Leema Acoustics has launched the Libra DAC/preamp, an “astonishingly featured- packed high-resolution digital hub, combining highly advanced digital technologies with an incredible complement of connectivity options.”
The Libra is the latest addition to Leema Acoustics’ flagship Constellation series and has the same precision-machined casework as the award-winning Tucana amp and Antila CD player.
Designed and built by Lee Taylor and Mallory Nicholls (Leema), Libra’s simple-yet- elegant looks conceal a “staggering array of class-leading technologies”. The new Libra crystallises Leema’s decades of experience in digital audio for professional studios worldwide.
The high-resolution Libra DSD DAC has been designed for today’s (and tomorrow’s) HD audio world and is said to be fully future-proofed. The Libra offers extreme high- resolution playback including: DSD 64; DSD 128, DXD and 384kHz PCM via USB (and Libra’s I2S inputs). DSD64 is also supported via all S/PDIF inputs (coaxial and optical) and AES/EBU inputs.
The new high-resolution DAC/preamp contains Leema Acoustics’ new fully balanced Quattro Infinity dual-mono DAC modules which are field-replaceable; should conversion technology improve in the future, the modules can be upgraded. The advanced Quattro Infinity modules also feature user-selectable output filters, for maximum flexibility with higher sample-rate sources.
The Libra boasts loads of connectivity options plus three coaxial and three optical inputs, capable of accepting high-resolution 24-bit/192kHz audio. For high-end partnering equipment, the Libra also offers some more esoteric options, including two I2S inputs via RJ45 connectors. With fully programmable pin-allocation on one of these inputs in software, any high-end source with an I2S interface can easily be accommodated. Source components with professional standard AES/EBU outputs can also be connected: the Libra offers two input connections available via industry standard XLR connectors.
Leema’s M1 USB module provides a connection for computer audio replay from both Windows (driver software included), Macintosh and Linux machines. This interface is fully asynchronous, allowing the Libra to precisely regulate the data rate coming from the computer and deliver “incredibly low jitter levels”.
Libra offers three separate analogue inputs, each of which can be individually configured as unbalanced, via RCA Cinch connectors, or fully balanced via XLR connectors. The entire signal path, both digital and analogue, is fully balanced from the digital data stream, to the balanced analogue outputs.
The Libra is able to operate either as a conventional audio component with fixed output level, or as a high-end pre-amplifier with full analogue volume control on-board. Outputs are provided via unbalanced RCA/Cinch connectors and balanced XLR connectors. Libra is also a full LIPS controller (see below) and can control Leema Acoustics’ range of power amplifiers directly.
For added flexibility in the digital age, the Libra also has an optional Bluetooth interface and a headphone amplifier.
LIPS is an acronym of Leema Intelligent Protocol System. It is a communication bus that enables Leema Acoustics components to communicate with other units in the range. The communication enables simple control of power on/off from one unit, right up to the control of all functions in a Leema Acoustics system, comprising up to 15 individual components.
The Libra DAC/preamp is priced at £5,995 and is available now.

It’s an integrated amplifier with an open chassis design and is intended to be a step up to the existing VSi60 integrated amplifier which will continue to be manufactured and sold.
The new amplifier has new look case-work, a natural anodised top plate and an LCD display showing input selection, volume, individual valve bias etc.
The VSi75 delivers 75W per channel using four KT120 output valves and two 6H30 driver valves. Wide bandwidth output transformers are used along with proprietary coupling caps matching those used in the Reference 75 amplifier.
The unit comes with a metal cased remote handset
Audio Research said “The resulting sound from these cumulative improvements is striking, with tremendous resolution of detail, silky and extended highs, surprising weight and authority, and the ability to develop an immense sound stage. The VSi75 sounds very much like the amp from which it borrows, the REF75, with an immediacy, delicacy and focus that are captivating.”
Combining valve rectification with only two audio valves the Icon Audio MB30SE has been designed with purist simplicity in mind. With an output of up to 27 watts the MB30SE is versatile and capable of high volume levels with medium to high sensitivity loudspeakers.
Using the new KT 120 output valve the MB30SE delivers a good deal more power than triodes such as the 300B and with Icon Audio’s Low Distortion Tertiary transformer on-board the KT120 can deliver a wide bandwidth.
Using high sensitivity loudspeakers the 16 watts produced in triode mode will produce realistic volume levels. However many modern speakers sacrifice efficiency for size and in such cases the MB30SE can be switched to ultralinear mode to deliver 27 watts. Adjustable input sensitivity adds to the flexibility enabling use with either passive or active preamplifiers.
The front panel mounted bias meter allows easy checking and adjustment of the amplifier to give its best performance and also gives an indication of output power.
Every amplifier is finished and tested by Icon Audio’s team of engineers in Leicester, UK.

- Thin-film switched-resistor ladder network for controlling volume – only a single resistor in the signal path at any volume setting
- Individually adjustable volume on each input for precise level matching of all sources
- A pair of V3 amplifier modules
- Cross-Matrix Array (CMA) capacitor module
The NuForce IA-18 is available worldwide for a suggested retail price of US$3500 and shipping immediately.
Hi-Fi distributor Sound Fowndations has announced the addition of the CANOR TP134 valve amplifier to its portfolio of high quality audio components.
The CANOR TP134 is a high quality stereo integrated amplifier that uses EL34 output valves to generate 35 watts per channel operating in pure class A up to 10 watts per channel. The circuit boards feature patented CMT ™ (Canor Milling Technology) which means that areas of the circuit board are precisely removed to give the circuit similar electrical characteristics to one direct wired with air dielectric cables.
The TP134 features a high quality relay attenuator volume control which the company say provides a “more direct signal path with fewer contacts than typical volume controls leading to precise control and higher sonic performance”.
All control electronics, such as input switching and volume adjustment, are fed from a separate section of the power transformer and the control circuitry is only active when being used which Canor says avoids degradation of the sound quality of the amplifier.
Further the Canor TP134 boasts double copper foil shielding between the mains transformer to prevent mains noise from affecting the performance, a high capacitance anode power supply filtration providing “tight and accurate bass performance”, audiophile quality polypropylene capacitors in audio signal paths, custom designed bifilar wound output transformers “providing maximum power evenly across the entire bandwidth.
For the terminally lazy the TP134 is supplied with a remote control – Hifi Pig REALLY wants a remote control!

Audion have today announced the release of their latest product Audion Select, a passive pre-amplifier.
“The name “Audion Select” has been given as it’s mainly an input selector and in the double entendre stakes its also quite a select product.” Said Graeme Holland of Audion.
The basic Audion Select is a passive pre-amplifier with 5 line inputs, 2 line outputs and an unattenuated tape loop. Volume control is by an Alps pot fitted and with ground loop lift switch and hard wired.
The chassis is designed to match the rest of the Audion range in looks and sound quality, and having the same size and shape will fit in with other Audion equipment when on your rack.
The retail price for the standard 5 channel model is anticipated at £475 and the Audio Slelect pre-amplifiers are available now and will be with our distributor (Deco Audio in the UK) in approx 1 weeks time.
There will be versions with 48way stepped attenuators, and / or silver wire, and possibly transformer volume control.
In future Audion will be developing a transistorized mm/mc phono stage (aimed at the Revolver market which Audion now owns), a select passive pre with balanced in/outs and even a headphone amp (valve) in the chassis.
