Hi Everyone. I've been skimming through various threads and noticed that there aren't any threads specifically discussing preferences between the Sovtek 6C45 and upgraded Harmonix 6C45 tubes. I've only had my WA7 (paired with my HD800s) for a week now and think I am going to stick with the Sovtek tubes. I feel like the Harmonix is a little easier on the ears, however, I feel like I lost a bit of the detail that I am enjoying with the WA7. I'm a little surprised this is the case as I expected to enjoy the upgraded tubes more.
I'm still pretty new to the head-fi scene so maybe my analysis doesn't make sense :-), but would love to hear what tubes you guys are sticking with for your headphones and why.
