Anyone regretting Pontus 2 firmware upgrade

No regrets for the upgrade and no desire to roll it back. I’m hearing more detail, a slightly wider soundstage and improved bass. I have mine set to NOS mode as I did before the upgrade. 

Like the other posters, I'm experiencing notably greater clarity (but not harshness/brightness) and better soundstage. Bass sounds maybe a bit tighter, not much change there on my system. Overall, a very positive improvement, imho. However, if you really love the sound you're currently getting, you should probably skip the upgrade. If it ain't broke....

I'm holding off a bit.  A few weeks ago I opened it up to get the pic of that chip and there is "stuff" on it.  Whitish smudge of something, almost covering the number.  Did not expect that on a piece of audio equipment at this level.  Sent both Vinshine and Denafrips an email(w/pic).  The response was disappointing. Very nonchalant about it.  "Just some leftover flux or such during fabrication.  Do not worry.  Clean it off."  Huh!?  I don't want to touch it and asked to please send me a replacement DSP.  No go.  They ignored my request and just sent me the download instructions w/order #.

What should I think?  Am I making to much a deal about it?

Iracosse:  I would take a small swab and a bit of alcohol (or possible household cleaner) and see if you can get the whitish smudge off the chip. Don't use so much that it drips or runs off the chip! If this does not work, post a GOOD closeup photo to this thread, so we can get a better idea of what it is like.

Can this DSP upgrade be applied to original Pontus?
