購買概述

第一次買真空管,也不知道該怎麼選,看了很多品項,慢慢建立自己的挑選模式,一開始當然是用自己的既定印象來選擇,這次是以推力、瓦數來選擇,還多看了電源供應。

最初是想要購買 PrimaLuna 的機器,但是要價十幾萬,又是第一次買真空管,想一想還是先買台十分之一左右的管機來試水溫,逛了逛淘寶,中國的規模經濟真厲害,可以把價格壓這麼低。

我對基本電學,可說是完全不暸解,只知道好的機器電容都很多,所以會先看看介紹頁面有沒有貼內部的照片,零件數量夠多、電容夠大,好像有聽過這些零件的牌子,就把他加入比對清單。

再來家裡有一台單端 EL34* 了,所以想找其他類型的管機,聽聽不同音色,印象中 KT88 也是耳熟能詳的型號,就從這方面去找,看了一些文章說推挽會影響音質,可是我第一次買又怕買太小推不動,後來看到單端並聯這個產品,各方面都滿足我的需求,所以選擇了這款擴大機。

* 型號是 Unison Research Simply Two,上面有金色的名牌,不過是我爸的,在接觸音響前對家裡這些器材都不是很了解,只知道家裡也有這類型的機器,管子上面寫著 EL34,直到自己想買才仔細看了一下他的牌子。

在網路上看好像沒有很大台,以為只有一台筆電的大小,物流送到後,比家裡那台單端大了一倍,加上包裝後將近 30 公斤的重量,運費花了 1300 多,最可怕的是第一次拿這麼重的東西,花了好大力氣才把它放到架子上。

 

評價

把前級放大跟推動管都換掉之後,現在只剩下功率管還是使用出廠配置,聲音表現在解析還有三頻分離度都有改善,就是少了點厚實的那一味。

價格算是他的優勢,用料沒有很高級,但是該做的都有做到,作為管機入門還不錯,音量大概轉到 兩點鐘位置 就是推力的極限,再往上轉喇叭感覺會承受不了,而且聲音有失真感。

測了三個書架喇叭,中高頻表現中等,在可以接受的水平,低頻表現不錯,在一定的音量下,很有氣勢,能量充沛,不過再往下的極低頻,下不去,小音量的時候聲音略為扁平,音場表現取決於喇叭特性,他有展現出來包圍感,但是定位不夠清楚。

如果聽的音樂類型小品樂器、人聲居多,使用 EL34 體驗會比較好,想聽流行音樂、擊鼓聲,適合用 KT88。

  1. Thanks for your personal marvelous posting! I certainly enjoyed reading it, you are a great author.I will be sure to bookmark your blog and definitely will
    come back at some point. I want to encourage yourself to continue your great job,
    have a nice afternoon!

  2. OK — been using this thing for maybe five months now and it’s stuck on my phone, so thought I’d say something since a lad on another thread asked me the other day. Am based in the UK, mostly do football and horses, a fiver here and there, just so you know where I’m coming from.

    What got me on it was actually embarrassing — I could never get my head round what an ew payout would be with 1/5 odds a place. I’d just eyeball it and moan when the payout landed. Now stick my stake in before I place anything, even a simple single bet.

    Their single bet calculator is the part I use most — you drop in your stake, the odds and it spits out profit and total return with no faffing, fractions or decimals. It also handles the fiddly ones — acca and treble returns, lucky 15s, a yankee, which is where most people I know lose track. If you want a look, it’s over at [url=https://freebet-calculator.com/bet-calculator/matched-betting]exchange bet calculator[/url] — free, no signup.

    One thing that really changed how I bet is the geekier bits. They’ve got an implied probability calculator which shows you how much the bookie’s taking, plus a kelly staking tool — I run quarter kelly as the full version is terrifying. The dutch tool is decent for when I’m covering two or three runners.

    Couple of gripes. The design is pretty plain — not much frills, it’s clearly function over form. On my phone it’s usable but the bigger tables are a squeeze. And no app, it’s a website and that’s it — doesn’t bother me just flagging it.

    Right, that’s me. Doesn’t cost anything, barely any ads, does what it says. Anyone who even now does the maths on paper, have a look — saved me a load of arguments with the bookie.
