Adding choice to our value proposition

The OM 1S is a magnetic cartridge (MM) with a Spherical shaped stylus that provides balanced and distortion-free playback for general purpose applications.

If your tonearm has a standard headshell or a cartridge mount, then step up to optimal sound reproduction with OM’s. A glance at anyone of these cartridges will reveal Ortofon's answer to perfect tonearm matching. Ingeniously tucked into the top of the mounting bracket is a tiny, removable weight-plate.

If your tonearm is an standard tonearm, just leave the weight-plate.

If your tonearm is one of the low mass types, then simply remove the weight. The mass of your OM cartridge is now a mere 2.5g

Great shop for vinyl and all things hifi and Audio visual. Staff are friendly and knowledgeable and won’t try and sell you what you don’t need . Recommended!

Great price, prompt service and a help line with somebody who was human and helpful when I got stuck setting the amp up. 
Recommended.

I know it's habitual to shop with the big names like Currys. But you won't find anywhere near this level of service from them, and I'll be sure to keep Holburn in mind for the future. Can't recommend them enough!
