Installed SS3602 in LC today
Sadly, it pickup some noise, especially in the left phone

 
Is it because wifi hub nearby? Has anyone experienced this problem? how can you fix it?
 
Update: 19/11/16
Tested with HE 560 and ATH M70X
 
- The noise only happen with easy drive phone (inear, earbud, ATH M70X)
- HE 560: no noise, sound absolute beautiful

V5 fit perfectly inside Lovely Cube (remove DIP8 socket come with it)

Just got this from my vendor, setting the gain to +10dB for HD800.

 
Planning to swap the OPA2134 to something else. I've OPA627BP and LT1028ACN8 (bought them 8years ago during the AMB Lab Mini3 era!). Need to get some bass back from the HD800.

 
Sexy isn't it?

If you want get some bass, highly recommend the V5 from Burson.

Thanks mate. 
 
There is a Burson v5i, any audible difference?

I don't have OPA2134. But from the Opamp thread and sound card ZxR, you can see discrete op-amp is better IC opamp (and more expensive).
 
You can read [u][color=rgb(0, 102, 204)]newdoughboy[/color][/u] comparison for OPA2134 and V5 here:

If you go for Burson, just save it for V5 (not V5i)
 
 
Cheers

Does the signal go through the opamp when used as preamp out?

I'm not sure, but you can check yourself by remove op-amp and see if preamp mode work.

Does not work, you can separate from the volume control, with another preamplifier, to the power amp.

My LC is still living on my desk and powers my AKG K712 just fine.
 
First i used the OPAs in this order:
 
BB2134
BB2132
LM4562
 
The 4562 was quite better, than the 21XX OPAs, but after 2 years he started to make noises and the channel balance was unstable.
I recabled all wires and connectors and out of perplexity, because the problem didn't disappeare, i swapped the OPA with a OPA2604. Not bad.
Yes, it's no pricey highend OPA, but offset and sound quality of the chip are way better (sounding) in this circuit, as 2132, 2134 or LM4562.
 
A cheap upgrade i noticed, just because all other OPAs in my box where broken or junk

This sentence seem fragmented. Can you elaborate?

Will it be alright if I turn the unit on without an opamp? I'm not too technically competent.

Without op-amp I'm pretty sure headphone out will not work, but not sure preamp mode.
 
When install/replace op-amp, you must make sure:
- Type: dual
- Max voltage support: for Lovely cube should be >=15V
- Direction: half moon mark (or pin 1)
- Space

V5 has more airy (space, sparkling high) than V5i. For Lovely cube make sure you order Dual version. When install it, you might want to remove the DIP8 socket come with V5.
 

 
 
You also might try the Cable +, they use V5i inside so it will further improve bass weight.
 
BTW, if you worry about heat (if you live in hot country) you might try this

Don't need to worry too much about heat. Class A amps do tend to get quite hot. Electronic components can stand very high temperatures, that's why some laptops that overheat can be too hot to touch but still run. The amp won't be that hot though so it should be ok.
I'm running on Burson V5 too. Surprised it can fit well with no space problems. Though the improvement is subtle from my previous 4562, I can't switch back anymore.
 
What DAC are you pairing it with?

There have been a few of those V5's melting in the Gustard H10.  Some users have posted pictures on that thread.  Some even have opamp failure, not just melting.
