Asus Essence ST/STX (RCA line out) with an external amplifier

Hello Head-fiers

 

Some context:

Headphones -- Sennheiser HD 598

DAC -- Asus Essence ST

 

So my I'm running my Essence ST and I love the sound that comes out of the RCA line out.  However, I'm not as impressed with the headphone amplifier that is included in the Essence.

 

I was wondering if anyone out there is using RCA line out with the Essence ST or STX while using an external headphone amplifier

for example, like a little dot I+ or some other alternatives.

 

I'm curious because I'm looking to purchase the little dot I+ but I'm wondering if the soundstage and clarity will improve as compared to the Essence's headphone amplifier.

 

Any experiences or thoughts about this would be appreciated.  Thanks.

I use Essence ST to an amplifier. I honestly don't think the difference is that huge, but that's mainly because the headphones I use are not that hard to drive. The bass is more controlled, highs are smoother and it's a bit more detailed overall. The difference would be bigger with headphones that are harder to drive.

You could try switching the opamp in the card as well if you haven't already.

I use the Xonar Essence STX's line out with my Little Dot Mark III and Sennheiser HD650 cans. I've briefly tried using the STX's amp (I had my Little Dot before I got the card) and wasn't impressed. It definitely didn't sound better in any regard compared to the Little Dot.
