CB-A01 is a cost-effective way to elevate the performance of practically any turntable or tonearm. Alumina ceramic gives a unique combination of stiffness and light weight.
The nature of the ceramic material is such that slight discolorations and minor shape irregularities are inevitable. They make each spacer unique and do not constitute a defect.
Why is the Korf Spacer Better?
Made From Alumina Ceramic
Our experience with ceramics enabled us to bring you this spacer a at an affordable price:

  • Single seamless piece of alumina ceramics
  • Light and incredibly strong: as rigid as steel at less than half the weight
  • Spacers made out of carbon, metal etc also work—but do not offer an improvement of a ceramic one
  • Similar to 1980s Audio Technica AT633, but much better performing due to modern materials
Measurable Improvement
Some spacer sellers make fabulous claims—but have nothing but flowery prose to back them up.

We measured the tonearm's resonances with our spacer and without it. The results are clear as day: CB-A01 essentially eliminates the headshell resonance. You will instantly hear the difference:

  • Less sibilance
  • More "air"
  • Better feeling of space
  • Better stereo separation and depth
  • More focused bass
Easy to Install
  • Simply slides between the cartridge and the tonearm's headshell
  • Easily installed and removed—no glue or other permanent connection
  • Fits all cartridges and tonearms with a standard 1/2" (12.5mm) mount

CB-A01 comes carefully packed in a special protective sleeve. Take care when removing the spacer from the packaging, it is quite fragile.

Do Cartridge Spacers Work?
We have received many questions about the role and effectiveness of cartridge spacers — small flat parts that go between the headshell and the cartridge. This is an excellent opportunity to finally break the shrink wrap on my Audio Technica AT633 ceramic cartridge base
CB-A01 Ceramic Cartridge Spacer/Base
You might remember that we asked a question back in October — is a ceramic cartridge spacer/base something that might interest you? The answer was an overwhelming "yes", and here it is! I am glad that you, my dear readers, pushed me to build this ceramic spacer.
CB-A01 Specifications
Fits all the tonearms that use the standard 1/2" (12.5mm) cartridge mounting system. If you are worried about the spacer's mass and its impact on tracking, please use our Tonearm/Cartridge Matching Calculator. Most arm/cartridge combinations work fine with CB-A01.

  • Single seamless casting, material: Alumina Ceramic
  • 1.5 mm thin
  • Weight 1.8 gram
  • Treat like thin glass!

Note: there are some cartridges that need very light or highly resonant headshells to sound good. Such pickup cartridges would not benefit from using a ceramic spacer.
