experiencing distorted playback with Benz Ruby 2

Guys...after spending some time with a test record and tweaking, I noticed on the vertical tracking test the needle was almost bouncing out of the tracks in the 19-20Hz range. I increased the tracking force a bit and this went away.

Now the thing sounds awesome! I can't believe it is so sensitive, but it must have been a simple setup issue. I actually measured the tracking force at 1.9g, but I am thinking there must be a problem with my scale. It "felt" lighter than the 1.9g, and now it feels about right. I think I will invest in a new force gauge to make sure....but listening is believing.

Any other tips are certainly welcome..

Agree with Chayro. Unless you're listening to a filthy or damaged LP, "crackling" sounds are noise (an addition TO the signal), not distortion (a modification OF the signal).

The improvement from increasing VTF confirms that, and stylus mistracking was my first suspicion. Letting a sharpened diamond bounce around in a plastic groove will cause irreparable damage to the LP. Good thing you diagnosed this so quickly.

Another suspect would be dirty/loose connections between cartridge pins and tonearm wire clips. Make sure those are clean and snug. If you have a loose fit, slide a wooden toothpick into the clip and squeeze gently to snug it up a bit.

An accurate VTF scale is critical and need not be expensive. You shouldn't have to spend more than $50. Audiophile approved scales costing hundred$ are no better than a jeweller's or gunmaker's scale with a DIY'd weighing step.

Make sure you're weighing at record level and that the magnets in the cartridge are not being pulled toward any ferritic metal in the scale. Be careful! The magnets in a LOMC are powerful... a cartridge can destroy itself in a second if it whips out your grasp and crashes into something.

Please note, no scale can do more than get you in the right ballpark. Every cartridge is unique. Final tweaking of VTF (and some other setup parameters) can only be accomplished by listening. This sort of tweaking can wait until you get more used to the sound and more comfortable with delicate adjustments.

Until then, be *certain* that your stylus is not mistracking (and ruining your records) by operating the Benz near the upper end of its recommended range. Running with VTF too low has trashed more records than all other causes combined. Pay special attention when playing the inner grooves of tough-to-track LPs. That's where mistracking is most likely. If you hear that "crackling" or "fuzziness" again, STOP playing and increase VTF and/or anti-skating until it goes away.

Oh... and have fun!

Thanks a lot for the detailed thoughts. As I also explained to the poor guy I bought the cartridge from, this is my first time ever playing around with a cartridge of this caliber. I was initially concerned that I was putting too much tracking force on it...but, as you elucidated, one has to trust ones ears at some point in the process.

Thanks to both of you for pointing out the distinction between noise and distortion...makes perfect sense. It seems that what I was hearing was the needle lightly leaving the surface of the groove, and likely damaging that particular Beatles album. Luckily, I did catch it quickly and the record subsequently sounds great.

I spent last night in listening bliss...the cartridge now reveals all kinds of new things in records I have listened to several times in the past. Quite a bargain, when you consider that my entire record collection is now brand new to me.

Well, I'm glad you got everything sorted out. Now, all you need is a decent phono stage. :)

perhaps the next upgrade....the system can always sound better! That's what drives us. That, and maybe some level of insanity, as well
