hi all had on loan a counterpoint sa 3.1 valve preamp which as far as i can gather were handbuilt in california and was possibly cica 1990 or thereabouts, had this linked to parasound power quite a nice sound , but dealer had a customer who was desperate to purchase this and have it shipped back to the usa for refurbe so returned pre to dealer, just wondered if anyone had heard this or simular pre as i could find no reviews on this particular pre nor find its original cost. thank you
