OSNOVNE TEHNIČKE ZNAČAJKE

L2i (Linestage)
Vinnie Rossi’s latest Class-A, ultra wide bandwidth directly heated triode (DHT) preamplifier design, compatible with: 2A3, 45, 300B, PX4, 101D, 205D, and SV811 DHT families with one-switch filament voltage selection
Dual-mono layout using multiple patented Belleson super regulators for ultra-quiet linear voltage regulation of the triodes, and the (optional) L2 DAC and L2 Phonostage modules
Discrete, 64-step resistor ladder volume control using Pickering England silent signal relays
True active balanced (XLR) and single-ended (RCA) line level inputs and preamplifier outputs
Internal “DHT bypass mode” switches (replaces DHT stage with a Class-A JFET stage)
Yamamoto solid Teflon UX-4 tube sockets
Mesh tube covers for added noise shielding and tube protection
Included tubes: EH300B Gold-Grid (matched pair) Full-function aluminum remote control handset

L2i-(Power output stage)

Wide-bandwidth, purist Class AB MOSFET topology (only one pair of output devices)
True dual-mono power supply with custom-wound toroidal power supply transformers
WBT NextGen 0703cu Speaker Binding Posts
Speaker outputs can be switched on/off via the front panel
Power output, no matter the DHT, is a flexible 100Wpc into 8 ohms and 170Wpc into 4 ohms. Voltage gain is about 32dB with DHT tubes and 24dB in DHT-bypass mode. The integratedweighs a hefty 50 pounds and has a quite reasonable footprint of 17¼” wide and 14½” deep.

Solid, precision CNC machined aluminum chassis and “bank vault,” ball bearing control knobs
Solid, precision CNC machined aluminum isolation base with Stillpoints ULTRA MINI feet
Designed and manufactured by Vinnie Rossi in the USA

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
