Graham Slee Solo ULDE Headphone Amplifier Graham Slee Solo Ultra-Linear Diamond Edition headphone amp & PSU-1 linear power supply Price includes shipping Herbies adhesive isolation feet Bought five years ago from official Australian distributor, moderate use, operates flawlessly Happy to answer any questions Condition: Excellent Payment Method: EFT, Cash on Pickup, PayPal (gift) Region/State: (NSW) New South Wales/Australia By was_a 0 Comments AUD $600 Date: October 13, 20241 yr
A$600 is fair-to-good for a Solo Ultra Linear in excellent condition; it is not a steal, but it sits in the sensible zone for a quality used Graham Slee amp. New pricing for this model has sat around the equivalent of roughly A$1,200 in past listings and reviews, so A$600 lands at about half of new, which is a solid used value rather than an ambitious ask.
What makes it worth buying is the Graham Slee house sound: quiet, clean, and very controlled, with enough drive for a wide range of headphones and a reputation for excellent timing and clarity. The “excellent” condition matters here because these are simple, well-built units rather than temperamental collectibles; if it comes with the correct power supply and no channel-balance or switch issues, this looks like an easy recommendation for someone wanting a refined, no-drama desktop amp.

Graham Slee Projects, founded in 1998 in the UK by engineer Graham Slee, traces its roots to his extensive career beginning in 1974. Starting in audiovisual engineering, he advanced through printed circuit design, electronics manufacturing, and broadcast audio, serving as a senior engineer for BBC studio contractors before freelancing in hi-fi. This deep expertise laid the foundation for a brand dedicated to precision audio electronics, all handmade in British workshops.
The company specializes in phono preamplifiers and headphone amplifiers, developed in tandem since 2000 to mutually enhance performance. Flagship phono stages like the Accession MM, Reflex M, Era Gold V, and Revelation excel at extracting superior detail from vinyl, while headphone amps such as the Solo Ultra Linear and Novo deliver refined, high-fidelity drive. Graham Slee also offers DACs, focusing on compact, synergistic components for vinyl enthusiasts and headphone users rather than speakers, turntables, or cables.
Positioned as a niche boutique in the high-end hi-fi market, Graham Slee earns acclaim among discerning audiophiles for its uncompromised sound quality and value. Free from mass production, its products prioritize musical transparency and build integrity, appealing to serious vinyl collectors and headphone aficionados who seek understated excellence over hype.
