A headphone amp renowned for superb linearity and open sound, Graham Slee Solo UItra Linear Headphone Amp has brought delight to many headphone fans. QA remake model of this famous headphone amp will bring additional joy for a similar performance at a much more affordable cost.
Using the best parts available for the components involved elevates the product value even higher, as it is always entrenched in QA’s values the sum of all these high-quality parts can have a great impact on the overall improvement of the final product if implemented well. Elna Silmic II, Nichicon MUSE & Gold, BC, WIMA, Vishay and ALPS are some of the biggest names in the components used in the assembling of this remake model. Soldered entirely with WBT 4% Silver content solder, the sound is just pure and pristine.
Externally, the chassis is a fully silkscreen-labelled alumimium case that speaks sturdiness and solidity. Volume control is fully CNCed from solid aluminium instead of silver-painted plastic knobs, giving a very tactile and smooth experience in adjusting the output gain. Dual input switch on the front control which inputs of the selectable two to be used, great for connecting multiple sources without the hassle of plugging them in and out. Both the RCA inputs and 6.35mm headphone jack are gold-plated – of which the latter is not in the original model. The size and grip of the ground nut for the ground binding post is also considered with care to allow ease of use with aesthetical assurance.
The careful combination of various high-end components in the board are paired with one of the popular op-amps (easily changeable) from Analog Device, the AD823. Textures and timbre of the sound will be the immediate character of the sound, where nuances and details of various instruments will shine through. The air surrounding vocals will present a high level of realism without losing the musicality. Most importantly, the trait of Solo Ultra Linear is the ability of controlling distortion often found in some headphone amps when driven to a high level. This remake model inherited this trait and poses no problem in supplying the gain needed for high impedance headphone, maintaining the linearity throughout.
