It's probably worth asking why do you want (a fairly powerful) amplifier for iems?

In my experience probably not the best. My unit may be atypical but I have a hum that is audible on low gain and no music playing with my Grado SR60s on every tube I've tried. It's not volume dependent, but I'd say it's still usable with many of them. With HD580s I don't notice it at all on low gain with most tubes. I would think most iems are more sensitive than the Grados and sitting right in your ear canals, so probably not the best for a tube or hybrid amp in general.

I wouldn't say in general.

 

Campfire Audio makes very good hybrid amps for IEM's and I have heard the Schiit Valhalla 2 does a very good job with IEM's.

 

The point is to gain the advantages that come from tubes which solid states don't provide.

 

If anyone has had direct experience with IEM's with their Valhalla's please let me know cuz I'm not going to base my decision of conjectures.

If you want to know for sure, just email info@schiit.com.  

 

With the IEMs I have, the hum is louder than the Grados.

 

The specs I see on Campfire's page shows their IEMs range from 1/3 to 1/2 the imepedance and from a sensitivity point they would be 4-8 times as loud with the same input as compared to the Grados.   So, in my experience it would not be a good fit for IEMs.

 

The Valhalla is a different amp than the Vali (it's a OTL tube amp) and for me it's much quieter with all my headphones.  Since Campfire IEMs are very sensitive, you probably wouldn't have any problems getting adequate volume.  The bigger problem would be output impedance which for the Valhalla is 3.5ohms in low gain.  If you use the standard 8 to 1 ratio, you'd want a IEM with an impedance of about 28 ohms.  Some of the Campfire IEMs are in that ballpark, so it might sound OK.

  • Cheap ones in a plastic enclosure.  You can get them for $2-$3 on ebay/amazon or from tubedepot.com.  
  • More expensive ones in a nice enclosure that are silicone weighted to reduce vibration.  These are ~$30 from TubeMonger.com

Like many other things you will probably find different opinions, but if you aren't having any issues with vibration I would save your money and get the cheap ones.

This thread has a lot of info if you read through it, and there is a Vali 2 tube roling thread with lots of commentary on different tubes.  Basically you have a huge variety to choose from and you only need one tube which is why the Vali is great for tube rolling. With no adapters you can run: 6922, 6DJ8, 7DJ8, 6N1P, 6H23P.  With a 6N3 adapter you can run: 5670, W396, 2C51, 6N3P.  With other adapters (and a socket saver) you can run: 6SN7, 6F8G.  I'm probably missing one or two variants.  

How different tubes sound seems to be very individual.  I personally think the GE5670 tubes with an adpater are cheap, sound good, and one of the quietest tubes in my Vali 2.  Without an adapter I liked a JAN Phillips 6922 I had laying around from a different amp (and I didn't love that tube in that other amp).

I agree completely.

Considering you are all expert about the Vali 2, what does it makes it better than LD 1 Little Dot MK2? It's a very honest question, cause I got the Vali 2 too but it's my first tube amp so I can't compare it with anything else
