Amplificator Integrat Yamaha A-S501
Boxe Wharfedale Diamond 230
ToP-ART Design and ART Base Ensure Optimum Sound When processing and transmission of the audio signal is simple and direct there is less chance of it being affected by noise and distortion. Yamaha′s amplifier design technology called ToP-ART features an I/O (input to output) Direct Symmetrical Design, with left and right channels organised in a straight, symmetrical layout for highest signal purity. In addition, the ART (Anti-Resonance and Tough) Base bottom chassis and a solid centre bar provide high-rigidity support and vibration damping. These Yamaha design innovations contribute to this amplifiers′ rich audio reproduction with abundant musicality.
Custom-made power transformer, custom-made block capacitors, two direct signal path speaker relays, one-point grounding system, aluminium-extruded heat sinks and other top-quality parts effortlessly handle demanding audio signal conditions. The quality of each individual part, as well as how they work together, basically determines the sound quality of any component. Yamaha uses only very high quality parts, carefully selected and tested.
Yamaha, with a long history of over 125 years as a musical instrument maker, also has a high reputation for HiFi components. The A-S501 is created by taking advantage of this rich experience and high technological expertise. Based on the concept of “Natural Sound”, for reproducing all music as it really sounds, and built with scrupulous care from circuit design to basic sound production, even though an entry model it reproduces high sound quality and musically rich sound.
The Pure Direct mode causes the music signals to travel the shortest possible circuit route, bypassing the buffer amp and the tone, loudness and balance controls to virtually eliminate any signal degradation for the purest sound quality.
The A-S501 also feature a new analogue loudness control on the front panel that uses electronic volume for higher sound quality, which lets you adjust the loudness effect as desired. Separate from the overall volume, this controls the balance of the low- and high- frequency sounds, providing full tonal range at any volume level, compensating for the natural loss in the human ear of high and low frequencies at soft levels.
Gold-plated terminals ensure a high quality connection that prevents signal loss. The A-S501 have Gold-plated speaker terminals and RCA (CD, Phono) and coaxial terminals.
The A-S501 is equipped for digital audio input with both optical and coaxial terminals. The optical is for receiving audio from a TV, and the coaxial for receiving audio from a Blu-ray player. The audio stays in the digital domain, giving you pure, pristine dynamic sound for all your entertainment sources, from sports and other programmes to movies and concerts.
With the YBA-11, you′ll be able to stream music wirelessly from a Bluetooth capable mobile phone or a PC to the Network receiver. Thanks to the digital connection and aptX® audio coding algorithm, you′ll enjoy wireless music streaming with optimum sound quality. You can also conveniently power the YBA-11 via the DC-out connection on the rear panel of the amplifier.
You can connect two separate speaker systems in different rooms and switch between them, or have them both playing at the same time. There are four terminals, so by just pushing a button, you can switch speakers to match the sound source.
A terminal for connecting a subwoofer is provided, allowing you to increase the bass output of your system for a more powerful sound with better overall sound quality.
You can connect a turntable with an MM phono cartridge to play vinyl records. This lets you enjoy not only CDs, but also analogue record sound from an amp with the latest digital/analogue technology.
With a beautifully simple and unique design inherited directly from Yamaha′s HiFi audio components, this amplifier also boast an easy-to-operate button layout. The aluminium front panel has a richly textured silver hairline finish. The control knobs are also of the same luxurious construction as used on our top-end models.
The clean, simple design of the remote control provides easy-to-understand one-hand operation. The easy-to-use design makes it simple to adjust song volume and order. The unit has a sophisticated looking hairline finish that matches the design of the amplifiers. You can also use the remote to control a Yamaha CD player.
The rotary encoder makes it quick and easy to select input sources. The luxury hairline finish material offers a nice tactile feeling. LEDs clearly show which source is selected, so you can easily switch sources even in a dark room.
The amplifier has a power management function that detects when it hasn't been used for a long time (about 8 hours) even though the power is on, and automatically shifts it into standby mode. So even if you forget to turn it off, power consumption will be minimised.

Quite simply put, the Wharfedale Diamond is one of our most successful speaker series, if not one of the most successful hi-fi speaker series ever. We can justify this as year on year, the Diamond Series has broke the mould for combining award winning sound quality unforeseen at this price.
From 1982 Wharfedale Diamond has meant one thing − impeccable performance at an affordable price. Today we are pleased to bring you the latest series of loudspeakers from Wharfedale that aspires to this tradition − Diamond 200 Series.
Foremost in the design criteria for Diamond 200 is the ongoing research into loudspeaker driver sound quality. The speaker series uses our famous woven Kevlar cone form, drawing influence from the flagship Jade Series.
While honing the internal crossover and using stronger magnets on the rear of the Diamond 220 for example, aesthetics and construction have been improved too. The Diamond 200 Series benefits from an all new lacquered front baffle and cosmetically enhanced veneers.
Only when the acousting tests are deemed truly satisfying are the loudspeakers designs signed-off for production, ensuring that each speaker model fulfils its eventual owner's drwams of musically enjoyable reproduction from Britain's Most Famous Loudspeakers.
