The Pamphili chassis is a thick polished Alluminium cylinder with a top and bottom cover made of 20mm thick polished black acrylic, both these materials are particulary good to control and to dissipate vibrations.The cylindrical shape of Pamphili enables dissipation of vibration and a very high structural rigidity.
The Pamphili phono preamplifier is provided with a special kit of 1% tolerance metallic film resistors to fit the more unusual and exotic cartdriges presenton the market. The RCA connectors are especially designed to obtain the best possible sonic performances. The input connectors are palladium plated because they have been found better than the regular goldplated ones during sound tests. All RCA connectors have a Teflon® dielectric for the best insulation possible. The inside power supply is particulary well designed and very large considering usual phono preamplifier uses much simpler ones.
The power supply is inductive power obtained by 3 "transfomers" two of them working as AC dampers. The filter is made by 130000mF high quality electrolitic capacitors by-passed with PTFe caps. Internally the Pamphili is totally insulated, decoupled and shielded.
