Just received 6N1P from Schiit today. My first impression is exactly like what Kremer930 described before. It suits HE-6 very very well. Moving from EF5 to Lyr, the only thing i missed was the mids. Lyr with stock tubes just seemed a little bit dry. Now with the 6N1P vocal becomes a lot more intimate. The sound stage does seem to shrink just a little bit maybe due to the increasing presence of the mids.
and YES, it's super HOT. now i am wondering what i am going to do during summer. might have to put a fan next to it. hehe.....i was told there was an amp caught on fire during the NYC spring meet. def don't want that happen to my Lyr.
Kremer930, huge thanks to you. This is the reason why Head-fi is so great.
Also thank Schiit for offering these tube at such reasonable price with fantastic shipping.
