Product Description

The Graham Slee Solo SRG Green headphone amplifier is a newly updated 2009 version of Graham Slee's 'Intro', one of our most popular headphone amplifiers ever. The Solo brings to headphones the hidden accents and dynamics that few loudspeaker systems can emulate. Listening to headphones through a good headphone amplifier after being used to speakers can be a surprising experience - revealing detail and musical texture you've never heard before.

The Solo doesn't use any electronic tinkering to achieve its emotionally evoking performance - it simply enhances the performance of the widest range of dynamic headphones up to and including the best models available. Its the perfect companion for any pair of high end headphones and unrivalled at this price. The Solo includes two inputs which you can switch between on the front panel . For those who like to share something that sounds so good, you can also use the a Y-cable adaptor to use the Solo Intro with two pairs of headphones.

The Solo SRG Green is supplied with standard 'plug top' power supply. We also stock the Solo SRG MC headphone amplifier, which is the same but includes the better PSU1 power supply. The PSU1 is also available in store, so you can upgrade this headphone amp to MC spec at a later stage if you wish.

    I went for a demo at Audio Affair for some headphones and also needed a headphone amplifier. I had to return the one I had bought as I had made a mistake and Audio Affair really made it easy for me to take back the one I had bought and refunded the full cost straight away. I had my eye on the Graham Slee range for some time so ordered the Solo SRG II Green headphone amplifier and I am not disappointed in any way. Solidly built great sound that just gets better and better the more you leave it on. Graham Slee suggests you keep it powered on except if you are going away for a while on holiday. Did I mention? Made in Yorkshire. At a very reasonable price and built like a tank. I can't thank the guys enough at Audio Affair for helping out. Go on buy one! You won't be disappointed.

    I bought this amp having had the Sennheiser HS650's for about a year before I bought the amp. The amp adds lovely colour and sound to the headphones, they sound brighter than before which might be some to peoples tastes or not. I think it makes a great difference. Having a good source makes a difference but not as big as some people fabricate it to be imho.
