Korf Audio TA-SF11R Series II Premium 11” Tonearm Removable Headshell
PREMIUM model
Korf Audio TA-SF11R Premium
Transcription length tonearm with the best quality of motion and rigidity.
Perfect for every transcription turntable, from Garrard 301 to Technics SP-10R.
PREMIUM Model
- Affordable super quick worldwide delivery
- Choose between round compact JIS-type mounting base or a sliding SME-type base. Or get both!
Hey, what's the deal with the PREMIUM serie? What changed?
- Better steel grade for the arm tube, polished instead of brushed
- Brass rather than aluminium parts
- Premium OFC wiring
- Full ceramic silicon nitride vertical bearings instead of hybrid ceramic in the regular version
The effective mass of the Premium model is 1g higher than that of the standard TA-SF11R. All our tonearms perform exceptionally well with cartridges featuring compliance up to 25–30, such as the Shure V15VMR. This Shure, along with the Ultra 500 and the Grace F-9, are part of our reference cartridge collection.
We test all our tonearms with a wide variety of cartridges to ensure maximum compatibility.
On the low-compliance front, we test all our arms with the GE VR 22 "Golden One" (compliance 3–4), as well as with the Denon DL-103 and SPU cartridges, of course.
The only cartridges that are definitively incompatible with our tonearms are most models from Grado and the older budget series from ADC.
This makes the TA-SF11R Premium especially suitable for low compliance, high energy cartridges like Koetsu.
We are always looking for ways to improve. Through three years of production, we have learned enough to take the performance of our tonearms to the next level. The sonic difference is really audible on full-range systems. Here's what we have done:
- Stainless steel vertical column, giving a more solid foundation to the whole tonearm
- Steel vertical shaft for deeper and more defined bass
- Internal redesign for even more rigidity
- Simpler, cleaner, more premium look
- Completely new azimuth adjustment mechanism for smoother setting
- Warranty extended to 3 years now
- We used this opportunity to completely rid the tonearm of all structural set screws. Now the only one left is the one holding the arm lift

Not included, but needed for operation:
- 5-pin MDIN cable to connect your tonearm to your amplifier
- Pickup cartridge. If you are curious about compliance and effective mass compatibility, please use our calculator.
- An electronic downforce scale
If you are mounting the tonearm on a wooden plinth, suitable wood screws should be sourced separately.

- Zero starting torque/no stiction
- No bearing chatter
- Great tracking of warps
- Less inner groove distortion
- Lasts forever — no servicing, no lubrication
- Not influenced by temperature/humidity/dust/age
- Easy to replace if broken
- High bending resistance: 3 times higher than aluminium, 2 times higher than titanium of the same mass
- Low energy storage
Why is steel seldom used in today's tonearms? It's not possible to simply replace an aluminium or titanium arm tube with a steel one. A whole new design is called for.
- Better strength and precision
- Less chatter compared to closely spaced bearings
- Low starting torque/stiction
- Better resolution
- Sharper dynamics
- Better sibilance control
- Less inner groove distortion
- Need no servicing or lubrication
- Better mounting precision
- Ease of adjustment
- Better plinth coupling
It would be a real shame to spend so much effort (and money) on our beautiful bearings, and then ruin their performance with a weight on a pulley. Or with a sliding lever.
Our magnetic antiskating is calibrated and uniform—the biasing force remains the same from the outer to the inner grooves.
- Steel load-bearing part; aluminium alloy locking collar
- Press-fitted into an armtube
- Spring loaded, gold plated contact pins
- Nylon isolator
TA-SF9R comes with a precise alignment gauge. It's easy to set up your cartridge exactly right in minutes. Even away from your turntable, at a comfortable well lit desk.

What Makes Korf Tonearms Special?
The Korf tonearms are a clean sheet rethink of what a tonearm should be. We focused on our audio priorities: quality of motion, rigidity, low energy storage, signal integrity, stability and longevity.
- Korf tonearms use aerospace-grade, zero stiction flexure bearings
- Korf Audio is the world's only maker of fully ceramic headshells
- Stainless steel arm tube is 3x stronger than aluminium, 2x stronger than titanium
- There is a lot more—click the button below to discover!
You will immediately hear the sonic benefit: Korf tonearms offer unmatched clarity, holographic imaging, real life dynamics, true tonality, sparkling highs and a really deep bass.
