Absolutely transparent, the SE-P900 does its job without ruining the basics of the signal it is fed with :

”The initial stage is a junction FET cascode connection differential amp with constant current source. It reduces the high range distortion resulting from non-linearity in the FET feedback capacity, because of the high input impedance and the cascode connection. The FET uses a dual cascode connection with excellent pair response to suppress temperature drift.

The second stage is a Miller current loaded differential amp composed of bipolar transistors, which provides high linearity response and power rejection response.

The final stage is a pure complementary emitter-follower SEPP output which provides low impedance output and high linearity response.
The buffer unit circuit allows 100% NF, and is employed as gain 1 (during DEFEAT in the equalizer stage) so there is almost no deterioration in sound quality.

五輪真弓~歌名"一葉舟" 歌詞意思，似是在大海裡隨浪漂泊湧流。歌曲是收錄大碟專輯‘’殘之火‘’刻在side two the last track。自己特意揾7吋碟聽。摷番早前曾翻錄卷帶及7吋碟。睇回log book，當時用既器材Nagaoka cartridge MP-500 及Ear 324 phono amp，tonearm 係SME M2-9。

dlld,

Thanks as I now know the name is "一葉舟". You recorded with tape and I had done with digital!!!

Traitor!!!

Hi Chi,

如果當天我有閒置心情，坐係sofa聽下帶。回味下自己的作品。!!!

今日中午有點眼瞓，最後播返隻 Frankie Goes to Hollywood 的 Relax 醒一醒神！
在 EQ 特別 set 去 Blend 及在 15Hz -2db.

正如說明書所講 “BLEND is the same as IN except that the low frequencies are blended below 40Hz for tighter bass…”

真係幸福可以喺全世界最繁忙嘅城市下午玩eq聽音樂...

Haha

最近不斷尋找我錄咗一餅reel 2 reel for. Kind of blue.... 其實我製作個好多次但係這一次最終成功.. EQ match the tape formula..... 嘩真係sound stage 闊咗 so much.. Layers with so define front to back distance.. 每樣嘢都玲瓏浮凸動作明顯...
. All because of some EQ... 忘記咗當天係用邊一部eq.. 肯定嘅就係嗰部eq已經唔喺我手上

Have a great day !

喺呢隻碟 Stan Getz 支 tenor sax 有點冰冷 …加點溫暖先 500hz +0.5db & 25 kHz -1db.
