Have recently bought a Leak Stereo 130. On the whole a good amplifier that offers good control over my Q Acoustics 3050i speakers. I do not fully understand why but specifically when a PC is connected to the USB B input, the sound is a bit too lean to my taste. I inserted an ifi Zen DAC, with its noise free power adapter, in between the PC and the amp and the result is extraordinary: full bodied sound and no loss of detail. MQA on top!
