A few things we get asked most often. If your question isn't here, our team is happy to talk it through.

Graham Slee is based in the Sheffield area in England, and the company states that its audio components are designed and handmade in Britain. Products are individually built and analyser-tested by its small engineering team in the North Midlands rather than being sourced as finished OEM designs.

Phono amplification is what most listeners associate with Graham Slee. The company has been building specialist MM and MC phono stages for decades, from relatively affordable models such as the Gram Amp series to the Reflex and Accession designs. Premium Sound’s current Graham Slee range is entirely focused on these vinyl products.

Start with the cartridge fitted to your turntable. Moving-magnet and moving-coil cartridges have very different output levels and electrical requirements, so the phono stage needs to match the cartridge type. Premium Sound currently carries separate Graham Slee ranges for MM cartridges and low-output MC cartridges.

MM and low-output MC cartridges place different demands on gain, noise performance and input loading. Graham Slee tackles them with dedicated circuits rather than treating MM and MC as two settings on the same universal input. This also makes choosing a model more straightforward once you know which cartridge type you are using.

The range gives you a fairly clear upgrade path. Gram Amp models are the accessible starting point, Era Gold V moves further into dedicated MM performance, and Reflex sits higher in the range. Accession is the most advanced MM option currently stocked by Premium Sound, adding Graham Slee’s more unusual approach to cartridge and record equalisation as well as greater adjustment.

Accession handles cartridge response and record equalisation as two separate processes rather than correcting them together in a conventional single EQ stage. The MM version also provides selectable loading, different record EQ options and both fixed and variable outputs, making it considerably more flexible than a basic phono preamp.

A built-in phono input can be perfectly adequate, particularly with a straightforward turntable and cartridge. A dedicated Graham Slee stage becomes more relevant when you want the phono electronics matched more closely to the cartridge, lower noise and a vinyl source that can keep pace with upgrades elsewhere in the system. The important part is choosing the stage around the cartridge rather than upgrading simply for the sake of adding another box.

The range is especially popular with record collectors looking to get more from a turntable without changing the whole system. Graham Slee phono stages cover moving magnet and moving coil cartridges, with options for entry-level vinyl systems through to more revealing analogue setups. Models such as the Gram Amp, Era Gold, Reflex and Accession lines have become familiar names for listeners who want a clean, natural signal from their records.

Graham Slee also produces headphone amplifiers, power supplies and related hi-fi accessories, giving the brand a useful place in both vinyl and personal listening systems. The design approach is straightforward and purposeful, with an emphasis on sensible circuit design, reliable build and musical presentation. For many customers, the appeal is that these products are easy to fit into an existing system while still making a meaningful difference.

If you are choosing a Graham Slee phono preamp, it is worth matching the model carefully to your cartridge type, system quality and listening habits. A moving magnet cartridge needs a different input stage from a moving coil cartridge, and the right pairing can have a noticeable effect on noise, dynamics and tonal balance. For headphone users, a dedicated Graham Slee headphone amplifier can also be a good upgrade from the basic headphone output found on many integrated amplifiers, DACs or streamers.

For vinyl playback, headphone listening and compact hi-fi upgrades, Graham Slee offers a focused range of British audio components with a long-standing following among enthusiasts.
