Shi Hui Liu has done it again. The mastermind behind Opera Audio has developed a phono preamplifier for lovers of natural music reproduction who do not necessarily use a tube phono preamplifier, but want to take advantage of the homogeneous sound image. Based on the circuit of Consonance's tube phono preamplifiers, Liu has developed a pure MM phono preamplifier (PM-11) and its big brother for MM & MC (PM-13). Both models can be further refined sonically with an optionally available battery-powered drive (BPS).
The PM-11 uses the same MM design as the PM-13. Two discrete JFET transistor amplification stages with a passive RIAA equalization and negative feedback free design allow highest, interference free music enjoyment of your MM cartridge. The special construction is especially convincing in quiet passages, where the absence of noise is the most beautiful, especially when you capture the details of the music completely new. The whole design-fully packed in a small housing made of solid brushed aluminum. Not only sonically a feast for the eyes.
