E.A.T. E-Glo C B Phono-Preamplifier

E-Glo CB: Symmetrical high-end tube phono preamplifier with discrete circuitry

With the EAT E-Glo CB, uncompromising high-end technology from the flagship E-Glo FB model enters a significantly more accessible price range. The "B" in the name stands for Balanced – and it is precisely this consistently symmetrical signal processing that makes the phono preamplifier an exceptional device for discerning vinyl enthusiasts. Handcrafted in Europe, this compact unit combines the musical warmth of selected tubes with the precision of modern, fully discrete circuitry.

Fully symmetrical signal processing for maximum quietness and dynamics

The E-Glo CB operates fully balanced right from the first amplifier stage. Both MC cartridges and specially modified balanced MM cartridges benefit from exceptionally low background noise via the new balanced XLR inputs. Of course, classic RCA inputs are also available for conventional MM and MC cartridges.

Hybrid tube topology without compromise

The heart of the sonic character is the sophisticated hybrid tube topology, which completely dispenses with integrated operational amplifiers (IC-OpAmps):

Discrete input stage: Three discrete semiconductor operational amplifiers provide low-noise pre-amplification and optimally prepare the signal for the first of the two split passive/active RIAA equalization stages.

Tube sound stage: Two ECC83S triodes together with a transistor form the second amplifier stage including second RIAA equalization and switchable subsonic filter.

Symmetrical output stage: A dual discrete semiconductor operational amplifier converts the signal back into a symmetrical output signal, while special DC servo circuits reduce the DC offset to a minimum.

High-quality, semi-crystalline hydrocarbon polypropylene film capacitors in the amplifier and RIAA stages guarantee maximum temperature and frequency stability with extremely low loss. The result is effortless musicality, exceptional naturalness, and vibrant dynamics.

Flexibility for two turntables and any setup

Comfort and adaptability are paramount with the E-Glo CB. Two turntables can be connected simultaneously and individually configured – all settings are reliably saved. Fine-tuning is possible without opening the housing, thanks to the clearly arranged toggle switches on the front panel and the control panel on the top.

Gain from 40 dB to 70 dB: Thanks to its fully symmetrical design, the preamplifier effortlessly handles even extremely quiet MC systems and seamlessly adjusts the level to digital sources such as streamers or CD players.

Finely adjustable termination impedance: In addition to the common "Low" values for MC cartridges, the "High" range offers a rare fine-tuning option for MM systems, deviating from the rigid 47kOhm standard.

Parallel outputs: RCA and XLR outputs can be used simultaneously to drive multiple amplifiers or recording systems.

Off-site power supply and upgrade potential

To protect sensitive audio signals from electromagnetic interference, the E-Glo CB uses an external switching power supply with a standby power consumption of less than 0.5 watts. For audiophiles who want to exploit the preamp's full potential, the optional EAT LPS 2 linear power supply is available. Equipped with a vacuum-impregnated transformer, winding shielding, and a DC blocker, it delivers ultra-pure power – and also supplies a compatible EAT turntable via a second output.

Elegant all-aluminum housing with a unique look

Visually, the solid aluminum housing – available in silver or black – adds a stylish touch to the listening room. The two ECC83S tubes shimmer through the viewing window; their LED backlighting can be adjusted in color and dimmed.
