The LPU III is a further development of the great sounding LPU II.
It is characterised by a more powerful dynamic sound with natural, life like presentation- a combination that we look after in analogue playback.
The classic RIAA circuit is made of specially selected materials & components out of production and only available in limited quantities.
The input stage utilises lush sounding EF86 valves, which drive active RIAA equalization network (without series resistors), which is amplified by the EL84 power pentode, triode connected on the output stage. The low output impedance EL84 power output stage is choke loaded in order to deliver supreme dynamics and punchy bass. Choke loaded anode of the EL84 valve make any conventional resistor loaded sound lame and dull in comparison.
LPU I, LPU II and LPU III family of Phono Pre-Amplifiers share similar tube input stage- a pair of EF86 pentode tubes. Due to the brilliant sound character of the EF86 those tubes were commonly used in many radios and RTR tape recorders in the early 60s. The idea of their circuit design was borrowed from the input stage of early Reel to Reel (RTR) tape recorders, which were used in the mastering studios and radio stations. Maybe that is one of the reasons as why most recording from the 60s are sounding at their best, much better than from the 70s and 80s? In a way, the EF86 input tube design closes the loop and makes all our LPU Phono Amps range a time-less classic.

Ordering
We do not recommend purchasing a key system component without first auditioning it carefully, which is why we have demonstration rooms and a 14 day trial period policy. However in certain situations it can be difficult for people to get to our showroom and for those instances we can offer our mail order service.
