師兄你好！
我部舊泉早前已賣掉，
泉二係全價買入的，

Hi Brother TChan,
Have you gone through the Spring II yet? What's your listening experience? Please share with us all. Thanks!

師兄你好，咁就講下初步聽感。

按我之前玩老泉經驗，如果7x24長㷛，一個星期後聲音會開始穩定，再多一個星期基本上就全熟。
泉二唱咗差不多一星期，進度似乎也是差不多，但當中有個情況很不一樣，第一天，第一天開聲就是沒有之前老泉聲音粗糙沙石的情況出現，我聽了一整天感覺都非常舒服，第二天聲音開始有點模糊及不太穩定，但可聽性仍然有。

由於從老泉到泉二中間我換了不少缐材，所以好難直接比較，我只能用一直原用的DAC作參考，嘗試比較一下。
有三方面表現個人特別有感覺：
（1）質感 - 播結他出來的彈跳力，打起鼓上來嘅實在感，似乎係之前老泉俾唔到的；
（2）音場 - 表現明顯更闊大、更穩定；
（3）速度 - 老泉一路俾我感覺聲音速度來得比較慢，每次播大型樂章時總覺少了一種刺激感，這方面泉二也有不少改善。

就咁先，等㷛好下次再講。

師兄，

Are the RCA and XLR outputs of the Spring II with the same voltge of the old Spring? Or the Spring II is a bit higher?

咁呢方面我就無留意喎。

The higher of the outputs, the greater of the dynamic and wider of the sound field could be achieved.

請問用 Holo Audio 泉的C兄，
覺唔覺人聲是比較矮？

Absolute phase 反轉咗就有咁既情況出現。

將［左右］ 聲道丨 喇叭 嘅 ［正負］一齊反轉聽下就知道 個absolute phase 係咪反轉咗.

As my preamp has a phase invert button, I couldn't identify whether the phase was in or out by switching the button repeatedly.

謝謝 Momei 兄提及的 absolute phase.
這裡有解釋 :

令我更震驚的是這裡有兩條短 sound track, 一條係 absolute phase, 另一條不是.  Non absolute phase 那條的聲場明顯縮小.

Sorry 兩條短 sound track 是在這裡 :

Some DACs or preapms have a phase inversion switch. I do not have enough experience with these to pass judgment but I have heard that especially those using a remote, only change the absolute phase to some extent but  not 180 degrees. A thorough and proper change is to switch the terminals of both speakers.
You may wish to try again with a speaker-terminals change and use a large orchestral work with loud brass passages, for example, Tchaikovsky's Symphony 4, Copland's Fanfare for the Common Man. If you do not have these, the saxopone solo in High Life track in Jazz at the Pawn Shop 1 may also be used. The correct absolute phase would have the brass passages splashing towards you.
If you are still unable to hear the difference between the two opposite phases, perhaps your speakers have mixed dispersions and that would also be reflected in below par performance in image size, sharpness, placement etc.

整個音響系統的 absolute phase 有多個變數, 前後級所用的線路設計都有可能改變 absolute phase.  用不同後級聽電子分音的可能都遇過這情況 - 有些後級的輸入輸出是沒倒相的, 有些後級有.
每次試機, 換機時宜先多聽一輪左右喇叭齊反接.

DGG的碟全是反相。用它來測試最方便。

新漢陳sir 很有研究，他曾經列出一張表那間唱片公司的CD 是正相，那間的是反相。

咁啱嘅位師兄又講相位。

Some DAC, Streamer/Renderer and Pre amp all have phase switch.

Use Audio Compass 2016 can test the phase.
