Mark Levinson will introduce two new integrated amplifiers early next year. The No.5802 features an all-digital input set, while the 5805 adds analogue inputs and an integrated MM/MC phono stage.
The No.5802 features six digital inputs, comprising AES/EBU, coaxial RCA, Toslink optical and USB 2.0 facilities, as well as a Bluetooth interface that’s apt-X compliant. The amp’s digital heart is Levinson’s Precision Link II DAC, utilising the latest ESS Sabre 32-bit DAC chipset.
The DAC section will play back PCM files up to 192 kHz/32-bit resolution and is also DSD 5.6-compliant. In addition, the DAC can decode and render MQA-encoded files.
By comparison, the No.5805’s digital input complement is reduced to four, still spanning AES/EBU, coaxial, Toslink optical and USB. However, it gains three analogue input sets (one balanced XLR, two single-ended RCA) as well as a MM/MC phono input.
The No.5805’s pre-amp section is a fully discrete, direct-coupled design that uses a single gain stage linked to a digitally-controlled resistor network for volume control. Each analogue input set has its own signal-switching relays.
The phono stage is derived from the No.500 phono stage, but features a mix of discrete components and low-noise ICs to save cost. The phono stage is MM and MC compliant, and offers variable gain and loading settings for optimum cartridge matching.
Both the No.5802 and No.5805 use the same power amplifier section. It’s a Class AB design that employs a generous 500VA toroidal power transformer with individual secondary windings for the left and right channels.
The output stage uses a pair of high-speed driver transistors operating in Class A, and six 15A output transistors. Power output is rated at 125 watts/channel into 8 ohms, increasing to 250 watts/channel into 4 ohms. There’s a separate Class A headphone amp, too.
The two new amplifiers are set to go on sale in the US and Europe in the first quarter next year. South African availability should be soon thereafter.
