i was abit wrong.. have my left channel on 50% and right on 100. its weird tho.. hope caps will fix it or just forget about the stx 2 and move onto something better. because this is starting to be expensive

I know the feeling after going through 1 STX 2 and 7 Burson V5-D's and 1 V5i-D. That's when I stopped experimenting. Roughly $500 in amps alone burned up not to mention the STX 2. Until I can find answers why they burned up.

did all this happen in the same pc ?  in the same slot ?
 
there might be some regulation issue with the power supply - what are you using, and how old is the psu ?
 
is it "fed" via a molex off the power supply, or is there an intermediate adapter ?
 
fwiw i run two separate machines with the xonar hdav 1.3, and both have been flawless with burson v5i in the buffer slots - both have more than marginal power supply for the components (corsair hx650 and antec earthwatts 500 in a gaming i5 and basic i3 rig respectively)
 
could that possibly be an issue for your set up ?

It's been tried in multiple slots on two separate STX 2's. It uses a molex off of a HX1000i. I'm using a Maximus Formula VII. Edit: This HX1000i is less than a year old.

ah... too much power

That's just the thing. No one has been able to tell me what's causing this. What I do not understand is why the normal amps do not have issues. However, when I use the V5's they get hot; almost hot enough to burn my hands. However, the same issue is persisting on the 2nd STX 2. After the last two V5's and the V5i blew up I stopped trying altogether.

  Bursons are better than Muses. However, I've yet to find out what caused my STX 2 and it's V5-D's to burn up. So for now I cannot say if it's safe to use them in one since I've burned up one STX 2 and I've burned up amps in two different STX 2.
 
Now from the Muses I use 2 8820 (Muse 02,) and 1 8920 (Muse 01.) I've found that it sounds better than 2 8920 and 1 8820.

Edit: As I said I've tried 3 V5-D's, 2 V5-D's and 1 V5i-D. Both destroy setups completely destroyed anything I have ever listened to in terms of amps. However as was stated they quickly got hot and burned up in two separate STX 2's. Yet, I see plenty of other people doing it without problems. So I have yet to find the cause.

 
yeah I read about the bursons causing some channels to have problems over time from multiple people (maybe it is a voltage issue?)
 
I still have my old stx1 maybe il try bursons on that (since it wont be a big deal if it burns up)
 
for stx2
 
I guess I will try the 2-1 setup both ways for the muses and see which one sounds better.
 
Anyone else have suggestions on this?
 
 
Also, the 2 amps in the IV stage are the ones that affect headphones right so if im using my DT 880s there would be no diference between putting 2 muse02s and 1 muse01 versus all 3 muse02's right? I think I read somewhere it only uses the buffer stage for the speakers RCA?

different motherboard and i am using a "adapter" to get the cable long enough. maybe that one is bad. i dont know. im using a xfx 1250 pro powersupply.

It definitely sounds like a Burson / STX2 issue , as others have been experiencing similar problems with the combo , but not with the original STX . It would be nice if someone who had a similar problem would chip in here .

btw I just saw that muses03 are coming out soon (december) supposedly its going to be better than 01/02

NJR's press release re new flagship op amp Muses03, dated Oct 11, 2016:  http://www.njr.com/products/press2016/MUSES03.html

Damn, I hate reading about V5 / V5i defects and/or incompatibilities.  Last week I ordered Burson op amps for my new STX II because its stock Muses 8820 / 8920 are so lousy that after one week I switched back to my Dell XPS' onboard Realtek ALC3861 audio.  I'll not go back to STX II unless Burson V5 / V5i (ordered both) significantly improve its SQ.

 

[th2pun1sh3r]

what kind of headphones are you using jay? I definitely think the stx2 could use some tweaks with op amps but its not "that bad" is it?

 

[Jay Callen]

th2pun1sh3r,
 
Since installing the STX II last week, Adam Audio F5 stand-mounted powered studio monitors have been my primary source for near-field critical listening, not headphones. After the Burson op amps (waiting for arrival) are installed and compared, then I’ll learn a lot more about the SQ of swappable op amps vs. sound card per se.

 

[th2pun1sh3r]

ahh yeah I have a pair of logitech speakers w/ sub but I think the asus guys said you need to swap the buffer to make the speakers sound good. Headphones are way better though.
 
I am hoping muse01/02 combo will improve speakers

 

[Jay Callen]

  ...I am hoping muse01/02 combo will improve speakers

Well, for that kind of money plus a bit of price negotiation, one could buy discrete or hybrid “audiophile designer” op amps which virtually every Head-Fi reviewer says beat the monolithic IC Muses8820/8920/01/02 hands down.  And that's why I considered Sparkos SS3602, Burson V5 / V5i, and ordered the latter.
