Hi Bo, I think used Avalon owners all over the world would be interested in the serial number of that pair might be :)
Scary cos there is no way you can access the crossovers without major hacking (literally). Scary.
I do agree with you that violins are the Avalons' trouble spot. More so with the models using the Acuton ceramic mid than the old Ascents and Eclipses.
But heck they sound good overall with a host of other material. The lean and fatiguing sound can be minimized with triodes triodes and triodes everywhere... Cables with chokes in the mystery network boxes help a bit too but at the expense of resolution.
