LPU V Phono Pre-Amplifier

LPU V DHT Phono Pre-Amplifier

Let Your Vinyl Come Alive

LPU V is our top of the line 45 Directly Heated Triode power output tube based Phono. LPU V offers the most alive, holographic and transparent presentation of music. It is part of our Performance Level 5 line up that represents a no-compromise & no-expense-spared design philosophy.

The input stage of the LPU V employs the EF37A- the octal version of the superb sounding EF86, both of tubes that were emplpyed in the RTR tape recorders in the early 1960s, directly respsonsible for the superb analogue recordings ever created. The interstage/driver is based on the musical and well known 6SN7 double triode. The output stage is now based on the 45 DHT power valves. LPU V is at the penultimate level of any phono stage, making it the most natural and organic sounding pre-amp for any turntable.
