Descrizione

Cyrus Stream Xa è uno streamer musicale HiRes sviluppato sull’esclusivo e proprietario HD streaming engine che permette di decodificare e quindi riprodurre la musica con lo standard di qualità più elevato : 24 bit/192 KHz.

Lo Stream Xa riproduce la tua musica preferita da una varietà di fonti come la tua libreria di file, servizi di streaming di alto livello come Tidal o qualunque internet radio. A partire da questi servizi, e quindi dai loro dati digitali, un motore hardware e software proprietario Cyrus trasforma i dati in ingresso in illimitate ore di godimento musicale. Grazie alla assoluta comprensione delle logiche di conversione di dati digitali in segnali analogico, Cyrus raggiunge con questi streamer una performance allo Stato dell’arte. Ogni formato digitale viene gestito al meglio ed il risultato finale è straordinario. Devi solo sederti e controllare il sistema con la comoda App gratuita ‘Cadence’ per iOS o per Android.

Che la connessione sia Wi-Fi e cablata Ethernet l’integrazione con la tua rete sarà immediata e robusta. Hai altre fondi da cui ascoltare la musica? Nessun problema, ci sono ben 5 ingressi digital e uscite analogiche fisse.Sei soddisfatto ma vuoi ancora di più? Con il modulo opzionale sterno PSX R2, grazie alla porta dedicata, puoi fare un immediato upgrade di livello al tuo sistema ed esaltare le già incredibili prestazioni audio di Cyrus Stream Xa.

Servizi di streaming come Tidal forniscono una pratica e accessibile via di accesso a decine di milioni di brani ed offrono una superba qualità audio. Ben lungi dall’essere servizi giusto per ascoltare la musica in viaggio con il telefonino, ormai questi servizi garantiscono una qualità di streaming davvero elevata e sono considerati fonti di qualità audiofila. Le piattaforme di streaming sono oggi i riferimenti assoluti ed i dominatori attuali e futuri nel panorama della musica e della fruizione dell’esperienza  musicale.

Cyrus Stream Xa assolve a due funzioni principali. La prima è quella di tradurre la moltitudine di formati dei file musicali nella più pura forma di audio digitale : il formato lineare PCM. Parte integrante di questa “traduzione” da parte dello Stream Xa consiste nel re-clocking dei dati al fine di eliminate i ‘jitter’e la distortion temporale. La seconda funzione consiste nella conversione del flusso digitale in una forma analogica che possa essere inviata ad un amplificatore. Dotato di uscite sia digitali che analogiche, di ingressi Wi-Fi che Ethernet, di una porta USB asincrona, lo Stream Xa è uno streamer davvero completo e versatile.

I circuiti di Stream Xa sono stati disegnati in due sezioni completamente separate permettendo al prodotto di essere aggiornato e di ricevere un possibile importante upgrade attraverso il collegamento con il modulo di alimentazione esterna PSX R2. Questo collegamento isola il DAC migliorando il timing ed elimina l’intermodulazione che può impattare negativamente sul delicato segnale analogico di uscita. Anche se non necessario per ottenere prestazioni straordinarie, l’utilizzo di PSX R2 da una marcia in più alla vettura che ogni audiofilo vuole costruire.

Perché Cyrus

    Cyrus è un'azienda specializzata per l'audio costruita attorno al suo team di Ricerca a Sviluppo, il quale incoraggia idee innovative, nutrendo la nostra ossessione per una qualità di riproduzione sempre più elevata. Il nostro obiettivo è semplice – desideriamo che tu possa goderti la tua musica. Lavoriamo per raggiungere questo risultato e impieghiamo molto tempo sui nostri modelli ad alte prestazioni. Le eccezionali tecnologie e la ingegnerizzazione impiegate sui nostri prodotti costituiscono le fondamenta di tutti i nostri prodotti, permettendo anche ai modelli di basso costo di beneficiare di anni di ricerca.

