Guys, I have a very lack of knowledge when it comes to digital audio so please don’t shoot me in your replies. I bought an original Bifrost 2 about 4 years ago and have not really used it much to be honest. However I try it as the DAC by connecting it to the digital out on my CD player (Hagel...

I guess that I am pretty late to the party in regard to some of these tube combinations being used in the Pendant. Having always been a “music first” guy I start listening to one track and end up listening to the whole album. That’s OK but not exactly analytical if it’s tubes that you are trying...

Thanks for that. I will get on the hunt for those Funkwerk tubes. They all seem to be sold out of Eastern European countries which makes it tough to find that “reputation seller”.

I have a question for the tube gurus in this thread. My Pendant (non SE) has always had a very low level hum and nothing that I have tried has ever made an impression on it, let alone fix it. In the end I elected to listen to the music and it really has not bothered my listening experience...

Welcome aboard. You can tube roll to your heart’s content with this amp. The only thing that you should always remember is that it’s the music that matters. As Robert Hunter wrote “If you get confused listen to the music play” (Franklin’s Tower). Enjoy.

Thanks for the reply. It’s not the tubes because I have tried any number of those. Currently have tung sol in the EL84 slots and a vintage brimar 12au7 as the small tube. I have tried everything and just wondered if anyone had tried getting rid of the DC from the wall wart. I have the unit...

The hum is in the headphones not a general amp hum. Sorry if I wasn’t very clear there. It’s not ruining the music or anything like that but on high Z it’s audible when the unit is switched on. Low Z helps and that is what I have been using. It would be great to totally get rid of it.

I have a pendant (not the SE version) and have had a minor hum since the day that I first turned it on. I have tried a lot of things at Zach’s and others suggestion. Wondered if there was any possibility that it could be DC current. IFI (and others I guess) sell “DC filters”. Wondered if anyone...

My unit has the low grade hum that you will find discussed in this thread so I went with a Sylvania 5751 based on it being the tube that was the quietest. In fact that hum is not really an issue at all with that tube and I am just listening to the music now.

Thanks for your swift response. I will try to find a Sylvania 5751 at a reasonable price. In the meantime I am using either an RCA cleartop 12AU7 or Genelex Lion goldpin 12AU7. Changing out the JJ EL84s for Tungsrams has been a major improvement especially in terms of the hum issue in my unit...

I have a tube question that I have read quite aa but about on the forums but am still confused about. Can you use a 7058 tube as the output tube on the pendant?? It is a 12ax7 family tube but does not work in some preamps apparently. I tried it in the Pendant and it did work. The sound was...

I have a set of what are known as “Allen keys” (not sure if that is a US term or if it is universal) which I bought years ago for a few dollars in the local hardware store. There was a fit for all of the screws in that little kit. Realize this is a poor response and would think that you will get...

Not more than 9 o’clock when listening to any of my headphones (Aeolus, Mr.Speakers Ether flow1.1, HD650) via Hi Z with a 12ax7 or 12au7. Maybe 10 o’clock with the LCD2 on Low Z. The hum in my unit has about gone with 30 hours on it. Still a slight noise with the Aeolus but almost silent with...

I have had good experience with the Genelex Gold Lion tubes in general. I used them in my preamp where they replaced JJs in the 12ax7 positions. It was a nice improvement. Also tried one in the pendant. The sound was good but it didn’t get rid of the hum. The 12au7 does significantly reduce the...

Aeolus open back. Everyone says that the Verite/Pendant combination is the one to have. It’s a money thing for me. The Verite were over budget. Maybe some day.
