Audio research ls3 or audio Research sp9 .Any difference in sound .Need a phono stage,have a chance to trade with a friend ls3 for the sp9 ,the sp9 is mint really mint new golden lion 6922s one in line stage and one in phono.What do you think.
Get the SP9 and replace those modern tubes with some vintage 6DJ8's/6922's. Sylvania, Amperex, Philips ... Much better sonically than present day production!
SP9 is considered a classic ARC preamp. Do the trade! I have an even older SP6 that I like better than any of the overpriced new ARC preamps! All of these from the SP2 to the SP15 will become desirable to collectors!
