  Hi, I have one of these babies and am mostly loving the sound quality. I am mostly converting CDs to WAV using Foobar but I am still getting problems after at least 30 to 40 hours of use - I get a regular faint click noise, like a scratch on a record, after playing a few minutes. At first it continued for about 15 minutes then went away but now it goes on for at least my commute to work - an hour. 
I have read they need running in and issues like this go away, how long is this running in period? 
Out of interest can anyone explain why they need to be 'run in' and what this actually does? I don't really understand why modern electronic components would need running in but that may be my ignorance!
 
Cheers

If your walnut does not have at least 20-30 hours on it then i would keep waiting.
 
I've had something like 5 Walnuts (2 of them i gave away) and on each of them i got an occasional pop or click like you describe until teh 20-30 hour mark. then it goes away completely.
 
Some of them i just let it play into some headphones for two full battery charges, by that point its about 40ish hours on it, and they all sound prfect...
 
Honestly i attribute the pops and clicks and such to the electronic components settling. The walnut is assembled from fresh parts and only tested very quickly, so it's not like a more expensive player which might have enough testing at the factory pre-shipping to remove these glitches of very fresh parts?

They are both great, but I prefer the Fairchild NE5532N. It sounds fuller and more open, with much better sub bass.

Compared to original 5532?

Yes, and the JRC NE5532 and the Signetics NE5532.

Are jrc 5532 and fairchild 5532 pretty similar?

Not to my ears. The Fairchild is more dynamic better sub lows and texture.

Dang it i'll get one. argh!

You won't regret it.  I had actually ordered signetics from the link I posted above, but they sent me the Fairchild ones instead.  I wasn't too happy until I gave them a shot.  Vapman, make sure you ask for the Fairchild if you order from the link I posted.

I forget it anyone has tried the Philips  stamped 5532 yet?

Will do

It's stupid how good the walnut (jrc4558d opamp) + either ultrasone hfi-680's or kef m500's sound. Listening to this Riverside song as I epiphanize this:

Sounds like an empty battery to me

hi, no unit is new and fully charged. Does it whatever the charge, I get good battery life!

 

[flamesofarctica]

How does something with such massive sound manage this battery life, it's insane :-D

Edit - didn't read topics above, coincidence it seems to follow on!

Cheers mate I'm sure you are correct! I'll keep running in! I actually have 2 units but the second one only has a few hours on it at the mo.

I tried some opamps that I have had sitting around waiting for me to try them, which was OPA1602 and Signetics 5532 (year 1984). Both quite nice, didn't blow my socks off though. The Signetics is much less detailed than the JRC version, but I kinda like it's tonality better, the JRC had more bass though. I really need to get around to soldering up the ADA4627's.

I can't use the walnut as standalone now since it won't turn on and still works as amp though. Could the power cap causes the problem?
