Hello, I am seeking your recommendation for a modern tonearm for my Ortofon SPU Royal A cartridge.

I have been using it with a vintage Ortofon RF-297 and want to try a modern tonearm. I understand the Groovemaster II can be ordered for Ortofon SPU-A cartridges. Can the Sorane TA-1L with a sliding base work for the Ortofon SPU-A?

Thanks in advance for your recommendation!

Yes. If you want to use the TA-1L, you have two options:

1. Buy a Ortofon APJ-1 adaptor (https://www.ortofon.com/apj-1-adaptor-for-spu-a-houses-p-582) which allows an A-mount SPU to be used on regular arms like the TA-1L designed for 50-52mm mounting collar to stylus distance. The 6 gram weight of the adaptor will increase the effective mass of the arm by that amount, but shouldn’t be much of an issue with the low compliance Royal.

2. Move the TA-1L closer to the spindle to compensate for the 21.5mm difference in mounting collar-to-stylus distance between A-mount and G-mount SPU. The correct amount is determined by some fairly simple geometry. You end up basically with the arm having a new effective length as well as offset angle. This is how I run the SPU Wood A on my Ortofon RS-309D tonearm.

If you want to try option 2, I will be happy to give you the optimum pivot-to-spindle distance and overhang. I would need to know the effective length of the TA-1L and its offset angle.

I haven't any experience with the Bokrand resto-mod arms...but I would prefer a Groovemaster vs Schick in this instance. ( there are places the Schick would be my preference but, for me, not this one ).

Thanks for the suggestions. I have the APJ-1 adapter, but think #2 may be better because using an adapter might degrade the sound. Do you know the general sound charateristic of the Sorane TA-1L? Even though I'd like to try a modern tonearm, I still would like to have warm/full/big sound. Thanks!

I like warm/full/big sound in my analog reproduction and always thought the Schick sounds warmer and fuller than the GM, which is more cleaner and detailed.

Sorry, I’m not familiar with the TA-1L but I’m sure the basic full sound of the SPU will be evident regardless of the arm you use.

The Sorane TA-1 and TA-1L do work very nice with SPU.

I can see that you have the TA-1L. Which cartridge do you use with the TA-1L?

I also see that you have the Glanz MH-124s. I cannot afford the MH-124s, but was wondering if you are familiar with the entry model, MH-10B?

Thanks!

In what sense, do you like the Bokrand for the SPU better than the other two? Does it sound fuller/warmer or cleaner/detailed? Thanks!

Both directions. More refined and more musical. My ranking and characteristics are:

bokrand: detailed, natural, sweet, well balanced
>
groovemaster: detailed but unengaging
>
schick: solid but coarse sounding

Bokrand is of course not a product but a restoration no?

Btw does anyone have FR64/66S experience with SPU? I don't although I use one with FR7 regularly. Something tells me that could be fun..

Use a modified Ortofon RF-297 with my SPUA--they are available on the S/H market for a reasonable price

Would be in my quest--I appreciate the synergy with the two of the same brand.

Good luck

Thank you for this question have been wanting to read on this for a while. Looked at a schick and a woody and became to difficult without hearing.

Gave up the trauma and just bought a Bokrand on line. Easier on the synergy level for me being an Ortofon arm once with an Ortofon cart. Also as it will be my first venture into SPU territory, eventually to be able to listen to some older recordings.

Hi, I am researching my options for a 12" tonearm for a Thorens TD124 restoration and have narrowed the decision to the Sorane TA-1L or the Groovemaster II. I see you have the Sorane, and just wondering if you have any experience with the GM, and if so how they compare? And should I be considering the Woody as well? Thank you.
