copy British sound solo diamond version super linear headphone amplifier
This is the new Solo version of the Solo Ultra Linear from Graham Slee. According to the manufacturer, this version of SOLO can easily drive high-speed dynamic headphones such as Senhai HD800, Sennheiser HD600, HD650, etc. When driving low-impedance headphones, the sound quality is better than previous products. It is praised by overseas HI-FI audio and is one of the representative advanced headphone amplifiers in the UK.
1: The noise floor indicator is excellent, so you can't distinguish whether the machine is turned on or not.
2: The fineness is improved again, the original design is optimized with materials, and the pure aluminum casing and pure aluminum knob are specially customized. The overall feeling is better.
The Solo amps have two RCA analog inputs, selected by a lever on the front panel (the middle of the lever is muted).
Note that the Solo amp has no built-in decoding, only analog input, and is a pure analog amp.
If the user only uses one input, it is recommended to close the unused RCA input with a metal protective cap to improve the purity of the background.
