PS AUDIO BHK Signature Preamplifier
Preamps can make or break a system; holding back rich details buried in the music. They are the critical link between sources and power amplifiers. Precious few of them–only a handful really–uncover, preserve and amplify the rich bloom of music. The BHK Signature Preamplifier is one of the rare few that brings out the magic.
Preamplifiers are the heart of any high-end music system controlling input selection, the critical first amplification stage, volume and balance functions, and the all important electrical isolation between sources and power amplifiers. Place the BHK Signature Preamplifier between your musical sources, such as a phono preamp, DAC, tuner or auxiliary source–and your power amplifier–and magic happens. Suddenly you are enveloped in a wealth of musicality you’ve not yet experienced: deeper, wider sound staging, improved separation of instruments and voices, Subterranean bass, extended highs, and an openness you have yet to experience without this instrument in the system.
Description

ARCAM CDS50 CD/SACD Network Player
CDS50
Our most advanced cd, digital audio and network streaming player yet
In a sense, digital audio doesn’t exist. You’d have to be a particularly dull superhero to possess ears that can decode the millions of 1’s and 0’s that make up your CD collection or iTunes library. Whatever the source – be it a laptop, CD player, smartphone, USB stick – the result is just a vibration in your speakers. In other words, it all winds up analogue in the end.
Arguably, when playing from a digital format, the most vital component is the DAC, or Digital to Analogue Converter. We’ll spare you the bulk of the science, but this is what translates that otherwise lifeless binary code into audible sound energy. Bit-depth, meanwhile, is a key measure of audio quality.
So, if you’re listening to a 24-bit WAV copy of your favourite album through a DAC that only converts to 16-bit, there’s a good chunk of detail going to waste right there. That’s why we’ve included 32-bit DACs on the entire HDA range – the most commonly used bit-depth in digital recording – so you’re guaranteed the full aural picture of whatever the artist intended.

REX 3 DAC
The BAT second-generation SuperPak is now standard
REX 3 now incorporates BAT’s second-generation SuperPak as standard. The SuperPak assembly features the largest energy storage ever offered by BAT in a preamp or source component. One must admire the SuperPak in BAT’s reference VK-655SE solid-state power amplifier to find a SuperPak assembly of comparable energy storage. REX 3 DAC’s SuperPak dramatically adds to the dynamic performance of the component by extending the bass and offering greater midrange authority.

LUXMAN PD-171A
Allow the musical character within the groove to truly breathe
PD-171 has been a highly regarded analogue player in the market due to its ability to convey the sense of musical depth and feeling of vinyl records. There are two new revisions, an armless type, the PD-171AL, and the PD-171A, with a universal tone arm, adjustable to the users requirements and systems. At the heart of these models is a newly developed, high output power supply circuit and an AC synchronous motor. We have incorporated ideas developed for our audio amplifiers and have adopted a belt drive system which rotates a high inertia, heavyweight turntable. A high quality hairline finished aluminum upper surface blends beautifully with the wooden base cabinet to conceal the robust and accurate machinery within, developing a warmer and softer personality with whom the listener may spend many hours of enjoyment, expressing the true personality of analogue recordings.

LUXMAN DA-150
Desktop revolution – a new definition of D/A converter
The DA-150 is a state of the art, compact, USB D/A converter built upon the same principle as its predecessor, the DA-100, that is to construct a simple PC audio environment to offer high quality sound in a small footprint. Desktop usability and high sound quality co-exist perfectly within the design of the DA-150 with features such as compatibility with USBs inputting PCM 192 kHz/32 bits and DSD 5.64 MHz (like the upper model DA-250), a headphone amplifier circuit with remarkably improved drive force and the addition of the LECUA* computerized attenuator as standard. As a digital interface to connect with various devices to reproduce high-resolution sound sources, the DA-150 raises the benchmark for compact D/A converters.
