Graham Slee Solo SRG II Headphone Amplifier 

The Solo stereo headphone amplifier started life in 2001, has seen a decade of continuous improvement and on its way What Hi-Fi? gave it five stars, warning customers to "be prepared to buy it there and then" if they dared to audition it.

Made for studio monitoring, the Solo is often used in commercial editing suites where it captures edit points so elusive to other headphone amps. It was also supplied to the BBC, modified to accept PO 316 (BPO) jack plugs. It is best partnered with studio headphones — for a headphone amplifier geared to driving the most difficult hi-fi headphones see the Graham Slee Ultra Linear Diamond Edition.

 

The Solo SRGII shares the same tape loop monitoring feature of the Graham Slee Ultra Linear Diamond Edition.

Proprietary "in-loop" headphone control feedback system corrects for headphone frequency dips and peaks.

Its AC coupled output stops DC current appearing across your headphones, preventing headphone burn-out.

Headphone sensitivity volume control: unlike conventional volume controls, this one is designed to be used over its full rotation to compensate for a wide range of headphone impedances and sensitivities. This avoids the use of gain switches which would otherwise result in differing performance characteristics depending on the gain setting.

The Solo SRG II headphone amplifier is supplied as standard with a silent running energy efficient power supply complying with world carbon reduction targets.

The Solo SRG II headphone amplifier can also be supplied with the PSU1 power supply (also available for separate purchase) for those happy with a traditional, more power hungry linear power supply.

        Good value and performance
        Saturday, 8 February 2014  | 

        My review is based on this amplifier used with a Cocktail Audio X30 and a FiiO X5 playing 192/24 and 96/24 Studio Master FLAC files and not on CD's or analogue sources.

        My headphones are Grado GS1000i's, Grado 80i's and Philips X1/00's

        I have no other headphone amp to compare this too however I can say that there is a very definite and noticeable improvement when using this amplifier with my sources than just connection the headphones directly. The soundstage is wider and the points of each source, be it instrument or singer, seems more focused. I am happy with its performance and certainly think it is worth what I have paid.
