The most important toroidal transformer present in an influence amplifier promoting for £1500? Leema Acoustics, a Welsh hi-fi producer cofounded by two ex-BBC engineers, reckon it could possibly be of their new Graviton: Class A/B, 150wpc into 8 Ohms, 260wpc into 4 Ohms.
From the press launch: “The Graviton has an over-specified single transformer provide and 6 matched Toshiba output transistors per channel, permitting excessive instantaneous present supply for superior transient functionality and long-term reliability. Twin speaker binding posts are included to permit straightforward bi-wiring, plus line stage loop through-outputs for bi-amping.”
However the Graviton is just one half of this story. Each energy amplifier wants a pre-amplifier to offer supply choice and quantity attenuation. Becoming a member of the Graviton in Leema’s extra reasonably priced Quantum vary is the Neutron pre-amplifier that boasts 13 (13!) inputs: 4 single-ended RCA, balanced XLR; MM/MC phono stage; 3 x TOSLINK; 3 x coaxial and USB.
The phono stage is reportedly based mostly on Leema Acoustics’ proprietary design however the DAC comes from ESS Labs to assist PCM as much as 24bit/192kHz and the amount management from Burr-Brown.
On outputs, we word variable balanced XLR and single-ended RCA, fixed-level RCA; a pair of subwoofer outs and a devoted headphone amplifier that exits by way of the entrance panel’s 6.4mm socket.
Again to the press launch: “Quantum borrows closely from the corporate’s flagship Constellation sequence and has been repackaged so as to vastly enhance affordability. The casework is easier, single transformers change multi-transformers, and the board meeting has been expertly simplified with no lack of part high quality. Leema Acoustics famously manufactures its personal circuit boards at its UK manufacturing facility, giving unrivalled high quality at its value level. Nearly all of the PCB elements are shared with the Constellation sequence permitting economies of scale to straight profit the brand new Quantum vary.”
The Neutron pre-amplifier additionally sells for £1500 however for those who purchase the 2 collectively you may take £200 off the overall. Your alternative of silver or black.
