The Opamp thread

[raoultrifan]

Oh, these are great mods you've done! Perhaps you could give it a try with V5i; if so, then get a scope and check the output signal after every opamp or at least at final output plugs (bandwidth of at least 10 MHz scope). Also, an IR thermometer or a direct contact one should be OK to measure the temperature for each opamp.
 
Now, I'm just being very curious if V5i will get hot or not in your setup...

Does anyone have any experience on how much the sound changes when the V5is finally burn in?

hi
 
Burson v5i  hot in the beginning at start , but after a few hours were balanced and well...
 
in start 
 
 
 
after 1 day
 

 
Thanks

 

[raoultrifan]

Interesting! What device is that one, please?
 
I wonder how is it possible to have 76C in the first day and 37C the net day...quite strange I'd say. I'm so hoping I'll receive my V5i opamps this month to give'em a spin.

Hi
 
Yes, it was very strange. Represent SS-Audio Told me that  high temps with the v5i is not usual. Sometimes there is a bad
 
connection between components and it affects performance and  I think this is quite possible...
 
The temperature opa627 In pictures at the same location.

Hi
 
On the third day sound much better ... still good heat and low ...Great instruments and has a three-dimensional separation stage ... but I now pronounce some words in there ُُSsss  problem. It may be better to break-in more. In general, the chip is very clear and well 
 

 
opa627 Installed in another location

 
The sound was very good today. I want after burn-in install to LPF  DAC  WM8716 Wolfson  24bit 192khz 64X refresh  .

I'm quite satisfied with mine after it finally burned in.

Hey!
 
I'm planning on upgrading the Op Amp in my xDuoo XD-05.
I have it narrowed down to 2 different Op Amps:
 
MUES02
Burson v5i
 
What do you guys think is the best option between these 2? Or is there something else I should be looking at in the $50 price range?
Any help would be appreciated.

 

[WilliamLeonhart]

Either V5i or Sparkos. I prefer the V5 the most actually, but the V5i isn't far behind

 

[Lickumms]

Is the Sparkos SS3602 worth the extra money over the V5i?
 
Edit: I don't think the SS3602 would fit in the XD-05

I think the same. Too much large for xd-05

That is if you don't use opamp extender and really need to close the chasis

finally arrived the burson v5i. installed and tried.
well......i was, in the past, a set in the "high-end"guy. today, i´m more quiet and racional(my wallet sais thank you)
So, apart jokes, the meaning is that today i have an entry level system but i really like it.
when i ordered the v5i, i do not expect great things; probably a slight improvement but considering the price of the v5i, why not?????
I state that i don´t believe in technological miracles, so i say that the v5i isn´t a miracle or a giant killer but a really good product considering the Q/P realtionship.
The sound signature of my amplifier is the same but in first place the imagine is better and more focused and now i have a tight bass.
it´s a refinement of good performance of my amplifier. but more important for me is the gain.  i use an oppo pm-3, so the gain is the lower.
but, so even I could not lift much the volume. now the volume is more progressive.
really satisfied
p.s.: thanks to Charles of SS-Audio for the kindness

Was it brand new? Mine was a disaster. It was overly bassy and clarity was worse than a cassette player from the 80s, but after 40 to 50 hours of torture it finally burned in.

 

[alota]

yes. some hours of listening.if in 50 hours is better, good LOL
