Tracking error or ??

It was also be advisable to confirm your recently jack-hammered Way out West LP is OK by tracking that passage with another pickup or two.

I like this idea above from @boothroyd. Do you have any local audio buddies with vinyl rigs that you could play that same passage to see if it mistracks on their set up?

If it’s not an A/S issue, could it possibly just be a bad vinyl pressing? It seems as though you do not have this issue on the majority of your other LP’s.

As a side note.... I have the original Naim ARO on my LP12 and absolutely love it!  I'm happy to see that Naim is resurrecting this great arm.

Best wishes,

Dear @rauliruegas, I have to take issue with you your comment....

"Btw, the Aro is an unipivot and not a good tonearm for any cartridge"

Have you ever listened to the Naim Aro?  Have you ever compared it to other arms on the same table with the same cartridge?

Well, I have.  I have compared the Aro to Linn's Ittok and the Ekos on the LP12 with the same Benz Wood Bodied moving coil cartridge in the same system and have found the musical reproduction to be quite superior to that of the two Linn arms.

To blatantly declare the Naim Aro as being a "not good tonearm for any cartridge" simply based on the fact that it is a unipivot design, especially if you have never spent any time with this arm, I would consider this statement to be very short sighted and a very poor comment to be spreading on the internet.

There are many, many people who happen to love how the ARO performs on their LP12's throughout Europe as well as the USA.  But sadly, according to your statement, I must assume we all must have tin ears.

Best wishes,
Don

I absolutely agree.... you have to consider the table, arm and cartridge as a complete system.  An arm and cartridge can certainly sound better or worse on one table vs another.  But, if you compare my nicely set up LP12/ARO/Benz S-Class Zebra Wood Ruby to a different table/arm/cartridge of your choice you may find that they both are capable of reproducing music in a very pleasing and satisfying manner.  Will they differ in some aspects?  Sure.  Some people prefer... belt, direct drive, idlers.... some people prefer high mass, others suspended designs, etc.  My point is compare the table/arm/cartridge as a complete system.

As I had said... I compared these arms (the Linn Ittok / Ekos & ARO) on the "LP12". I, and many others are of the opinion that the ARO sounds superb on the LP12.

How does the ARO sound on other tables, I have no idea as I have not tried it on other tables.  However, as much as I love my ARO on my LP12, I would not and did not say that the ARO would outperform other arms on other tables.

My point of contention is that Raul blatently stated that the ARO "is not a good tonearm for any cartridge" period... as if that is 100% fact, or the Bible's Truth.  

Everyone is certainly entitled to their opinions and I realize everyone has the capacity to "hear" things differently and have their own sonic preferences.  But to "my" ears and in my humble opinion, the Aro presents music in a natural and organic way. Very much in the same manner that I hear when I perform in live acoustic events; both with my Montagnana cello in classical settings and my trombones in various jazz venues.  Nothing sticks out or sounds out of proportion... it's very evenly balanced.  It captures the dynamics, the full beautiful tones and harmonics, the timing of the music and presents it all in a very believable way.

In any case... I truly hope you will be able to sort out the periodic right channel distortion.  Please report back when you have it figured out as it may be helpful for others on the forum as well.

Wishing you all the very best!

@speakermaster:  Regarding ..."the vinyl pressings can have distortion on highly modulated peaks that are not there on others especially at the end of the record side."

I find this interesting and would like to learn more about this.  Out of curiosity, could you share which cartridge and tonearm you are using when this happens?

I ask because I wonder if when this happens if it has anything to do with which type of stylus profile the cartridge has, or if it has something to do with the type of tonearm... gimbal or unipivot, etc.

When this happens... is the distortion just in the right channel or is it in both channels equally?

I wonder if it is groove wear or does it happen on brand new vinyl as well?

Best wishes,
Don
