The L2 DAC is our latest, statement-level d-a converter module that allows music to flow in an effortless manner that mirrors true analog playback with its highly resolving and dynamic, yet non-fatiguing sound signature. No matter if you are playing PCM files from 16-bit/44.1kHz to 32-bit/768kHz or DSD files from DSD64 to DSD512, you will become captivated listening with Vinnie Rossi’s approach to digital playback.

L2 DAC Features

• Bit-perfect playback at sampling rates up to PCM 768kHz (16, 24, or 32 bit compatible), as well up to DSD512. Sample rates are viewable from front panel display.
• Dual-mono design, with one flagship AKM AK4497EQ d/a chip per channel.
• Fully discrete, pure Class-A JFET analog outputs stage design with cascode constant-current source biasing (no opamps).
• On-board FPGA buffer and femto-reclocking circuitry negates effects of jitter. Isolated input stages.
• ‘NOS’ (non-oversampling) filter mode with digital filter bypass, as well as a Minimal Phase digital filter mode (selected via the “FILTER” button on the L2 Remote).
• Absolute polarity ‘normal’ / Absolute polarity ‘inverted’ modes (selected via the “PHASE” button on the L2 Remote).
• Belleson Super-regulated voltage feed to numerous ultra-low noise, linear voltage regulators used throughout (for both digital and analog sections).
• “Silent” mute ‘reed relays’ (*barely* an audible click from the board when changing tracks of a different sample rate).
• Inputs: 1 USB, 1 Coax (75-ohm BNC, with included RCA adapter) and 1 TOSLINK (optical).
• Connect up to three devices and switch between them via L2 front panel or the remote handset.

L2 Phono is our new, statement-level phonostage that we designed in collaboration with Brian Lowe of Belleson (patent owner of the Belleson super-regulators used throughout our L2 products). It provides a highly resolving, dynamic, and entirely natural sound signature that will bring you a whole new level of enjoyment from your LP collection.

L2 Phonostage Features

• Inputs: 1 set of Moving Magnet (MM), 2 sets of Moving Coil (MC)
• Built-in, on the fly MC remote adjustable cartridge loading (10 – 1000 ohms). Cartridge load setting viewable from L2 front panel display
• Adjustable gain jumpers for MM and MC inputs
• Belleson Super-Regulated split-supply voltage rails
• Four low-noise and low distortion gain stages. Each stage has a nominal gain of 20dB, resulting in higher bandwidth per stage and lower phase shift across the audio band
• Low output impedance design
• DC coupled from input to output (no dc blocking capacitors added in series to the signal path)
• DC Servo keeps output offset negligible
• Design optimization for lowest value thin-film resistors, resulting in the least possible noise
• High accuracy resistors and capacitors used throughout
• 4-layer PCB with separate ground planes for analog and digital (control circuitry)
• Cardas Audio input jacks
• Connect up to three tone arms and switch between them via L2 front panel or the remote handset
