I own a pair of BHK 300 mono block amplifiers. Purchased from a nice fellow a month or so ago. I hooked them up and got them working and sounding great. I also purchased a new matched set of gold lion 6922 tubes and replaced the original tubes in hopes that the sound would be better. Well, it sounded pretty harsh but I decided to leave them in hoping that they’d mellow out. That’s been a couple weeks now. I played some music on Friday and it sounded really bad so I put the original tubes back in and now they sound great.
My question is: Should I have left them in longer and allow them to mellow or do you think I got a bad set of tubes. I hate to think that when the originals go bad that I have go rely on them for the best sound possible. Thoughts? Should I just purchase tubes from PS Audio or find some alternatives?
