Strange Loud Popping Sounds

Any updates?

The Delos and the JC3 (particularly the original JC3-gain was reduced in the JC3+) are not a good match. See:

Too much output and too much gain. It's a bad combination. 

Does the phono section ever do this when nothing is playing?

I couldn't tell you for sure but the signal path for digital should be the same after the preamp input jacks, so i would bet on the phonopre.  The other reason I think this is a discharge at the phonopre level would be amplified extensively especially if you are using MC carts, thus the tremendous volume even at relative mild listening levels.  I would swap in another phonopre if you can.  good luck.

Yes!  Very startling and lowering the volume on the amp does not reduce the sound of them.

I did not experience this when playing digital sources, only analog.  

Are you sayiong a bad capacitor in the amp or the phono preamp?  I just sent the amp in for repair as it completely lost all sound out put.  Could it be capacitor related I wonder?

I guess I will know soon.

Thanks 

Sounds like a bad capacitor, had the same thing in my manley chinnook.  Do the pops startle you and cause extensive woofer excursion?

OK, so after a while I have finally gotten around to trying different loading options to see if that was the problem.  My cartridge is a low output MC Lyra Delos and with my other amp I was running it on the 100 ohm setting with great results.  With the Primare amp I switched it to the 47 ohm setting to see if the pops would go away.  I listened to 3-4 album sides last night with no pops, but after that the pops returned just as loud as before.  
I then tried the MM setting on the JC3.  While the pops seemed to be gone the sound quality was not good, so I quickly eliminated that setting as an option.  
I'm really stumped.  I love the sound of the Primare amp but my primary source is analog so if I can't figure this out I will need to go another direction.  
Any other ideas?  Thanks!

I wondered if it might be related to the gain setting on the preamp, but it didn't make sense to me.  I will try changing the gain setting and report back.  Thanks for the suggestion!

I wonder if you are overloading your integrated amp with a over-gained phono signal.

i have the Lyra Delos, and I have a Whest ps.30r phono preamp with variable gain. When I use it at 60db gain, I have no issues. When I use it at 65db gain, it overloads the preamp (Audio Research LS-25).  

I also had had the same issue in the past with a variable gain PS Audio phono pre and the same ARC preamp, and a different cartridge.  Too much phono pre gain, and the signal cracks and pops when it got to the ARC LS-25.

no issues now, I just keep it at 60db gain.

hope this is helpful...
