I have T1s on the ST on highest gain. At about 50% power they are basically too loud to listen to comfortably. I think you'll have enough power. A lot of people who have been having issues with sound power have found they have a software setting somewhere that's limiting the volume.

What is the T1?  What impedance are they?
 
From what I've seen about people recommending the 250 ohm version with the STX isn't due to volume but rather sound quality and bass response.  Not really sure what to believe though.

Beyerdynamic T1. 600ohm, very power hungry. there's a thread somewhere talking about the differences between the 250ohm and 600ohm versions in terms of sound, but iirc, there's not too much of a difference overall. Could you find the post where someone said the 600ohm didn't go very well? Sometimes you have to take opinions with a grain of salt, based on the user's experience.

I'm not sure where exactly I saw it (my head hurts now, I've been furiously googling about this very issue for the past 2 hours )
 
They basically said it wouldn't drive the 600 ohm version to its full potential and a separate more powerful amp will make it perform better.  In your opinion would it be better for me to go with the 600 or 250 ohm version for the STX?

There is zombiex's comments on the 600 vs 250. I don't know how anyone could say the STX doesn't have the power for 600ohms, unless they were doing something wrong, or not adjusting the gain at all. The STX is honestly more powerful than most headphone amplifiers available!

Hopefully that'll aid you on your purchase.

Hi guys

I have an Essence STX and Tesla T1 also. Tracks with a lot of bass are causing problems... It really sounds like a more powerfull amp will help. I'm using foobar2000/WASAPI, foobar volume is set to 100%, using ASUS Tool for volume (or system volume, is the same). What am i doing wrong?

What did you set the gain to?

Thanks, I did see that thread (spent the whole afternoon googling about my dilemma).
 
I think I might go with the 600 ohm ones.

Get the 250-Ohm version, I'm of the opinion that usually the 600-Ohm (of anything) is usually only a little bit better then the 250-Ohm version.
Besides, if you have never listened to the 600-Ohm version, you would never know what your missing out on anyway
 
Currently listening to Taylor Swift-We are never ever getting back together, with my DT880 600-Ohm plugged into my Essence STX (3 X AD797BR).
Volume at 60% is plenty loud. Volume at 50% is a very comfortable volume.

If the 600 Ohm version is supposed to be a bit better and the STX can get them to good volumes why do you suggest that I go for the 250 Ohm version?

PurpleAngel, didn't you have 3x LME49990 at some point in time?  Mind telling me AD797BR and LME49990 souind like, especially bass wise?  I've seen one person comment that AD797BR/THS4032/LME49990 are top choices for "neutral"...quite not sure how neutral is supposed to be.

I guess the 250-Ohm version is the "safe" recommendation.
Usually the (big) price difference, between the 250-Ohm to 600-Ohm headphones is not worth it to some people.
I like to think buy the 250-Ohm and a cheaper sound card and spend the extra cash towards a better amp.
If money is no option, then get the 600-Ohm, if your willing to pay a for a little bit better.
As your looking at the DT990, it might be a little more worth it, as most people will notice the difference for the DT990.
 
Maybe get the Essence STX, but hold out on buying the DT990 600-Ohm until you finding a used one for a good price.

I bought 10 LME49990 chips and the dual SOIC to DIP-8 adapters and even the soldering iron.
I realized after seeing how small the LME49990 op-amps are, that my eye site is not good enough for soldering them.
So I ended up buying pre-soldered ADA797BRs from China.

you might been able to get some one to do it for you, That what I usually do when I was rolling op-amps. Because I knew if i tried to do something like that with my shakey hands. I prolly mess it up.

If you can get the 600 Ω version at a decent price, it is worth giving a try with the Xonar STX. The card can output nearly 7 Volts (RMS, at the highest gain setting) into that impedance with very little distortion, and that should be enough for the majority of people. For comparison, many use 250 Ω DTxx0 and even AKG K70x/Q701 headphones from the FiiO E11, and think that combination is fine, while the STX powers the DT990-600Ω better.
 
Of course, choosing 250 Ω instead has the obvious advantage that it is reasonably usable from many other devices with lower voltage output than that of the Xonar STX.