    Dipingere un quadro in musica

    why cyrus 1

    Sviluppare componenti audio dalle prestazioni elevatissime richiede ingegneri audio esperti e orecchie accordate su una regolare esperienza di ascolto di musica live di diversi generi e contesti. Tutto inizia con un documento che contiene i concetti base del progetto e che descrive le caratteristiche e le tecniche che possono andare oltre l'attuale "stato dell'arte". Il team R&D di Cyrus viene poi coinvolto nello sviluppo di una serie di prototipi, ciascuno dei quali viene sottoposto ad ascolti per valutare i componenti e la struttura circuitale in evoluzione. Mentre progettiamo includendo molti concetti già noti come la messa a terra a stella e le schede multistrato, ogni progetto presenta inevitabilmente nuove opportunità per approfondire nuove tecniche di ottimizzazione del suono. Sebbene il suono sia di gran lunga l'obiettivo più importante, dobbiamo anche ingegnerizzare tenendo presenti aspetti quali la sicurezza, le emissioni e gli standard energetici. 

    Il suono Cyrus è intenzionalmente come un quadro in musica; desideriamo dipingere una ampia finestra sonora che travalichi ampiezza e profondità dell'ambiente fisico, in cui gli esecutori si collocano in posizioni realistiche, con una gamma estesa in frequenza per cogliere i suoni ambientali, e ricreare un basso profondo e accordato privo di aggiunte "commerciali" in gamma medio-bassa, il tutto con un preciso senso del ritmo e con una riproduzione accurata dei toni vocali.

    Descrizione in aggiornamento

    Each component must conform to our acoustic palette as we want all components in a system to play a part in a consistent sonic image, and never to conflict. Although detail, dynamics, soundstage and other parameters improve with each new model, the sonic signature remains constant. This is what we believe will recreate the most lifelike performance in your home. We want to resolve the fine details that reveal the emotion and passion truly great artists share with us at the recording stage. Most audio systems unintentionally filter out much of the special magic that is evident at a live performance. It is our goal to refine our art so our components transmit more of the subtle details through to your listening room.

    The Cyrus listening panel may decide to re-spin a circuit many times through the development processes in order to be sure we have explored every option to refine our design. Each board may require comparative component auditions across as many as 50 parts, each shaping small but cumulatively important changes to the overall performance.

    The logic of buying products designed to work together

    Separate components always sound better because, among other technical benefits, they each have a dedicated power supply designed for the exact purpose. Cyrus has always believed that it is vital for audio components in a system to be voiced identically; otherwise it would fall prey to acoustic chaos. For example, consider the anarchy of assembling your own sports car made up of parts originally developed for taxis, tractors and trucks. Would you reasonably expect them all to perform as a balanced supercar? No, we wouldn’t either. Cyrus believes that audio system components should be designed holistically and voiced with the same philosophy; to play harmoniously together, so they complement one another.

    Cyrus’ audiophile technologies

    why cyrus 2Servo Evolution
    Cyrus has been at the forefront of CD development since 1983 when our engineers helped develop one of the very first specialist CD players. In 2015 Cyrus wants to make the best players in the world, irrespective of price. To achieve this goal we have developed our own CD read ‘engine’ we call Servo Evolution (SE) that reads data from the disc with 20% fewer errors than leading rivals. All our CD players use this custom made for high-end audio CD ‘engine’.

    Hybrid Class D
    Until recently Cyrus had considered Class D topologies to lack the performance required for our high-end audio amplifiers. However there are many potential acoustic benefits and so following a research project, Cyrus has developed several solutions that solve barriers to Class D’s successful use. Our development of S.I.D. (Speaker Impedance Detection) means that we can automatically analyse the impedance of the connected speaker (and cable) and adjusts the Class D amplifier to accurately match the consumer’s specific loudspeakers. S.I.D. is just one of a suite of solutions that allow this valuable technology to become an exciting amplifier opportunity.

    Zero Global Feedback
    Zero Feedback is a sophisticated amplifier topology that requires experienced design engineering and manufacturing controls to work well.
    However the sonic benefits are legion, providing very good distortion characteristics among many advantages.
    Sonically this is a revealing topology suitable for our most advanced and high performance models, the Mono X amplifier platform.

    Virtual Servo pre amplifier
    Cyrus believes that in many audio circuits short, direct signal paths are best. By eliminating both the coupling capacitors or the necessity for a DC servo used in standard preamplifiers to remove DC, this ingenious Cyrus design uses fewer electrolytic capacitors. We call this circuit a Virtual Servo because it does the same job, but with fewer components.

