@ calvinj, Hi, I have no idea why yull1375 does not talk no more, I hope I my cables was not imtimadating to him!, He is a really nice guy, I enjoy talking to him, I would like to see him come back!, calvin, you are a trip!, Please understand what I am saying!, your player takes 450 hours of break-in!, your new tubes will benefit your sound extensivly!, However, It will never fix the forward sound!, I really hope I get supprised that the Dr tubes fixed the forward sound!, I really do not believe that is possible!,, Also, please understand that all tubes need atleast 100 hours or more of break-in time when you tube roll!, I do wish you luck!, I would like for you to tell me all your findings, you are not a bad guy, just inexsperienced, no problem!, there is no way you will know your sound untill you achieve the proper break-in time!, cheers.
