頂級旗艦技術傳承,盡顯精密箱體聲效果 – Hailey 2.2 三路三單元座地揚聲器

Hailey 2.2 以旗艦產品 Sonja 逼真的自然聲音為藍本,沿用與 Sonja 2 相同採用令人驚嘆的世界級精密製造技術,包括 BilletDome 高音單元和 ViseCoil 低音電感器。聲音表現結果驚人,除了保留了旗艦的優點之外;還令 Hailey 系列推至另一境界。

自家工藝追求極致

YG Acoustics 的揚聲器設計均源生於他們引以為傲的六大技術,無論是箱體、單元振膜、磁鐵,都是自家研製。廠方稱其振膜製作技術為 BilletCore 磁鐵製作技術則為 ForgeCore。不只如此,就連接駁端子、腳釘、螺絲、甚至連螺母墊片等也是他們自家車製,可見對產品的每個細節都是何等執著。

全新設計的 BilletDome 單元

Hailey 2.2 用上全新的 BilletDome 高音單元,無共振的軟球形高音其使用的鋁框(airframe)非常輕(僅重 30mg),但主要的部分卻有傳統單元的十四倍厚,使這個高音的結構強度更甚於使用其他堅硬材質的高音。這個高音使用了廠方專利的「ingenious Forgecore 磁鐵〕驅動 系統,亦是在 YG Acosutics 工廠使用 3D 幾何繪圖,再配合 CNC 切割製成,達到更低的失真與更寬廣的高頻響應。

三路三單元箱核體設計

驟眼外觀看似與 Hailey 1.2 無分別,同樣是三路三單元箱體尺寸相若設計的Hailey,由於上一代的低音模組設於背面近部位置,現在 Hailey 2.2 則改為近頂位置,大大縮短了內部接線行程,令失真減少。

音色清晰易於驅動

YG Acoustics 透過自行開發的軟體計算,力求頻率響應與時問相位一致,也就是獨家的。DualCoherent 技術。在低音分音器裡,使用了 ViseCoil 技術下製作的電容,能減少 25% 的能量損耗,並增加 60% 的線性表現, Sonja XV 的低音單元更容易被擴音機所控制。在中、高音分音器裡,則用了 ToroAir 的空心電感,配以 CNC 製作而成,有效消除串音並有助細節的表現。加上專利的 “FocusElimination” 抗共振技術,能讓揚聲器因共振造成的能量損失降到最低,重現最清晰透明的音色。

Wharfedale Evo 4.4 review – WhatHiFi?

Think of Wharfedale and we can pretty much guarantee the next word to enter your mind is Diamond. So successful have the various budget Diamond ranges been over the decades that it’s easy to forget that the company also makes premium products, such as the new Evo 4.4 floorstanders on test here.

These are the biggest and priciest offerings in the company’s new Evo range and are packed full of so much technology that we had to double-check the speaker’s price tag to make sure it was for a pair of speakers, rather than just one.

Build

What kind of technology? Well, there’s the Air Motion Transformer tweeter for starters. While there are a few similarly priced speakers that use such a unit, it’s a type of design more usually seen at far higher prices.

An AMT works by having a light, pleated diaphragm driven across its surface by a row of carefully placed magnets. The pleats contract or expand according to the music signal, squeezing the air between them in the process to create the sound wave. The sound from this kind of unit is claimed to be fast because of the light diaphragm, and accurate due to the complete surface area being driven.

The 55 x 80 mm AMT hands over to another unusual drive unit, a dome midrange, at a relatively high 4.7kHz. Few speakers use a dome midrange because of the cost and difficulty of development, but the one used in the 4.4 has a 50mm soft dome coated with a damping compound to control resonances. There’s also a specially shaped chamber behind the dome that scatters and absorbs the diaphragm’s rearward sound, so reducing distortion and improving detail.

This dome midrange unit has a wide frequency response ranging from 800Hz to 5kHz. This response along with the powerful motor system helps it integrate with the AMT tweeter as well as the twin woven Kevlar bass drivers that sit below it on the front panel. The crossover point between the midrange and bass drivers is 1.2 kHz.

