited every time I pick it up to play. The sound is so round and full bodied that even a drone note is a pleasure to listen to. I have also come to like the slight "airiness" (or chiff) it produces. Could not recommend more.

It's my first and only tenor so I might sin of lack of experience/knowledge. The higher volume of air required generates an audible "whiiizzz", especially on the G, which feels like some of the air is getting out of the labium rather than inside the internal bore. Perhaps it's the same % of air as in sopranos and altos, the difference is made by the pressure hence the noise...

I checked the tuning electronically (Garage Band feature) and to hit some notes (F/G/A) of the main register I need to blow much more than for E/D/C in the same register, again the delta being felt greater than for smaller recorders and I don't know if it applies to all tenors or just to this one.
