多謝師兄分享

聽聞momemtum mono可以upgrade上新款m400

fs10945

1. 同舊代理買都有得升級？
2. 如可以升級，要多小錢？

koalakoala

外國講法mono upgrade us$15000
最新消息stereo s250 upgrade us$7500
未知香港代理安排

請問各同好的momentum stereo amp 是否直插牆，還是在電處？

又請問開amp 後， 在speaker 的tweeter 會否聽到很細的deeee 聲？

Many thanks c hings

直插牆，力水好，也可在孖牆版加簡易電處像shunyata vemon defender 一類
要入電處，最好與訊源電處分流，還要用大電流種類像isotek titan, shunyata cyclops， 不過效果沒有訊源顯著

沒發覺開機tweeter聲

Thank you!

Seems like I'm the only one with the faint electricity tweeter sound

Need to find the cause!

我部 Integrated 開機時有 BOP 一聲, 我都唔知點解, 我以前部 cyrus 都是一樣, goldmund 和 nagra 都冇這個情況,所以應該冇得被免. 不過我懷疑同電壓有関.

可能同 zero feedback amp 設計有關，Cyrus x300 signature , mark levinson 都是，但 Dan 就不是完全 zero feedback. 只是 low feedback. 所以應該同 circuit design 有關係
不過習慣左就唔驚驚嚧

It worked!

I bought a Shunyata venom defender and the noise decreased 90%

Some forum oversea also mentioned about Dan mono block has a buzz sound and the buzz disappeared after the defender

I plan to get the second defender to see whether it can further improve!

Btw

Any one sent their amp back to upgrade to m400 or S250?

得閒要問吓代理……

我套momemtum前後又無Bop一聲，我開機次序由CD>前級>後級

chuck

我有用 Shunyata PS8 + defender + Nordost QK1 都重有 BOP 聲，無論開 DAC 或 Momentum 先，所以算罷了。

今日問左代理，香港Momentum 後級無得升級去M400，只可以賣左Momentum，再買新M400

I've asked agostino company in person

You can send your amp back to them ( book a date first )
And upgrade

The cost ( without shipping) is us $7500

咁擺明新代理不負責任，只求新生意，目光短淺

I wonder about the costs of shipping might be to and from USA
