DAC Beresford TC-7533 Bushmaster 

nowy DAC i wzmacniacz słuchawkowy od Stanleya Beresforda

Zmiany w stosunku do TC-7530:

 
- szersze pasmo odbiornika TOSLINK. 25MHz zamiast 15MHz.
- szerszy zakres dynamiki
- wbudowany dodatkowy filtr zasilania
- niższy poziom szumu
- dokładniejsza regulacja głośności dla słuchawek
Balance control with a small balance range. The balance control is hidden behind the volume control.

 Zupełnie inna architektura wewnętrzna niż TC-7520,

Nowoczesny odbiornik cyfrowy Wolfson WM8804,

DAC Wolfson i pasywny stopień analogowy,

3-punktowa stabilizacja napięcia,

Ręczna lub automatyczna detekcja wejścia cyfrowego

Wejścia: 2x coaxial , 2x toslink

Wyjścia: RCA fixed , słuchawkowe

 OPINIE o Beresford Bushmaster :

"IBass is a revelation, quite staggering when I was playing Avatar last night with its transient thumps and huge waves of deep bass."

"Stereo focus and fine detail is a step-up from what I have heard before - from StanDACs or anything else for that matter.

Delicacy, fine detail, articulation - all exemplary.."

24Bit/192KHz capability with frequency response down to DC.

The majority of DAC chips are used in circuit designs for use from 20Hz to 20KHz. But DVD audio can go down to 5Hz or lower. The Bushmaster now makes it possible to enjoy extended bass.

High accuracy crystal controlled receiver chip for low jitter. 

Many agree that a low jitter ability heavily influences the performance of a DAC. The Bushmaster uses a crystal controlled receiver with one of the lowest jitter performance possible from a receiver chip. At 50ps few other DACs can match or surpass the Bushmaster in terms of jitter rejection.

Asynchronous SPDIF to I2S signal transfer

In order to correct timing and data speed transfer errors the TC-7533 uses a asynchronous buffer with a length of 1024 bits to take care of time period related errors.

Direct Coupled Analogue Output Stage

There are no opamps, muting circuits, or capacitors between the DAC chip and the output sockets to affect the accuracy of the audio signal. This allows the Bushmaster to operate down to 1Hz. The Bushmaster is therefore also suitable for DVD audio application, which can go down to 5Hz or lower.

Simple Filter Circuit. 

There has been much debate as to how much damage is done to the audio signal by the various digital and analogue filtering networks that are found in a DAC design, and whether filters contribute to grainy high frequencies. The technology used in the Beresford Bushmaster relies instead on a simple HF analogue filter that operates outside any feedback circuit and outside the audio spectrum. This makes the Bushmaster less prone to anti aliasing filter residues and noise, and produces a far cleaner and detailed treble response.

High Current Class A-B headphone circuit. 

The ever increasing popularity of larger cones in headphones has put new demands on headphone amplifiers. Larger cones require a larger current drive capability from the headphone circuit in order to reproduce bass frequencies with depth and impact.
The new generations of high-end headphones in particular have up to now only been able to operate properly on expensive stand-alone headphone amplifiers. The Bushmaster in built headphone amplifier is designed to drive even the latest range of high-end headphones and reproduce musical detail that these headphones are capable of.

DC Linearizer Low Noise Filter

External DC power supplies are a known source of RF noise. Our own unique DC Linearizer circuit transforms almost all of that RF noise into a clean DC voltage. The result is then fed to a Low Drop Out regulator circuit. We employ separate regulators for the supply of power to the TOSLINK and coax input circuit, digital and analogue signal processing circuit, and the headphone amplifier circuit. The result is an analogue sound with firmer and deeper bass, more detailed midrange, and crystal clear treble.
