Pros: hand made, great sound quality, high detail

Cons: pricey

"The Solo SRG II headphone amplifier has two line level inputs and a front panel input selector with centre off. It is housed in a strong anodized aluminium eurocard style enclosure. The volume control also acts as sensitivity adjuster and therefore the full rotation can be used . The Solo SRG II headphone amplifier is suitable for use with headphone impedances from 16 Ohms to 600 Ohms."

 

I bought this amp unheard based on the rave reviews from English hi-fi magazines and it did not disappoint. It runs my Grado 325i's as well as my HD650's beautifully. As stated above the volume acts also as a sensitivity adjuster so with the 300ohm HD650's i run it at the 3 or 4 o'clock position and the 32ohm grados at 12oclock.

 

My reviewer vocabulary is not good enough to describe sound characteristics but i do know it was leaps and bounds better than the Firestone fubar IV Plus that it replaced. (Please see the professional reviews in the link provided for better information)

 

A  word of advice for anyone wanting to purchase one of these. Buy the PSU1 power supply that is available as a combo. It is cheaper to purchase than if you are buying separately which I did.(US$350) After listening to my amp with the walwart type supply i decided to spring for the upgraded PSU and it made a significant and very noticeable difference in sound quality. Everything was suddenly more vibrant.

Overall I am very pleased with my purchase and am happy knowing that if i decide to keep it for many years it will still be a good quality amplifier.

Please note prices are converted from New Zealand dollars based on today's exchange rate. It may be available cheaper in the US.
