Dang, I guess I'll have to add a pair of A2900's to my list. The 6201 Valvo Hamburg gold pins are quite versatile. Nice middle ground between the Telefunken ECC81 angled getter and 6201 Mitcham, If the pinched waist sound like the regular, only better, I'm in for a treat. Lol. I haven't found an ECC81 style that reproduce the timbre of a violin correctly, however, the ECC82 Valvo angled getter are beautiful at this.
