Great little headphone amplifier.
The Graham Slee Solo Ultra Linear Diamond Edition Headphone Amplifier (hand made in England) is a great little headphone amplifier.
The Solo ULDE is my second Solo (I also own the Solo SRGII) and find them both to be marvellous.
I found that in both cases, initial sound improves after a significant period of use and that the Solo has a warm, smooth, musical, and expansive presentation.
Used with PC (FLAC) Arcam irDAC GS Solo ULDE Sennheiser HD650.
I have enjoyed countless hours of listening through the Solo and recommend it without hesitation for similar applications.
