Yup, the best Sony D/Ds are strangely not mentioned much. Experience tells me, that when Sony (figuratively speaking), sat back and said: 'right, we're going make this as good as we possibly can', the results were invariably stunning. The only problem with these types of T/Ts is availablity of spare parts, should anything major go pop. That's really the main reason (SQ aside) why the Techy is so popular: they can always be fixed, if necessary!
