They mention on the description of the AUNE T1 that the new version. Which is the one I got has an upgraded tube. the 6922EH.
To me this actually sounds better than the one I bought for it.. You guys that have this tube should try it..The sound is not as bright as I remember it and in fact very much perfect. So I don't think a tube replacement is necessary for the guys that are going to get this unit. There was a few tracks I tested out where there was a bit of sibilance happening and that caught me off guard last night as great as it sounded. Testing out same tracks now. The sound is somehow cleaner using the stock tube and I don't think it is fully burned in yet either so I will let this play all day to get a good idea of the how it sounds with the tube but so far I like the stock tube better.
Will give it a try. Of course, I figured the aftermarket tube would be best, but dumb of me not to try the supplied tube. Only bad thing is getting those plastic protectors off is a pain, I broke one already, so need to be careful. I don't even think I need them, since it's on my desktop. But going to try and be careful this time. They gave us two sets, which is good.
Update: Well, wow, you are right. No need for the aftermarket tube, it seems. I am nowhere good enough to say the other tube was superior and with Painter Song (Norah Jones, Come Away with Me, 24/96), the detail and sound is just as if not more impressive. Now this is with first listen. The other tube had 30-40 hours on it already. So looking forward to letting this amp run in a bit. But honestly, no need for the extra expense. I just jumped the gun.
With more listening, not sure it's all that much different, but it could be the lack of burn in time with the new tube. I put on some of my most sibilant tracks and they sound a bit harsh with the stock tube. With the Grados, I am using a wee bit of bass EQ (I use JRiver Media Center as my player). Also using Wasapi + Event Style as the output setting. Need to do more burning in and listening. I think the stock tube is fine, but not sure if the aftermarket tube is better or not. Good to have two in case.
