- #2 [tonylaibach], 23-02-10 20:53I've used them.
No degradation that I can hear. - #3 [homan8577], 23-02-10 22:34#2
did you buy them via their online ship and they ship them to you or via A & M Promotions in Hong Kong as listed here?

I tried to open the link of A & M Promotions but the link fails. I searched A & M Promotions still found nothing related. -
- #4 [chuttt], 23-02-11 01:47I have used Rothwell and also Harrison Lab. Both good although I like Harrison Lab a bit better.

- #6 [homan8577], 23-02-11 10:21Anyone knows how I can choose for the correction version of the attenuator for my need?
there are a few options on the site:
version: -10db / -15db / -20db
model: standard/ for source
Some information for my system, when listening to LP, 10 o'clock is the max I can tolerate, 8 o'clock is min I would accept, anything lower than that would be hardly audible. I am using Goldpoint STEPPED attenuator for my pre-amp.
With thanks

-10dB 大約係吵大交同平時講嘢聲量分別。
我知道iPhone 有App可以測量sound dB level。我知道有人用佢嚟調校超低音。
我覺得YouTube都可能有source 比用戶聽吓唔同sound level。
最後修改時間: 2023-02-11 14:20:16 - #8 [tonywong], 23-02-11 15:03can i use it between source and amplifier? then i don't need pre-amp
i almost use same volume level all the time - #9 [homan8577], 23-02-14 17:56What about model: standard / for source?
How to choose between these two options? - #10 [mcc_2001], 23-02-14 18:51Those attenuators work between your source and load (input) impedance, both attenuation and sound performance will change on different setups.
- #11 [七仔], 23-02-23 17:18#4 多謝師兄推介，試了。細節沒有少了，動態也無損，現在細聲點也可以聽齊所有東西，低音也推了出來。好得。
- #12 [七仔], 23-03-07 23:16Rothwell 終於都試埋，-20db。不知道是否因為衰減太多還是不同廠的問題，Rothwell動態吃掉了一些，有D吽吽豆豆。還是Harrison Lab的 -12db 動態好好多，vol掣扭到什麼位置不太重要。
- #13 [NAF], 23-03-08 15:53我玩biamp、因為二部後级輸入靈敏度同輸出功率有分别、曾經用過衰减器, 效果不好、且常要因應每首歌不同的高低音去調節、現用K 無源前級效果ok
- #14 [johnsonha], 23-04-25 14:56我都入左Rothwell -20db XLR, 唔覺有負面影響, 反而提升明顯
因為我部DAC同前級個gain大, 搞到DAC行fixed out 個前級唔可以交大vol 過9點鐘...
相反DAC交-23dB 個前級先可以正常交vol, 但明顯聽到損失了細節, 人聲失去了感情...
就係見到呢個post甘就訂左返黎, 真係解決到呢個問題, Rothwell -20db 剛剛底消左DAC既23db, 而家部前級可以開大過10點, 而我部前級既sweet pot 係10-1點鐘左右, 人聲立即鮮活不少, 底音一浸浸出番黎, 呢幾舊水俾得太遲....... - 返回 ...
Too many gain of preamp ~ use attenuator?
rothwell attenuator? Thanks!
Put it between preamp and power amp
