Blue Horizon PROFONO Phono Pre-Amplifier
Profono is designed and built to be a genuinely high-end phono preamplifier delivered at a highly competitive price point, able to compete with – and even outperform – models at twice the cost. Carefully selected premium-grade components and materials are used throughout – for example, the cheap ‘dip switches’ found in lesser phono stages are replaced by a series of shunt resistors to set cartridge impedance. This is a better quality solution than capacitance loading switches, which tend to be cheap and affect the purity of the signal, in addition to being an entrance point for RFI (Radio Frequency Interference).
Compact in size and sturdily built, Profono sports a cleverly designed all-aluminium case, with individual corner extrusions holding the aluminium panels together, ensuring a tight, rigid and reliable construction that is quick and efficient to manufacture. Casework of such quality is rare at this price point and serves to protect the internal components, reject sonically deleterious RFI and keep the unit solidly in position when heavy cables are connected.
To minimise noise and distortion, the Profono’s power supply unit (PSU) is housed separately and connected via a detachable cable. A switch on the Profono’s rear panel gives three settings for cartridge gain: moving coil low (50dB), moving coil high (61dB) and moving magnet (41dB). Offering two moving coil gain settings is unusual for a sub-£1,000 phono preamp and ensures optimal performance with an extensive range of phono cartridges. The net result is a high performance yet affordable phono preamplifier that delivers wide compatibility and class-leading sound quality in a simple, convenient package.
Design
Uniquely, the machined stainless steel outer casing of each spike shoe allows a spike loading of up to 100Kg. It is filled by a combination of specially chosen materials. This proprietary mixture of ingredients are at opposite ends of the elasticity spectrum. The differing resonant frequencies of these materials ensure that resonance is damped equally across the audio band, rather than simply delivering a tonal shift.
The combination of improved coupling and effective resonance control delivers clearly audible benefits, opening up the sound and improving definition from bass through to treble and an opening of the sound stage with greater micro dynamic information.
Specification:
- Fully adjustable/customised cartridge loading system
- Moving coil low, high settings and moving magnet
- Multi functional earth connection point
- Solid RFI resistant case, 170 x 80 x 50mm (L x W x H)
