Audiolab 8300-as széria tulajdonságai (angol nyelven)
The 8300CD demonstrates a level of fine detail, transparency, soundstage depth, dynamic range and musical flow across all sources. It is both an exceptional CD player and a top-class external DAC/digital preamp, able to make the most of your CD collection. While delivering an enormous sonic boost to external digital audio sources it now extends its resolution to 32-bit/384kHz and DSD compatibility via USB.
In the all-new Audiolab 8300 Series, we’ve asked fundamental questions about how people enjoy the music they love and to make sure their hi-fi is as easy to use as it is easy on the ears.
While our engineers have referenced the blueprint of the 8200, each component has come under scrutiny to create a hi-fi system leaps ahead of what is already a leader in its field. With more efficient components, high- definition audio format technology and redefined aesthetics, the 8300 Series has raised the bar, yet again. Audiolab proudly present the new 8300A, 8300CD and 8300MB. Completely redesigned from scratch, our new integrated amplifier, the 8300A is miles ahead of what was already an industry-leader. Higher power, an additional phono stage and new Audiolab styling means the amplifier is more stylish and more versatile than ever. Most importantly it's new, ultra-efficient circuitry and streamlined components create a listening experience which brings new definition to your favourite music.
Control Where You Need It
The 8300CD adds full digital preamp functionality, with volume and source selection accessible via the player’s front panel and remote handset. This means the 8300CD can be connected directly to a stereo power amp, or a pair of monoblocks like the new Audiolab 8300MB, as well as to a traditional integrated amp like the equally new Audiolab 8300A.
8300 Series also allows control of music playing from a PC/Mac/media device via USB. When connected to a computer, the 8300CD not only identifies itself as an asynchronous DAC, but also as a HID-compatible device (Human Interface Device). This allows driverless control of the PC/Mac/media player (Play, Pause, Stop, Track Select etc).
The 8300 series’ blasted aluminium finish, CNC routed aluminium dials and display certainly look cutting-edge, yet with every Audiolab product, form follows function. The new display and controls enable a fast and intuitive access through the vast routing options and filter settings in both the A and CD.
The new mechanism also reduces the occurrence of disc rejection, able to play CDs that other CD players may reject for being imperfect from dirt or damage. Its digital buffer circuit is a perfect mate to the asynchronous input of the DAC, improving even this area of performance. A final benefit is increased disc stability and reduced susceptibility to resonance, which additionally contributes to the overall improved sound quality.
On the 8300A Engineers have developed a new phono stage catering for the resurgence in vinyl records with MM and MC configurations accessible via the front panel controls.
12V remote trigger loop feature on all units so as one device is switched on, paired units are switched into or out of standby mode - working as one system for quick operation.
The 32-bit ESS Sabre DAC as used inside the 8300CD continues to have a reputation as the best-sounding DAC chip available, and most CD players that use it are much more costly designs. In terms of the way it measures, its distortion figures are extraordinarily low. Around the DAC there are extensive measures to reduce jitter to vanishingly low levels, of a nature you’d expect to see only in much more expensive players.
The conversion process within Audiolab 8300CD results in the 512 DAC elements (256 DACs per channel) each operating at 84.672MHz – all digital audio sources, whatever the sample rate, are upsampled or oversampled to this frequency. This results in a conversion process that is switching 3840 times higher than the typical audio upper bandwidth of 22kHz. Without this Digital upsampling technology, the analogue filters would likely affect frequencies at or near the audible range, resulting in unwanted level and phase variation within the audio band.
The inclusions of the Hyperstream modulator means optimal transient response is achieved, thus eliminating dynamic response deficiencies and noise floor modulation artifacts typical of traditionally designed Delta-Sigma DACs.
The new 8300CD can accept and process data up to 32-bit/384kHz; this is a far higher specification than that required even by current hi-res music formats, ensuring the 8300CD is fully equipped for future advances in ultra-high-definition digital sound.
The USB input now also accepts DSD data, as well as PCM. This is a significant addition, as DSD has an important role to play in the developing high-res digital download scene. Accordingly, the filter section now includes four extra filters for DSD playback, allowing the user to optimise the noise floor to suit the performance of the source file and the bandwidth of associated equipment such as amplifiers and loudspeakers.
The uprated digital processing associated with the increased resolution at the USB input delivers additional sonic benefits, for both CD replay and other connected digital sources, whatever the resolution of the file. In advancing the capability of the USB input to include files of up to 32-bit/384kHz, the processing of data preceding and within the Sabre DAC has increased the subjective resolution of musical detail and dynamics, resulting in a more energetic and transparent performance that sets a new standard for CD players at this price level.
Digital Filter Optimisation
As digital audio reproduction technology has progressed, the importance of the characteristics of reconstruction digital filters has become more appreciated. The Audiolab 8300CD features user-selectable digital filters for optimal listening. These filter settings allow the user to tune the 8300CD’s performance to suit his or her preference, depending on system configuration and musical taste. These filters are available for CD and PCM audio via digital inputs.
• Optimal Spectrum
• Optimal Transient
• Optimal Transient XD
• Optimal Transient DD
• Sharp Roll Off
• Slow Roll Off
• Minimum Phase
the 8300CD also adds four DSD filters that progressively attenuate the out of audio bandwidth noise floor. Given stable, wide-bandwidth amplification and loudspeakers that can handle high power ultrasonic output, the user can choose the widest bandwidth setting of 70K. More modest equipment will benefit from the lower bandwidth settings, as may files that contain little or no recorded ultrasonic musical detail.
While striving to achieve the most supreme sound quality, each stage of Audiolab product development is focused on usability. In particular with the 8300A, ensuring simple yet in-depth control, veteran amp designer, Jan Ertner build the amplifier functionality around the new display. This means users can easily find their way around the versatile configurations the amplifier offers, even while being much more advanced than its predecessors. The amplifier can behave as an integrated amplifier, power amplifier, pre-amplifier and a split pre-amplifier - easily paired with a multitude of hi-fi systems.
The 8300A works as coherently inside as it does on the outside - By taking a completely new approach to the layout, a dual mono structure means inter-channel interference is minimised. Crucial components processing audio and the power supply are completely separated as far as possible.
Our new technology - Active Current Delivery also ensures a completely clean sound up to the point of clipping, then its advanced microprocessor limits the output, which guarantees no audible distortion, even at its louder output of 75W RMS.
The 8300MB is quite possibly the perfect example of Audiolab's goal to effortlessly reproduce music with exquisite detail. Not only is 8300MB an extremely powerful amplifier, offering 250W of pure power with high current drive capability, but it also features a fully balanced power stage.
Internally the 8300MB is arranged as two complete power amplifiers which are bridge coupled to the loudspeaker terminals. Each power amplification stage is fed from one of the terminals of the balanced input, therefore the 8300MB operates as a fully balanced amplifier right through to the speaker output.
The benefits are a high level of noise rejection and lower transient distortion plus the ability of the amplifier to draw maximum current from the power supply as required to follow the musical waveform accurately.
It all adds up to a startlingly vivid and highly impactful musical performance that will put more energy into your loudspeakers as well as control them like never before.
