Somebody needs to make a FAQ or sticky thread

[mwahahaha]

OK well the 47920's are now in - bit of a struggle straightening the legs to get the little buggers in the sockets but I got there eventually!

One thing - how hot are they meant to get? After a couple of minutes the one on the right if you're looking at the DAC from the front was very hot to touch after I unplugged the DAC just to check they were both securely seated.

No idea. I just put the lid back on. Nothing on fire as of yet. How are you finding the sound?

[mwahahaha]

A little leaner as you found although I think that is because there's more going on at the top end which is good. A more spacious sound than the original. Not a "night and day" change but I didn't expect that at all - just a refinement of what was there already.

Overall - a very happy camper!

I found that they took a good few days to settle down. I don't know why. Maybe it was just me getting use to them, but they certainly get more refined. And the bass is LOW

I've had my 47920's installed for about an hour now with the DAC playing through my amp and my headphones to run both opamps in and they are only slightly warm to the touch. Perhaps this is something to do with the impedance of your headphones if they're quite high or low or something? I don't know much about driving headphones as I prefer not to use them.

On the subject of the 47920's, I'm liking the sound so far. I've not noticed a massive difference yet but I think that's because my speakers aren't good enough to make a critical comparison. I should be getting some new ones soon though.

I have noticed a little more detail overall and more punch to the bass.

with the LM4562NA I found an obvious and immediate difference.

As in different sound signature kind of difference.

As time went on it became better and better (and more different from the original sound)


Agree that a sticky about best Op Amp to use, various mods would be good. Perhaps even a Poll or two?

Aye I went from the 4562s to the 47920s so the night and day wasn't there as going from the 4562s from the standards. I'm looking forward to seeing how the 4032s sound in comparison though.
