Tracking error or ??

Dear @daveyf  : """  I have heard a very small amount of distortion on a few other highly dynamic and highly modulated tracks. Always in the right channel, which would certainly seem to indicate that AS is an issue. """

I own the Kleos and is really good tracker with and with out A/S. Its compliance is almost high compliance at around 18cu-19cu. It rides with out true problem the whole Telarc 1812.

So if the Kleos is in good operation condition specially at the stylus tip and suspension then the problem is else where and could be the tonearm and TT. The LP it's not due that you experienced that trouble in other LPs.

Btw, the Aro is an unipivot and not a good tonearm for any cartridge. Please read again what mijos posted. 
Now, if you are in love with this Naim is up to you.

@rauliruegas  Raul, I am not considering the original Naim Aro, I am interested in the new Naim Aro that has just been released on the Solstice table. I have no idea if this arm will be available separately, but if it is, then I think it could be a nice option.

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

IMO Any arm will have its pluses and minuses, including the Aro. Question is whether it works well on the table that one is planning on mounting it and with the cartridge that one utilizes. The LP12 is a severely limited platform for mounting after market arms, simply because its spring suspension really cannot accommodate just about all top flite arms. ( Due to the severe weight limitations that this suspension dictates). I strongly suspect that Raul is in fact correct. Hypothetically, the Aro if it could be directly compared to arms like the Basis Super Arms or the SAT’s or the Triplanar’s would come off in a very poor way. None of these arms work on the LP12. The Aro does. The question which I am contemplating is whether the excellent LP12 platform is worth sticking with given the arm scenario. Maybe it would be better to go to another table that allows for far superior arms to be mounted, albeit with possibly less general ability than the LP12??

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!
Don
