E-Glo is an all valve design completely free of semiconductors in its signal path. Its valve complement consists of the classic glassware beloved of audiophiles: four ECC83s and two ECC88s. The use of these valves will ensure that supplies of replacement tubes are always readily available, while experimentation is encouraged for those who love to fine tune the sound of their systems by changing valves, such as E.A.T's premium offerings.
In the fully balanced input stage, E.A.T fitted a Lundahl step up transformer with an amorphous core, type LL1932. The unit's gain is 45db, plus the voltage gain of the step up transformer. E-Glo's amplifier section uses split, fully passive equalisation, without any equalisation in global negative feedback loop, which can harm the sound.
At this level of performance, only the best components will suffice. The choice of output capacitor is the highly praised Mundorf. All other capacitors are WIMA. Mundorf Connectors with Teflon insulation have been chosen for their unparalleled integrity.
To ensure the utmost flexibility and to ensure perfect matching to a wide range of cartridges the E-Glo provides capacitance loading for moving magnet cartridges in six user switchable steps from 47pf to 900pF.
To ensuring quiet operation the use of an external power supply, connected to the E-Glo via a special 9-pin connector, familiar to those who recall the legendary Cello Palette preamplifier. Its heart is a custom made toroid transformer. The transformer features double shielding between the primary and secondary windings. This avoids the intrusion of RFI, while acting as superior mains filter.
Separate power supplies feed the valve phono preamplifier because the best way to shield a mains transformer from electromagnetic radiation is to distance it from the electronics. Metal shielding alone cannot perform the task as well as a separate power supply.
It’s now some six years since EAT, already established as a maker of high-end audio valves, burst into the high-end turntable market with the spectacular Forte and Forte S.
EAT followed up with the E-Flat and its unusual tonearm. But with the new C-Sharp, EAT has moved into much more affordable price territory. EAT’s founder Jozeﬁna Lichtenegger is wife of Pro-Ject boss Heinz Lichtenegger, so it comes as no surprise that the turntables are manufactured in the same facility at Litovel in the Czech Republic. But although they clearly share some design heritage, the EAT products are quite different from anything offered under the Pro-Ject name.
Many turntables of the high-mass school are unwieldy-looking devices, where the record is perched up on a platter that’s as tall as it is wide. With the Forte, EAT took the lateral-thinking step of making the platter’s diameter larger instead, to create a high-mass design that looked really good: a turntable of classic proportions and elegant design, but on a heroic scale.
