Playing around with the RMAA, I've noticed another "strange" thing: in the Frequency Response multitone test the left channel is about .2dB higher than the right one! Modifying the balance from 100-100 to 98-100 (L/R) in the windows audio panel does improve the things, lowering the gap to .05dB.
Here are the figures in the two configurations.
Does someone has noticed this on his Essence as well?
Just when I thought I had it narrowed down to a problem with the STX...
Now I'm thinking it's my PSU that's the problem. I tried plugging another power connector (sata style with converter) into the STX and the levels were much better in RMAA. They only bobbed up and down maybe one or two bars. RMAA now says there's a problem with crosstalk but advises that it could be due to the cable.
My PSU is a 330W Seasonic S12 II. I figured that's plenty of power for an nVidia 9400 / Intel E7300 C2D system. But I'm sure it's a single 12V rail design. Now I'm wondering if there's any sense in getting a much larger PSU and putting the STX on it's own rail.
Well this isn't going to be too popular but after comparing the STX with my iphone 3gs, I have to say, I like the iphone.. a fair bit. And the iphone is considered bright but I have to say, its darker then the STX. The bass with stock opamps through the HP out is really dissapointing me now. It hasn't before as I hadn't compared the two but now that I have, I'm finding it lacking.
This is with the JH|13 Pro headphones.
I'll soon be redoing my water loop (finally) and will have easy access to the STX for op-amp swapping... I'll be soldering up the HA's and putting them in the I/V .. that should add the bass from what I've read
I'm thinking its just bad synergy with the JH-13's that are making them sound brighter then I'd like with the STX HP out
Anyone else feel like the stock STX HP out is on the bright side? Perhaps heavily so?