If you’re thinking that any speaker that stands 106cm tall and has twin 15cm bass drivers should deliver plenty in the way of bass, you’d be right.

The output of those two bass drivers is helped by a downward-facing port arrangement where the low frequency sound fires out through a gap between the base of the speaker cabinet and the floor plinth. This is a technique that Wharfedale has refined in recent years and is claimed to better match the acoustic output of the port to the room.

The Evo 4.4’s build quality is good for the price. We like the way the elegantly curved cabinet is put together. It’s strategically braced and damped to provide a solid, low resonance platform for the drive units to work from. There are three finish options – black, white and walnut. The standard of fit and finish on our review samples is good.

Compatibility

These are pretty big speakers, and sound best well away from the rear and side walls in our medium-sized test room. Place the speakers too close to either room boundary and that powerful low end starts to dominate.

Get it right though, and add suitably talented electronics into equation, and you’ll find the Evo 4.4s to be superb speakers for the money. We think something like a Cyrus CDi CD player coupled with Rega’s Elex-R would be a good starting point for a system.

The Evo 4.4 has a nominal impedance of 4 ohms, but it barely dips below that point at its minimum, so shouldn’t be a particularly hard speaker for an amplifier to drive. That means the absolute quality of the amplifier is going to be the decider rather than its outright grunt.

Sound

It won’t come as a surprise that relatively big speakers produce a large-scale sound with plenty of authority. We listen to Dvorak’s New World Symphony and are impressed by the Wharfedale’s dynamic reach and ability to cope with a mass of instrumentation with composure. They go loud with an ease that suggests plenty of headroom and remain organised when the recording gets demanding.

The transparency and subtlety these Wharfedales display is far less expected. There’s a real feeling that these speakers are digging deep into the recording and presenting that information in an honest way. They track the complete envelope of a note well, clearly defining leading and trailing edges without sounding overly etched.

Rivals such as the excellent Fyne Audio F501s sound more forward, and perhaps more exciting because of that, but over a longer listen the Evo 4.4’s easier-going presentation is more natural and convincing. It’s the kind of sound that appeals over the long term rather than during a short audition at a dealer.

The combination of the AMT tweeter and dome midrange delivers much in the way of resolution and transparency. These speakers sound impressively articulate through these frequencies and deliver vocal-led music such as Mount The Air from The Unthanks brilliantly. There’s nuance and texture in voices that helps to communicate emotions really well.

Tying everything together is a fine sense of timing that results in surefooted rhythms and the ability to present a mass of instrumentation as a cohesive and musical whole. The longer we listen, the less we find ourselves analysing the sound, and the more we simply enjoy the results.

The Wharfedale’s refined tonal presentation is nicely judged, treading that fine line between attack and smoothness well. Over our review sessions we listen to everything from Bob Marley and Bruce Springsteen right the way through to Orff’s Carmina Burana and never feel that these Evos are dictating our choice.

Verdict

These floorstanders prove that Wharfedale has the ability to mix it with the very best at more premium prices. The Evo 4.4s are entertaining and detailed with enough in the way of refinement to make them an excellent long-term choice. If you’re looking for floorstanders at this level, put these towers high on your shortlist. You won’t regret it.

2019年度最超值的CD機+合併式擴音機 Luxman D-N150 + SQ-N150

回看 2017 年,當時我們在東京訪問過 Luxman 前社長土井和幸先生。他指出,品牌已重回日本 Hi Fi 品牌銷量榜三甲之列,而且消費者平均年齡比另外兩個品牌為低。他們致力向多線發展,利用 DAC、耳擴等產品開拓年輕人市場,另 一方面又不會忽視銀髮族對真空管的鍾愛。 當品牌傳承到現任社長川上晃義手上,將原本兩個發展 方向進行匯流,成為 NeoClassico II 系列的 D-N150 CD 機、 SQ-N150 真空管合併機,齊集機身細小、CD機、USB DAC 及真空管等四項元素,而且售價不高,就算是社會新鮮人稍為努力已負擔得起,創造出令兩輩發燒友都感興趣的新系 列。

