can anyone recommend a person in LA area to pay to install a tricky Koetsu cartridge


Hi,

Assuming social distancing and stay at home order not violated, can anyone recommend a person in Los Angeles area that can be hired to install a Koetsu Rosewood Signature Platinum cartridge which I understand is a bit harder than most cartridges to install. I have a person or two but they are not currently available.

The one part of cartridge setup that really is tricky, at least in the sense of taking a good deal of time and skill to get it right, is VTA.

On the one hand VTA is the easiest of all. Is the cartridge body and/or arm pretty much parallel to the platter? Then you are done. 

But on the other hand very small, and I mean micro small, adjustments in VTA are pretty easy to hear. 

So what happens is, if your arm makes VTA easily adjustable, and if you try it and hear improvement, then you can spend as much time as you want getting it perfectly dialed in. Some even do this for each record. But if on the other hand your arm makes VTA adjustment a hassle, or you don't hear any difference, then don't worry be happy. 

Pretty much everything about turntables is like this by the way. Very fine adjustments in VTF, within the recommended range, make an audible difference. Every single aspect of cartridge setup is like this. Some guys throw their hands up and say here take my money you do it. Others roll up their sleeves and get the job done. The job by the way being endless- but you are the boss, you write your own checks, pay or don't pay the bonuses, and so of course its entirely up to you whether you fire the bum or give yourself a promotion.

I appreciate all the encouragement to do myself but am not inclined to do so with such a pricey cartridge.  This is especially true here where my turntable add a layer of difficult in that the Townshend Rock 7 has a trough with oil that the tip of the arm sits in.  The arm is a helius omega arm that is frequently used with the townshend rock 7.  The helius and rock 7 distributor has used this combo before but not sure with a koetsu.  He believes the arm is very compatible with the koetsu cartridge but because of the pandemic is not doing housecalls for the foreseeable future.

Give Brian Berdan at Audio Elements in Pasadena a call. He was trained in the art and science of turntable/arm/cartridge set-up by his pa, the legendary Brooks Berdan, and is now himself an expert.

Do you still have the cartridge alignment protractor supplied with the Helius Omega? It’s design incorporates a unique offset bearing design which renders a standard protractor unsuitable for the arm. If not, see if you can acquire one from the U.S.A.

Great table, great arm!

Yes I agree with other guys you want to eventually learn DIY on this, but doing it your first time on a $$$$ RSP is not something I’d agree with!

The (minor) additional challenges an RSP might pose are 3:
1. Older models will not have threaded mounting holes, requiring both a bolt and a nut to secure, rather than a single screw. Newer ones (last several years) should be threaded
2. The body is big and boxy which can obscure cantilever alignment lines on your protractor - and also makes azimuth and VTA / SRA harder to spot.
3. The low compliance will pose problematic for some tonearms - light carbon fiber arms and pure unipivots may not be the best idea etc. It will make even harder to "dial in" and may not be all that good even once dialed in.

If I were OP, I’d at least get a Denon 301 (also a low compliance Japanese MC cart) to practice with for a while (maybe on another table/arm) before trying his hand at the RSP. Paying a pro to enjoy the RSP in the meantime is a very good investment.
