Spyder hing 想請教－下 小弟現在用cyrus2作為後级推Dali MM2，想嘗試轉用303 會否比Cyrus優勝？

QUAD 既缺點。。。
首先係既設計，由QUAD II 起，一直都是compact size. 唔打得都睇得是做不到了。
303 的體積跟 II 又幾乎一樣，我要幾年才能接受。
405的散熱片竟放在前，有冇搞錯?
直到34，306，606才出現比較容易接受的外觀。

知乜就講乜啦! 不過我當然想知quad 嘅vintage amp 多D啦!

舊 (made in England) 定 新(made in China) 先?

MIC 就全無認識。

各ching好!

不如大家轉一？方何, 究竟quad啲機有乜弱點,係比唔上其它機呢? 例如有味精? 低音冲撃力唔夠? 高音不唔幼細?

小巧不失威力－Quad Artera Play CD唱盤DAC與Artera Stereo後級 - U-Audio 試聽報告
http://review.u-audio.com.tw/reviewdetail.asp?reviewid=1215



Artera Stereo內部採用Current Dumping（電流傾倒）」A/B類混合擴大技術。該技術由Quad創辦人Peter Walker所設計，1975年首次用在QUAD 405後級上，當擴大機為低功率輸出時，由A類擴大電路運作，若擴大機承阻下降，高效率的B類擴大電路就會開始運作。（圖片來源：Quad官網）

師兄:
QUAD Elite*** DMP ***是否弄錯
QUAD Elite DMP MONO vs QUAD PLATINUM MONO,

The Elite QMP is a by-product of the earlier 909 Mono with enhancements distinctly noticable in amplifier construction and circuitry, and is capable of producing an accurately balanced XLR Moreover; the new Elite QMP now incorporates 'current dumping' allowing for a cleaner, more versatile performance.

Specifications

General Description Mono Power Amplifier
Design Philosophy And Core Technology Current Dumping
Output Power 260W RMS, 8 Ohms
Gain 33dB
Frequency Response 10Hz - 50kHz (+/-1dB)
Total Harmonic Distortion ＜0.005% at 100W, 1kHz, 105dB (20Hz - 20kHz)
Damping Factor
Input Sensitivity (RCA) 845mV (for max output)
Input Impedance (RCA) 15 kOhms
AMPBUS Input AMPBUX / XLR
AMPBUS Input Sensitivity 2.0V (for max output)
AMPBUS Input Imedance 10 kOhms
Dimension (H x W x D) 184 x 319 x 312mm
Boxed Weight: 21,8kg
這是壹對超值的Power-Amp,本人試用過來推CELESTION 600 or SL6 ATC SP
有用不完的力有質感,效果非常滿意.有數位朋友現時都用這對QUAD QMP MONO POWER-AMP
品質不錯,已用了兩年有多.經常不關機,正常運作.

請問QUAD Elite DMP MONO vs QUAD PLATINUM MONO, 即台机音質幼細，三頻平均，有空氣感，訊變快及定位準，此两台机也是中國制造，質數如何，因輸出互數大，好怕容易壞机，維修麻煩，請師兄们分享用家心德！

Ray Ming mentions slightly about the low distortion of Quad Electrostatic speaker ESL57, the THD distortion figure of Quad amps might NOT be the lowest, but surely it is immune from unnecessary coloration or artificial additions......thanks to the feed-forwrd error correction topology of CURRENT DUMPING invented by its designer Mike Albinson

Quad amps still lingers on decade after decade

我是學技術，信科學的，並不迷信名牌。推介名牌，還是留待其他師兄來做好了。

鴨記公婆檔或華X賣的，就夠好了。原裝的膠木封裝電容，雖然網上還可買到，不過我修機的經驗，此電容易生裂紋，隨即乾漏，並不耐用。

電解電容衰老是有個過程的，在電容值下降和ESR升高的臨界點時，常會出現各種各式的奇怪反應。
