I finally found one of my grail DACs. The price is good, not great (it's for sale by a dealer). Question: being from the 1990s, is it good to listen to as-is or should it be re-capped?
By the way, I've posted the next NOS listening experiment in my investigation thread, see link below. You are invited to join the fun. 🙂
