European Audio Team (EAT) E-Glo CB Phono Stage

European Audio Team (EAT) E-Glo CB Phono Stage

E-Glo CB is a high-end, balanced and fully discrete tube-hybrid phono stage. It extends the design philosophy of EAT's flagship E-Glo F B — the first all-tube, fully balanced phono stage on the market — to a more accessible price point, alongside its sibling the E-Glo SB. E-Glo CB shares many high-end components and the same high-quality polypropylene film capacitors in its gain and RIAA stages, delivering much of the effortless musicality, tonal richness, and dynamic expressiveness of a meticulously executed tube design. As an authorized EAT dealer in Buffalo, NY, Vinyl Sound can help you match this phono stage to your turntable and cartridge.

Hybrid Tube Topology

The balanced gain stage uses three discrete semiconductor operational amplifiers to process the + and - signal paths symmetrically before combining them into the first of two discrete RIAA equalisation stages, optimizing signal-to-noise ratio ahead of the EQ section. The second stage is a single-ended hybrid design combining two ECC83S triodes with one transistor, unlike the fully tube-based second stage on the E-Glo SB — this stage includes the second RIAA EQ and the subsonic filter. The output stage uses a dual discrete semiconductor op-amp to convert the unbalanced internal signal to balanced, maintaining low output impedance and low DC offset via dedicated DC servo circuits.

MC and Balanced MM Cartridge Compatibility

Connecting your turntable to the XLR input takes advantage of the balanced signal path, but requires an MC cartridge or a specially modified balanced-compatible MM cartridge — a typical unbalanced MM cartridge will show increased noise in the right channel if used on a balanced input, due to how its internal generator is grounded. Any MM cartridge, balanced or unbalanced, can be used on the standard single-ended RCA inputs. Ask Vinyl Sound if you're unsure which input matches your cartridge.

Discrete Circuitry

E-Glo CB uses fully discrete audio circuitry throughout, rather than integrated IC op-amps. EAT states that, based on extensive listening tests, even the best IC op-amps don't achieve the same neutral, natural, dynamic sound as a discrete design — a standard IC-based phono preamp uses a few tens or hundreds of components, while a fully discrete design like this uses hundreds or thousands.

External Power Supply

E-Glo CB is powered by an external advanced power supply, keeping electromagnetic-field-radiating components away from the sensitive phono circuitry. For further improvement, the separately sold EAT LPS 2 linear power supply upgrade uses a low-core-saturation, vacuum-impregnated transformer with shielding between windings and a DC-blocker, in its own matching enclosure — bringing E-Glo CB's performance a step closer to the flagship E-Glo F B, which ships with its own LPS by default. The LPS 2 also includes a second output to power a compatible EAT turntable.

Cartridge Loading Options

Gain ranges from 40dB up to 70dB (with a +6dB option via the XLR outputs), handled cleanly thanks to the fully balanced design. Two load impedance ranges are available — "low" for standard MC cartridges, and an unusual "high" setting that lets you fine-tune MM cartridge loading beyond the typical fixed 47kΩ found on most phono stages. RCA and XLR outputs can be used simultaneously for extra flexibility when connecting to multiple systems.

Frequently Asked Questions

Can I use my existing MM cartridge on the balanced XLR input?
Only if it's a specially modified balanced-compatible MM cartridge. Standard unbalanced MM cartridges will show increased noise on the right channel if used on the XLR input — use the RCA inputs instead, which work with any MM cartridge.

Can I connect two turntables at once?
Yes, two turntables can be connected simultaneously, with each input's settings stored in memory.

Is there an upgrade path for the power supply?
Yes, the separately sold EAT LPS 2 linear power supply improves noise performance further and also powers a compatible EAT turntable from its second output.

How does this compare to the E-Glo SB and E-Glo F B?
E-Glo SB steps up to a fully tube-based second amplifier stage (no transistor) and higher-grade polypropylene capacitors. E-Glo CB uses a hybrid tube-transistor second stage. E-Glo F B remains the flagship, shipping with its own dedicated LPS power supply as standard.
