BRAMA Preamplifier

The heart and soul of your system.

 

At the heart of the Brama Preamplifier lies Vinnie Rossi’s finest 300B linestage, featuring a matched pair of premium Western Electric WE300B triodes. Operating in pure Class A, these legendary triodes deliver an immersive listening experience with unmatched realism and tonality.

The Brama Preamplifier’s fully balanced input and output stages ensure exceptional noise rejection and signal transfer between your source components and power amplifiers. A notable design feature is the direct mounting of the entire preamplifier’s dual-mono circuitry, including the 300B triodes, to the rear panel jacks. This unique approach minimizes the input-to-output audio signal path to only a few centimeters, effectively reducing signal degradation and preserving the purity of the audio signal.

Pure analog emotion.

 

The front panel of the Brama Preamplifier presents a clean layout, luxurious feel, and timeless design, purposefully omitting digital displays and visual clutter.

Its bespoke analog VU gauge features a precision air core movement, responsive driver circuitry, and a machined aluminum hand. Sapphire glass and a highly-polished stainless bezel seamlessly integrate the gauge into the front panel.

Solid aluminum knobs are attached to Swiss-made, precision-stepped rotary switches, providing manual control with an incredibly satisfying feel.

Effortless command of your listening experience.

 

The Brama Remote sets a new standard in the audio industry. Its intuitive menu structure, high-resolution display, and tactile push buttons provide seamless control over your listening experience.

Effortlessly adjust volume, gain, balance, and independently save settings for the five inputs. Bluetooth communication with your Brama Preamplifier eliminates line-of-sight or range issues, while USB-C connectivity ensures easy battery recharging and firmware updates.

Crafted from a solid block of aluminum, the Brama Remote features a sapphire glass display area for remarkable scratch resistance and clarity.

Powering your passion.

 

The Brama Preamplifier boasts a custom switch-mode power supply with linear, Belleson super-regulated outputs, ensuring exceptionally low output noise and impedance across the audio spectrum for pristine performance. Its high-speed operation and low magnetic losses guarantee an ultra-fast transient response, surpassing conventional linear supply designs and delivering superior pace, rhythm, and timing in music reproduction.


The power supply features independent outputs for the positive and negative preamplifier voltage rails, 300B cathode heating, and front panel control circuitry. This design minimizes crosstalk and interference, enhancing overall performance. Regardless of AC mains quality, the power supply maintains superior regulation and stability. Housed in a fully enclosed compartment precision-machined into Brama’s solid aluminum body, it is fully grounded and isolated from the audio circuitry, operating like a highly-responsive, well-tuned engine.

Simplicity – the ultimate sophistication.

 

Uncommon even among cost-no-object components, the main body of the Brama Preamplifier is precision-machined from a solid block of aluminum. This construction offers exceptional resonance control, complete shielding against electromagnetic interference (EMI), and ensures superior heat dissipation, thereby guaranteeing the long-term reliability of its internal components.

From an industrial design perspective, the seamless construction enhances the preamplifier’s aesthetic appeal for audiophiles who value sophistication and elegance.
