Questions to ask as I shop for a tonearm?


I’ll be upgrading in 6+ mos. I’m asking now because I’m still learning. I want to take plenty of time to understand the relevant technical aspects of something so complicated & what makes one person love brand X & another person dislike it.

I have a George Warren tt & a Sumiko Blackbird cart I’m waiting for to put on the stock Rega 250. I’m also waiting for Christmas to hookup a Jolida JD9 mkII.  My budget will be ~$1500. While brand & model suggestions are appreciated... I want to learn about tonearms. As always, I appreciate the knowledge you all pass on to me.

@toschsii,
You're being very smart to ask those questions. It's a complicated and often frustrating subject for some. You are lucky that there are many helpful experts here. I would suggest paying close attention to comments from
@almarg @raulariegas @nandric, @chakster, @lewm, @dgarretson, @atmashpere who all make regular contributions on this topic.

I'll mention one tonearm consideration that you should familiarize yourself with:
The relationship between tonearm and cartridge. Resonance is a big concern with a known and agreed upon range of what works best. Too low a resonant frequency or too high will cause huge problems in sound quality and tracking ability. vinylengine sit has a resonance calculator that is a well-known tool that lets you consider the compatibility of any given cartridge and tonearm. It's not perfect, but it is a perfect place to start to understand the concepts and get lead you in the right direction. Pair a cartridge and tonearm that lead you to a resonance in the green range. One quirk is that Japanese companies present different specs than most Euro or US ones, so if considering a Japanese cart, by sure to convert the specs so you get "apples to apples". (This will make more sense after a bit of reading). 

Though not about tonearms, another important aspect to understand is the relationship between cartridge output and phono stage gain. Carts put out very small signals. Phono stages, or phono sections of preamps that have them built-in, add a certain amount of additional gain(often adjustable). To get reasonable performance you need to have enough gain but not too much. Some very low output carts needs an extra boost(step up transformer). Moving magnet carts need less gain, moving coils more. Many phono stages are made to focus on one or the other, some both. Making sure your phono stage has appropriate gain settings and loading options for the cartridge is a critical step to enjoying vinyl.

I'm sure plenty will chime in with good advice Cheers,

Have you asked the manufacturer what arms they believe, works well with their table?

Shouldnt they should be the most qualified, I hope so!
I don’t think any of the modern arms under $1500 can do it better than classic japanese tonearms. Here is what i am using along to some others which does not fit into your price tag.

These arms are all under $1500:

Lustre GST-801 - with two different counterweights and additional ringweight is fine for many cartridges from mid compliance MM to high mass low compliance MC. Magnetic tracking force and anti-skating, silver wiring, vta on the fly.

SONY PUA-7 - very easy to use/adjust for many cartridges, comes with additional sub-weight for heavy MC. Just make sure the arm has its VTA on the fly and armrest like this.

Technics EPA-100 - also very easy to use for MM cartridges and some lightweight MC, rubby ball bearings, unique counterweight with dynamic damping option. Many info online. Not good for heavy headshells and heavy cartridges! Great tonearm.  

Victor UA-7082 - long version of the popular UA-7045, very nice tonearm with vta on the fly, easy to use and adjust quickly. One of my favorites. Designed for the best DD turntable made by Victor/JVC (TT-101).

Denon DA-401 for high compliance MM cartridges only !

P.S. It depends on your cartridge, but you can’t go wrong with any of the arms from this list. Highly recommended!
