Sorry for the slow reply and thanks for the great info Kurtster. That diagram is very useful, thank you.

I'm hearing the distortion when I push it too hard on busy, bassy tracks. I just took a reading with my RadioShack SPL meter (weighting C, slow response) and I am good up to about 88 dB. Anything over that starts to break up in busy, bassy sections. I guess I need to follow Golear's advice and keep it to around 85 dB max. Most music just sounds better loud though! I think all these years of loud metal concerts might have damaged my hearing! :mrgreen:

Have I ever suggested that perhaps it's finally time to upgrade those speakers? ;)

Ha ha yes Jonathan once or twice! It’s on the list, when budget permits...

I'm happy to report that I have resolved my issue. It occurred to me that my repaired MIMC Star now had quite a few hours on it and perhaps the suspension had settled some. The bass was sounding very full on many tracks and I had lost some high end air. So I moved the arm up two full turns of the VTA tower and now sounds much better. More air, and bass slightly less full. Also listening at max ~85dB. No more distorting kick drum.

Thanks for everyone's help.

P.S. Jonathan - doesn't I mean I don't still want new speakers eventually!

....and pretty soon, you'll be adjusting VTA for each LP. Enjoy! :-)

Ha yes I can see myself doing that. I really can hear it when it's just not "right".

Another update here. Replacing the stock Prime footers with Terracones and putting IsoAcoustics devices under all components and speakers has improved things further. I am right now listening to Rage Against The Machine's brilliant debut album at consistent 91-93dB :shock: without any distortion or break up at all. Sweet!
