What is the Wharfedale Diamond A1?
The Diamond A1 is a relatively high-end pair of Bluetooth speakers, and the active, more attractive version of the Wharfedale Diamond 220.
If you’re after something more room-filling and high-fidelity than the army of one-box wireless speakers out there, these are a truly impressive option.
Wharfedale Diamond A1 – Design and features
Unlike the majority of Bluetooth speaker systems around, you don’t get one box, or even two boxes; three separate boxes for the Diamond A1. That’s because, in addition to the pair of stereo speakers, there’s a wireless control box that handles all the pairing and physical inputs.
But let’s start with the speakers, which are really rather classy. They might be based on the Diamond 220, but aesthetically they have far more going on, with radius corners and a choice of either gloss white or black for the front baffle. The real touch of panache, however, comes from black leatherette wrapped around the edges of the cabinet.
Mounted into the baffle of each is a 130mm mid-bass driver and a 25mm fabric dome tweeter, driven by 50W of internal amplification. There’s no slave and master here, with both speakers having their own power – they’re identical, and each has a switch to designate whether it’s the left or right channel.
Of course, this means that the speakers don’t need to be tied together by any kind of cable. The downside is that each requires its own power input, and Wharfedale has chosen to use external power supplies rather than integrating PSUs inside the speakers.
The choice to have a separate control hub adds yet another mains adapter and plug socket into the equation, so the wireless dream could turn into a nightmare if you can’t easily hide all those wires, transformers and plugs somewhere.
The Wharfedale H1 hub looks a little like a router. On the front is an IR receiver for the supplied remote control, while on the top is a small display and touch controls for power, volume up and down, and source selection. Around the back are coaxial and optical inputs for digital sources, and an RCA stereo phono line input. There’s also a micro-USB socket for firmware updates.
The remote control is light and plasticky, but looks far nicer than many of the cheap units usually supplied with Bluetooth speakers – when they have a remote at all.
Wharfedale Diamond A1 – Sound quality
Setting up the Diamond A1 is a bit of a faff, mainly a result of that separate control hub. There’s a series of button presses required, as well as ensuring one of the speakers is set as the left channel and the other as the right.
With that done, and a Bluetooth device paired, it’s all ready to go. And it impresses immediately.
Starting with something expansive – The National’s ‘The System Only Dreams in Total Darkness’ – the Diamond A1 rose to the challenge, forming a wide soundstage and reproducing the guitar particularly well.
A run through Massive Attack’s iconic ‘Blue Lines’ album proved the Diamond A1 have a tightly controlled bass – although since their bass ports are on the back, this will be affected by how much space you give them to breathe. At the very least, I’d leave a gap of three inches behind to avoid booming and a disconnect with the mid-range.
There’s a handy trim control on the rear of each speaker, though, with the ability to boost or reduce the bottom end. I found it worked well to increase the bass when using the A1 in a larger room.
Something a little subtler, such as Iron & Wine’s ‘Beast Epic’ album, exposes the Diamond A1’s limitations. Vocals don’t quite have the realism, and the mid-range doesn’t have the separation that can be achieved by spending a little more on a dedicated hi-fi system. For the money, though, this still offers impressive performance.
Should I buy the Wharfedale Diamond A1?
The Diamond A1 are super-impressive for the money. They offer excellent scale and power, as well as revealing a decent level of detail. For truly room-filling hi-fi sound, there’s very little that can touch them at this price. And they look far more expensive than they are.
The lack of aptX HD support – so no wireless Hi-Res Audio streaming – might concern, but the Diamond A1 don’t quite have the finesse to resolve that extra detail. Really, you’ll need to spend quite a lot more to get to that level.
Verdict
Excellent-sounding Bluetooth speakers with a ton of sonic scale for the money.
CMS Sotto Voce racks are not just vastly less expensive than the rm’s state- of-the-art efforts; they also offer comparable performance in a more tradi- tional and appealing package. The frame and shelves are made of gorgeous Sapele African hardwood (natural or optional black nish) with sturdy metal connections milled from billet aluminum. The sonic improvements are not subtle—bass tightens, transients gain more verve yet maintain better control, rhythms sharpen, and low-level noise plummets. It’s that last factor that opens the soundstage and is key to the SV’s remarkable ability to elicit dimensionality from a recording. Fully upgradeable to accommodate CMS’ upscale array of “ lters” (they replace the stock shelves but are mechanically far more com- plex). The lters provide further noise reduction, while the “purity quotient” takes a sizable jump. Available in three heights, the tallest, at 38″, is a four-tier unit that offers 10″ spacing out of the box yet is easily adjustable.
回到純粹播放 CD 的原點
近年的光碟播放機除了能謓取 CD 及 SACD 光碟之外還加入了大量功能,已變成多功能的播放器,例如增設大量輸入及輸出接口、網上串流播放功能、USB 輸入及解碼播放高清檔案、無線接駁等等多不勝數的功能,可是這樣需要非常複雜和精密設計的線路及大量高質電子零件,並需要有良好的抗干擾措施和高階的電源供應等等配套才能達到高音質的境界,如此一來生產成本便會變得高昂。 D-380 CD 播放機的設計重點以簡單直接為主,就是純粹為了能將CD光碟的訊源如實地重現出來,所以不設任何額外的附加功能,機背只設有一組立體聲非平衡模擬輸出及兩組數碼輸出 (同軸及光纖,可於遙控器開啟或關閉), 對於純CD發燒友來説絕對足夠。
結他彈跳活潑中頻磁性迷人
再聽聽 Derrin Nauendorf – Live At The Boardwalk 輯,這位 Derrin 結他演奏家在 Boardwalk 倶樂部的現場表演,大部份時間都是他在自彈自唱,並且配合 David Downing 的敲擊拍和。第一首 Ghost Town 開始時的結他獨奏已感到聲音充滿跳躍的彈性,空間感十足,而低 頻絕大部份是以結他彈奏弦線或敲打各種敲擊樂器出來的聲音,因此並沒有猛烈雄渾的低頻,而是量感適中線條清晰的低頻。隨後而來 Derrin的歌聲亦充滿活生感,嗓子略厚而且感覺磁性迷人。D-380 以真空管輸出模式來播放,結他的音效感覺既真實又自然|人聲則渾厚並充滿感情。此外雖然歌曲編排十分簡單,但聲 音密度也頗高,整體感費豐富迷人。
