Awesome, let us know how the Schiit is performing. I don't mind their product segmentation, they seem to put in some thought into the use case for their equipment. I don't think a headphone amp is needed for a preamp that is predominantly aimed at stereo listening. One can always use the preamp outputs to route those to a dedicated headphone amp like the Jotty which would be much better in any event.

They are very active on the headfi forum.

You should be able to run balanced headphones off the XLR outputs.

Many are talking of this as well as using balanced out of their DACs into the Freya and then unbalanced into the Jotty

That Saga looks pretty sweet for those who don't need balanced.

What are you hoping to achieve with the change? Brighter, more laid back ?

If more laid back, have a look at the Sylvania 6SN7GTB. It's often described as a more relaxed sound than the stock ones.

Spares is 1st though, bit of a disorder when having tube gear.

Sylvania 6SN7GTB from what I read is a popular choice.

Have already spoken to Charles about his thoughts.

Cant give you any advice about tube brands i am afraid although apparently the chinese currently manufacture a fancy 6SN7. I wouldn't worry about spares though; 6SN7s are current manufacture plus preamp tubes tend to last forever.

Here is an interesting list of 6SN7 substitutes : http://www.vacuumtubes.com/6sn7.html

Check out the various datasheets to be sure .

@fredeb

Thanks, might have glanced over it already.

The 5962 types are going to be scarce and expensive.
There is a Russian equivalent called the 1578 which is also scarce and very expensive.

A Electro-harmonix Gold 6SN7-EH seemed like a good expensive current production alternate and maybe Tungsol, although also in limited supply.

Reliability could be a concern if NOS tubes are sources from sketchy EBAY listings promising matched, tested and new in wording, only to have it fail or not even matching the test data.

As I preferably need 4 of the same brand although 2 different pairs would work. Charles has found a quartet of Italian 6SN7-GT's that he will be checking.

I can only repeat that the so-called "sound" of a valve is simply due to a spread in characteristics, unfortunately too prevalent these days.

The 'sound' of a particular amplifier has 90% to do with the circuitry, not the used valve. Very often (mostly?) comparative tests have been performed using only one or two valves of a brand; had the tester taken the trouble to test the characterisitcs of tested valves he was likely to have found differences in operating ponts related to the particular valve's characteritics, not the brands. (In those few hearing tests that have included measurements, different 'audible sensations' were always found to relate to valve - not brand - differences.)

I have used a number of 6SN7s over the years without trouble, but I have never bothered to compare between brands.  Up-to-standard valves: predictable results.

found a quite informative page about 6SN7 tubes on head-fi :

Indeed a very informative reference.

Where did the writer get all that information? Did he use all those brands himself? Still - and going back to my previous post, it is to be appreciated that the over-simplified "sound of" topic is not attached to any particular brand.

@Ampdog,

I think it is a collaborative effort?
