Descriere Producator

Pass Labs este probabil cel mai nobil nume din industria amplificatoarelor, şi acest lucru i se datorează într-o proporţie covârşitoare celui care în urmă cu două decenii a înfiinţat compania. După 40 de ani de inovaţii şi realizări excepţionale, legendarul Nelson Pass rămâne în zilele noastre cel mai influent inginer din industria producătorilor de amplificatoare de înaltă fidelitate, fiind considerat un personaj aproape mitic de către comunitaţile de audiofili. Proprietar a şapte patente şi adevărat guru al entuziaştilor domeniului DIY, Nelson Pass este un adevărat părinte al industriei high-end, foarte mulţi dintre cei care în zilele noastre sunt ingineri de top ai concurenţei avându-l direct sau indirect ca mentor. Amplificatoarele PASS Labs au devenit pentru fanii mărcii, adevărate obiecte de cult, înglobând în ele tehnologii unice, patentate, şi sunt guvernate de cea mai pură filozofie a sunetului, un principiu ce stă la baza tuturor creaţiilor ce poartă semnătura lui Nelson Pass: “cel mai important lucru la un amplificator este calitatea sunetului pe care este capabil să-l imprime boxelor, cantitatea de emoţie pe care o induce ascultătorilor şi nu în ultimul rând, realismul şi naturaleţea pe care o poate imprima înregistrării”. Construite fără excepţie cu acest scop declarat, produsele PASS Labs sunt unanim recunoscute ca fiind cele mai bune electronice hi-fi din lume, fiind dorite, adulate şi respectate de către toţi iubitorii de muzică de calitate care au avut ocazia să le asculte măcar o dată.

XP-20

With a separate power supply electrically isolating delicate analogue signals in the preamplifier, this cosmetically-matched dual-chassis reference line-stage preamplifier offers significant gains in detail retrieval over the XP-10 without loss of musical soul. How does this translate into the sonic fidelity you really care about? Instruments and voice are presented in a more refined soundstage, and with better spectral balance. Fine nuances and details, which frequently go un-noticed, now become beautifully apparent -- even in loud and highly complex musical passages.

"The XP-20 is truly an amazing product, and in my opinion, it’s one of the finest preamplifiers in the world."

Cyrus PRE₂ DAC QXR: Preamplificator cu DAC inclus

Cyrus PRE₂ DAC QXR: Preamplificator cu DAC inclus
Moving to a separate pre-amplifier and power amplifier offers another level of refinement to enthusiasts looking to upgrade from an integrated amplifier, or those looking to build a reference-grade system. A two-box set up enables the pre and power amplifiers to be run by separate power supplies resulting in a cleaner signal as the inductive effects of the large currents in the power amplifier are isolated from the sensitive components of the pre-amplifier.

The effect is astonishing. The experience is cleaner, more powerful and fantastically engaging. You will rediscover your collection with a whole new perspective on the performance. The Pre2 DAC is our first step on the pre-amplifier ladder.

QXR VERSION
The Pre2DAC QXR is a standard Pre2DAC with the new QXR digital card pre-installed. This new card improves the sound quality across all the digital inputs, increasing the possible input resolution to 32bit/ 768k (DSD 512) through the USB connection. Using a new ESS-based DAC, we have also introduced a new ‘reclocking’ process across all the digital inputs, to reduce jitter and lower the noise floor, as well as allowing a much shallower filter slope than ever before, virtually eliminating phase interference in the audible band (an approach only previously possible with noisy FPGA DAC solutions).
[expand title="Mai multe detalii..."]
The Pre₂ DAC offers complete control of your analogue and digital sources. With perfect balance, it delivers a superlative performance, although can easily be upgraded through the addition of a PSX R2 and QX module.
The Pre2 DAC separates the pre amp into its own chassis and provides a dedicated power supply which means the pre amp can resolve more detail. Complete with a built-in DAC, the pre amp is compatible with a very wide range of sources such as CD players, streamers or your TV digital audio out.
The Pre2 DAC offers a sonic step up in performance from our integrated amplifiers. This is achieved because the pre amplifier circuitry has its own power supply. The internal power supply provides isolation from the demands of other system elements, making available an additional level of dynamics and resolution. The digital section also sounds better for the same reasons, especially when used with the optional Qx card, the audio quality rises further still.
If a PSX R2 is connected, owners will hear a large jump in performance as the PSX R2 feeds the pre amp with a highly regulated and super smooth DC feed. The sonic uplift from the PSX R2 means the close tolerance components in the pre amp can be fully appreciated as they now benefit from the smoother supply.
The Pre2 DAC includes a carefully designed top quality digital section built into the pre amplifier with a Burr Brown 24-bit/192k DAC and a carefully designed power supply. With 5 digital inputs that enable the amplifier to connect and clearly improve the sound of connected digital sources including; your computer, DVD player, TV and many other digital sources.
In the QXR version, in which we use a new ESS-based DAC, as well as allowing input resolutions up to 32bit/ 768k, we have also introduced a new ‘reclocking’ process across all the digital inputs. This substantially reduces jitter and lowers the noise floor, as well as allowing a much shallower filter slope than ever before. This process virtually eliminates phase interference in the audible band (an approach only previously possible with noisy FPGA DAC solutions).
The Pre2 DAC is designed to be partnered with one of our matching power amplifiers such as the X Power, Stereo 200 or Mono X 300 Signature. Build your system with a CD i or CD t and a Stream X Signature or Stream Xa for an exceptional music experience. Add a dedicated power supply such as the PSX R2 to further enhance the pre amp’s resolution.[/expand]

Descriere DAC 215

UNIVERSAL HIGH RESOLUTION DAC, PRE-AMPLIFIER, HEADPHONE AMPLIFIER

The digital revolution has made music easily accessible. Thanks to the convenience and impressive sound quality of computer sourced digital music files, many audiophiles consider their personal computer or laptop as their primary audio source. Connected to a computer the DA215 will process audio data of extremely high resolution and the playback quality will be defined mainly by the data itself.

The heart of the DA215 is an excellent D/A converter with multiple S/PDIF inputs, PCM, and DSD capabilities using the ES9018 Reference 32-bit DAC in quad-mono configuration, 8 mono to 2 stereo configuration. Combining four in-phase and four opposite-phase converters per channel, the statistical properties of the signals are taken to advantage; the signal power of the phases correlate and add-up in constructive addition, whereas the noise power of the phases are de-correlated, improving the signal to noise ratio of the resulting analog waveform.

The class-A buffering technology of the analog filtering sections is borrowed from the highly acclaimed Copland CD-players and composed by discrete transistors producing a stunning sound quality with an unconstrained mobility and acceleration.

The DAC 215 incorporates an asynchronous USB input, tree S/PDIF digital inputs, an analog input, two analogue outputs (fixed and variable) and a complete pre-amplifier with analog volume control and front panel headphone output featuring vacuum tube gain stages.

"There’s much to like about this Copland. A pleasure to use and listen to."
"...the Copland DAC215 is an ideal travelling companion in your trek through your musical canon. Recommended."
"The DAC215 is a very special addition to the Copland family, filling a gap in today's hifi bucket list...Highly recommended!"
"A sumptuous valve headphone amp with oodles of power and a pleasant dash of warmth."
"Here is an excellent USB DAC/headphone amp that can veryhappily serve as a main systempreamplifier too...It provides truly enjoyable,satisfying headphone listening from digital sources, especially via USB but also via its S/PDIF input. It’s nice to use and the attractive retro look is a bonus. Great value."
