Another “How to choose an arm” question


I currently have a Sota Saphire running an SAEC We317 arm (221mm spindle to pivot and 12 mm overhang).

That is running a Garrott Bros p77i, but I have been looking at some LOMC cartridges, as well as SoundSmith LO-MI, AT ART, etc.

How is one supposed to determine their current arm is good or not?

It sounds fine and I would think that the knife edge design is not prone to a lot of wear.
However it was recommend that I upgrade the arm… But how would I know “to what”, and how would I know if the upgrade is worthwhile?

I was looking at some DD tables to have a more expanded choice of arms that can be mounted, as the Sota is a bit restrictive in that regard. That is still on the cards as a possibility… however assuming that the Sota is a keeper, then how do I determine the arm’s adequacy, being “fit for purpose”?

@mijostyn thanks mate!

@holmz Great News that you are to try out a Tonearm that has an attraction to you. I am sure you will start to notice differences immediately and the curiosity will be further ignited, you will not be alone in this, my daily mantra is 'What If', my talk on HiFi yesterday was with my friend who is almost completed a design for a Tonearm that could become a marketable product

Is it Alexy?
I was going to buy his, but the CB popped up used day before yesterday.

I am based in the UK, and not aware of a forum member known as Alexy.

The Tonearm I am referring to is at present a prototype, that has had a quantity of critical parts requiring outsourced machining, as it has been cost effective to do so, instead of having one part only produced.

The designer and builder/assembler also has the skills to machine a selection of the parts, but those parts that have to be 'minute dimension accurate' are best left to the services that work with the producing the tightest of tolerances daily and know the best practices. 

The Geometry and Mechanical Interfaces are complete for the Tonearm.

It won't be long before the mechanical interfaces to be considered for the TT assembly of parts are to be addressed, and the Cart' alignment is given a extra TLC.

Then when all is ready and functioning as designed for, I will request that a second Tonearm is assembled with PC Triple C Internal Wire, as my most recent experience has shown that there is a special attribute for this wire when used as the signal path within a Tonearm. 

I am hankering for, and really looking forward to the time when a Company produces a Cart' with this wire used for the coil and Lead Out Pins, it might just prove to be a New Break through.   

Dear @mijostyn  :  "  I do compare digital to analog versions of various recordings by synchronizing the record to the digital then just switch back and forth by remote. "

Comparing analog to digital versions in reality for me is really easy, the only main issue is that SPL be evenly for both formats.

One of my last comparisons was:

Diana Krall - When I Look in Your Eyes "

No contest here. CD version is way superior and I was surprised with because I was almost sure the LP been better than the CD. So I took in count that both recording versions were mastered by different gentlemans.

In this particular recording you can listen the differences for the better in the CD at the 2 minutes to listen both versions.

As many of us I own several recordings in both formats and usually in Original Motion Picture Soundtrack the CDs outperforms the LP versions even if mastered by the same guy.

In reality I'm not anal to take my time doing those comparisons. I'm  a way more interested to listen and enjoy my MUSIC sessions.

I was sort of talking about the idea of objective comparison, so they also would need to be sync’ed in phase/speed.

That last part sort of goes contrary to the majorly of your posts, which talked about bearing chatter and noises from the arm, that was the subject of the thread title.

@rauliruegas , Isn't it fun! You bet people would be surprised how it cuts both ways. In reality it is not being fair to vinyl as it has a steep up hill battle but, better is better be it the format or the mastering. What I really love are some of the BluRay concerts that are available like Return to Forever "Returns." It is almost as good as being at the real concert. The audio is spectacular. Another one is Mike Stern's Paris Concert with Dave Weckyl on drums. There are times when vinyl wins. It is like driving a manual. It takes more skill even if it is not as fast. That makes it more fun. Any monkey can slide a disc into a drive:-)