    The perfect chassis for audio
    A striking visual feature of a Cyrus system is the aesthetic lines of the half width chassis. Created by pressure die-casting aluminium, the beauty of this monolithic chassis is however more than skin deep. 

    The hand finished casework is an integral part of the products’ sound. Cyrus has invested in sophisticated die-cast tooling to create an electrically shielded and mechanically vibration free environment for the sensitive audio circuits which are hung inside the inverted chassis.

    Microphonic interference can occur when certain components transform mechanical vibration into unwanted electrical noise if the chassis is excited. The Cyrus chassis has been designed to provide an enclosure that is immune from a wide range of frequencies. This acoustically inert enclosure protects the sensitive audio components from external microphonic influences.

    Inside a common steel chassis, components such as transformers radiate electromagnetic fields which induce unwanted electric currents and secondary magnetic fields within the ferrous box, thereby adversely affecting other components in the same enclosure. In the Cyrus die-cast chassis our choice of non-ferrous aluminium means this effect is avoided.

    Upgradeability, a designed-in concept
    This has two major benefits. Firstly, it enables customers to build up systems over time. The initial investment is never wasted as they upgrade and add complementary components to build a better system. Secondly, it’s environmentally friendly as it extends the life of older Cyrus units when customers decide they want to improve the quality of their hi-fi system.

    Many components can be returned to the factory to be upgraded to the next level up in performance. DAC cards can be added to give digital inputs to an analogue amplifier. Our advanced Qx DAC cards can be added to improve the performance of an existing DAC. All power amplifiers are gain matched, so you can improve the dynamics and resolution of your system through bi-amping or tri-amping your speakers.

    The performance of most Cyrus units can also be improved through the addition of our PSX-R2 power supplies. This feeds the attached component with strong, clean filtered power, allowing the complex electronic circuitry to perform at its best.

    Service and support
    Did you know that Cyrus regularly restores amplifiers sold up to 30 years ago? Our customers often hand down amplifiers through generations of a family and our service team can replace parts that degrade over time to restore the amp to its original glory. This allows each generation of user to enjoy the amplifier’s superior sound quality again. We estimate that 80% of our products are still in use today, making Cyrus one of the most effective users of materials in our industry. Cyrus’ longevity is clearly in sharp contrast with products made in low cost economies that may initially retail for less, but lack the long term value of better engineered products. Our customers appreciate that quality remains treasured long after the price is forgotten.

    What Influences audio quality?

    Source Resolution
    why cyrus 3

    In order to perceive the vital, low level and sometimes quite subtle sounds that are the essence of a stunning performance, we want to have as much data as possible. While compressed music from DAB or online streamed services can sound good, it does not take long, even for those new to hi-fi, to appreciate that higher bit rate music sounds much better. 

    To take advantage of the fast growing marketplace for downloadable higher bit rate music, Cyrus has developed arguably the most advanced High Definition, or HD, streaming “engine”, capable of 24 bit/192k FLAC and WAV files. We can also play most other file types as well, however, it is the high resolution CD quality and HD files that offer the most exciting sound quality. 

    The chart shows the relative data rates between likely digital sources. Although most listeners agree that Bluetooth™ music at 352k is great, true hi-fi starts with CD and HD files which sound clearly better.

    Amplifier dynamics
    amplifier dynamics

    This illustration shows the relative power of our amplifiers. As outlined in the amplifier pages, there is no substitute for power because we want to reproduce the dynamics as recorded. For example, a powerful voice should sound louder than the backing singers, and so to correctly reproduce this dynamic relationship, we need strong reserves of power. 

    The percussive sound of a drum requires high dynamic (or bursts of) power to drive the speaker and therefore the more power in reserve, the more realistic the drum will sound. The chart shows how our more sophisticated amplifiers have higher headroom available, or to put it another way, better ability to provide bursts of short term power. 

    Greater power is not about playing the music louder; it’s about presenting the difference between large and small notes so they sound realistic. 
    Power is quoted into 6Ω because this is the real-world impedance of high quality loudspeakers.
