Leema Acoustics adds Neutron preamp and Graviton power amp to Quantum range
Borrowing heavily from the company’s flagship Constellation series and repackaged in order to improve affordability, the amps display simpler casework while single transformers replace multi-transformers, and the board assembly has been simplified with what Leema claims is no loss of component quality.
The Neutron DAC/preamp offers a high-quality switchable MM/MC phono stage, based on Leema Acoustics’ proprietary design. The preamp also benefits from an advanced asynchronous ESS 24-bit/192kHz USB DAC, a dedicated headphone amplifier, plus a high-end Burr-Brown analogue volume control.
Highly versatile, with wide-ranging connectivity, the Neutron includes 13 inputs: four RCA and one XLR; one MM/MC phono stage; three optical; three coaxial and one USB. Outputs include: fixed-level record; two dedicated subwoofers; a dedicated headphone amplifier, plus 12V trigger.
The Graviton stereo power amp benefits from what the company claims: “could be the biggest toroidal power supply ever seen at its price point!” A Class A/B design, offering a claimed 150W per channel into 8ohm and 260W into 4, the Graviton’s high-current topology deploys six output transistors per channel.
The Graviton has an over-specified single transformer supply and six matched Toshiba output transistors per channel, “allowing high instantaneous current delivery for superior transient capability and long-term reliability.” Dual speaker binding posts are included for bi-wiring, plus line-level loop-through outputs for bi-amping.
All Quantum-range devices are designed in UK-made casework available in brushed black or silver finishes, with solid aluminium precision-machined front panels and control dials. The Neutron is priced at £1,500, the Graviton is also £1,500, and bought together the package is £2,800.