A4 Size

D-N150、SQ-N150 是 NeoClassico II 系列成員,特色是佔地面積同為 210 x 297mm,即是一張 A4 紙大小,一般書桌也能容納之,只需要為 SQ-N150 真空管合併機機頂留有空間散熱即可。Luxman 向來喜歡在真空管產品上加入木材元素, 與晶體管的銀色鋁合金外殼形成對比,而 NeoClassico 則是結合了銀色鋁合金外殼和真空管,為熟悉 Luxman 的朋友帶來新鮮感。而造工方面,是品牌一貫的高水準。

D-N150 是一款 CD 機,它用上與高級型號 D-380 一樣的 CD機芯; DA晶片是德州儀器 PCM5102A; 品牌強調機內所用的元件都經過實際聆聽去作出挑選,包括變壓器、電容、 作為機內接線的無氧銅等等。 CD 以外,它亦擁有 USB 輸入,支援最高 PCM 32bit/192kHz。這也是第一款備有 Bulk Pet USB 技術的 Luxman 產品。Bulk Pet 是日本 INTERFACE Co.,LTD. 的專利技 術,能夠透過調整電腦 CPU 的工作情況去改變聲音表現,並 設有四種聲音模式供用家選擇。雖然調整CPU需要用上同步傳輸技術,但實際的數碼音頻訊號傳輸還是以非同步方式進 行,即是 USB DAC 還是可以通過緩衝記憶體暫存數碼訊號, 然後重新配上時脈訊號。

真空管之美

SQ-N150 雖然細小,不過並非如不少市場同類體積的真空管合併機那般採用前膽後石架構,它是全真空管放大線路,設有輸出變壓器。SQ-N150 的輸入級選用一對 JJ Electronic ECC83 真空管。再利用四支 JJ Electronic EL84 建構出推挽線路,提供每聲道 10W(6Ω) 輸出。

它內建 MM/MC 唱頭放線路。此外,亦有音品管理功能, 方便對應不同的聆聽空間及擺位。 介紹過兩位主角之後,接下來就是實際試聽。把它們放到細試音室,並找來一對 PMC twenty 5. 23 小型座地揚聲器、 Amphion Helium 410 書架仔、一對Analysis Plus Power Oval 2 MK2電源線、inakustik NF-1302 RCA訊號線、TiGLON MSS-DF100SP-HSE 喇叭線,成為試音配套。 這對 Luxman 西裝推動PMC twenty 5. 23,雖然火氣有點收歛,畢竟 PMC 與不少真空管擴音機八字不合,已非新鮮事,不過 SQ-N150 仍然令這對揚聲器展現出整齊、三頻平均的聲音,又有真空管的暖和與悅耳,已經收貨了。只要不播放大編制的管弦樂或是電子舞曲,效果還是不錯的,尤其是那柔美音色,令不少美麗旋律變得更動聽。

拒絕濃郁音染

有如一段時間,市場上各種小型真空管器材,總是強調 那成熟、溫厚的中音,以老成、動態平緩的人聲取悅聽眾, 卻難掩其偏聲、窄頻等缺點。

Luxman D-N150、SQ-N150 絕不是強烈濃郁音染、慢聲當韻味的類型,那當然擁有溫暖、中音與中低音厚潤、甜美 的高音光澤等等,一些大眾所認為真空管應有的聲音特質。 但它是厚而不濃、是清甜不是死甜、是輕微的金黃色光輝而非昏黃,更重要是沒有偏重某一頻段,速度亦夠快。 將揚聲器換成 Amphion Helium 410,Luxman 西裝就更加如魚得水,三頻更加平直,動態對比更大,但不會失去溫暖與柔美。它的中、低音分量其實不錯的,鋼琴與低音提琴不會過於虛浮。重心放在中低音上,因此音像不會細,而且安定。 定位明確,輪廓不會鬆散。把揚聲器彼此距離定為一點七米左右,音場還是十分平均,不會斷開,也不會集中在中央。 這套組合最大吸引之處,在於人聲及弦樂,那種厚潤、 圓滑又不失細節。全頻收結速度快、不留尾巴。雖然對各種細節有明顯修飾,聽起來更加美麗,但沒有偏離現實之餘, 也沒有磨走各種細節,分析力依然是現代音響器材水準。
