I have Koetsu Urushi (original wood version, but rebuilt by Sugano Jr). You hear Koetsu's magic mid range and excel in strings.But I don't think Urushi is perfect, rather even in all spectrum, at least not in punch, impact and dynamics. I use it in the latest VPI TNT turntable, in certain way this TT compensate some dynamics. Vocal and strings are all about Koetsu.
