540 TX audio
I do not know where your drive is set, but if the drive is set too

Agree that even if the transaction is only on the surface, a transfer of assets (of course it depends which ones) there may be valid financial reasons for choosing it, but in my experience, in general,it just doesn?t ring the right bell. Anyway, let?s hope that the ?new? owners can and will invest in new products because in my book their product line is quickly falling behind the curve.
