EAT E-Glo Hybrid Tube Phono Preamplifier

"Goes Right to the Center of Your Brain That Loves Music"

It's a genuine feast for the eyes. The E-Glo premium MM/MC phono stage from the European Audio Team EAT looks and performs like no other, with a design so clever and attractive that owners will want to give it pride-of-place in their sound systems. In every way, it complements the stunning Forté, Forté S and E-Flat turntables from EAT just as it will bring out the best with any high quality turntable.

"Not all components, regardless of price can deliver this experience. It’s more than just 'going to 11' the E-Glo goes right to the core of the center of your brain that loves music. The highest compliment I can pay the E-Glo is that it takes me there," notes Jeff Dorgay in TONEaudio magazine. Playing side by side up against some phono stages from more established models in the $10k - $13k range, the E-Glo holds its own on all fronts."

All-Tube Design, No Semiconductors in the Signal Path

The E-Glo is an all-tube design completely free of semiconductors in its signal path. Its tube complement consists of the classic glassware beloved of audiophiles: four ECC83 and two ECC88 vacuum tubes. The use of these tubes will ensure that supplies of replacement tubes are always readily available – and experimentation is encouraged for those who love to fine-tune the sound of their systems by 'tube rolling.'

In the fully-balanced input stage, EAT uses 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 equalization, without any a 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.

Perfect Matching and Adjustability

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 types in six user-switchable steps from 47pf to 900pF. The loading resistance for moving-coil cartridges is continuously adjustable.

Quiet Operation is Ensured

Ensuring quiet operation is 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 tube phono preamplifier because the best way to shield a mains transformer from electromagnetic radiation of is to distance it from the electronics. Metal shielding alone cannot perform the task as well as a separate power supply. For the rectifying circuitry, E.A.T. fitted special diodes with noise suppressing resistors. Also employed are high-quality electrolytic capacitors, followed by a voltage regulator with capacitor multiplier. The power component is a FET transistor.

A Feast for the Eyes

A feast for the eyes, the handsomely styled E-Glo is housed in a beautiful 17.1” x 3.5” x 10.6” chassis with vacuum tubes peering through cleverly design heat sinks that recall the two spools of a reel-to-reel tape deck. Across the front section are rows of switches for instant access to all settings, there is no need to "get inside" to set the E-Glo for your cartridge of choice. E.A.T.'s E-Glo is a state-of-the-art phono stage able to extract the ultimate performance from any cartridge it asked to accommodate.

"How well does a product at any given price point reveal the music played through it? That’s where the E-Glo performs well beyond its price tag, and if you didn’t know better, you’d think this one has a five-figure price tag. Playing side by side up against some phono stages from more established models in the $10k – $13k range, the E-Glo holds its own on all fronts.

"So the seven thousand dollar question is, is it for you? That will depend on your budget and associated hardware. I suggest a trip to an EAT dealer and see if you love this one as much as I do. I bought the review sample and will be using it as a permanent reference component, so you’ll be hearing a lot more about the E-Glo as time goes on. It’s a perfect fit for my system."
