It does not look like a low rider to me.

Is your arm truly parallel to the vinyl? Hard to tell from the picture, but your arm looks a bit dropped at the back, and that affects VTA/SRA.

The cantilever looks good though. Low riders generally look like their suspension has failed. Yours does not.


Thanks Peer - Based on my eyesight and using many magnifying tools, I believe the arm is fairly parallel to the vinyl - so I should be good there. Thank you for your thoughts and confirmation on things, as I had that 'here we go again' moment... :)

Vin, I believe you have your answer :D :D :D


Finally got the settings changed to IEC on my Moon 310LP and no more excessive cone pumping. :D

Not sure if I have sacrificed anything by doing so from an audio quality perspective, but I am a lot happier knowing that I am not overworking the speakers unnecessarily and things still sound pretty good to me! ;)

Thanks for the tip on this Harry and especially as this came from Simaudio too!

Cheers,
Vin.

The IEC recommendation to cure woofer pumping is mentioned in the 310LP Owner's Manual.

Thanks John - Yes, I had seen that but I have been trying to solve the issue without needing to resort to the subsonic filter and I had read that if one could, to try doing so without introducing such a filter as it may be detrimental sonically. I tried everything I could (even had my Lyra checked out which took 4 months!) and this was going to be my last resort which of course, ended up being the solution...

Cheers,
Vin.
