I have been listening to the Jeff Back “blow by blow” album for over 40 years in every format. I recently got the 45rmp Vinyl, it gives me the goosebumps I never had even I listened to this album hundreds of times.
This brought back to me a bit of memory back then in mid 80's. I went for an audition of this MF A1 and it sounded very impressive as I was desiring to buy a pure Class A amp. The following day I also went for an audition of another Class A amp at Excel HiFi, the Krell KSA50. The sound was absolutely stunning and irresistible, and I ended up buying it. Of course the price of the KSA50 power amp itself was, if I remember correctly, almost three times the price of the A1. Honestly, price wise I think the A1 was far more value for money then the Krell. If I had not went for an audition of the Krell, I definitely would had bought the A1.
Thanks for the report. Such a shame you did not visit Renaissance in rooms 501-506, best sound at the show from MOON by Simaudio, Nordost, Audiovector & VPI Industries. Next time!
First of all I am not an electronic technician, but I try to use my common sense. I understand that the class A amplifier generates a lot of heat during the operation. However, I would think that the audio electronic designers spent a lot of time and effort to stabilize the operation by minimize the heat being generated during the sound reproduction process. Therefore Accuphase, Luxman and McIntosh will not intentionally manufacture hot pots especially using transistors for designing Class A amplifiers.
@@feverSoundHK 好多Class D amp的確係缺點多多，我有對LS50W，近場 皇帝位聽幾唔錯，但大啲volume或者坐遠啲就好唔掂。但如果識得㨂，有好多好嘢。PS Audio個CEO Paul McGowan有比較過Class A, Class AB 同Class D嘅意見，我覺得講得好中肯。10至15萬以內預算內玩Class A amp，不如買2部 Class D玩bi-amp推對好啲嘅喇叭，點都玩得好聲過Class A single wire。
國仁前輩，好多時我都有聽你嘅分享。不過我就冇任何朋友可以請教音響上面嘅問題，因為我唔喺香港（身處地新西蘭）沒有身邊朋友可以問到有關音響嘅問題。早幾年我買咗一部rotel RA-1570 ，之後喺第二間舖頭買咗一對坐地喇叭， kilpsch RP260F. 可能呢對坐地喇叭係比較適合家庭電影音響，我想問吓你有冇意見有咩喇叭比較適合，價錢商議嗰種。 其實我連屋企一套小型嘅Yamaha音響，出嚟嘅聲音俾依對大喇叭同台rotel ra1570 夾出嚟嘅音,仲優勝。 所以我問吓你會唔會有咩建議，係咪要配某類型嘅喇叭，效果會好好多。 請指教一下, any other way to contact u ???

A nice entry for Class A amp!
我部1987年A1仲係度
當年買$3200
在銅鑼灣原音買
部機咁細做class a 25w極有部保留...不過勁like佢佈局，大大塊鐵板燒兼埋外殼，有姿勢有實際。早廿幾年前都執過部二手玩過，著機果時......最鐘意得閒無事摸吓佢...辣吓手...好過癮😂
我記得1990年用差不多$3000買左1部 .當年已覺得十分正.
係三四千左右，但都唔算平，果陣買部VHS錄影機二千幾，都可以做24個月分期（國仁）
@@feverSoundHK 算平啦，買部LD Player 或者AV amp都貼住1萬，買部Mot記水壺都2萬。

A1s簽名版跟X10d到現在我還在使用中,想要更換電子零件來更新加升級!
如果可以揾到 Aura VA40 rebirth 比较更正。
復古機配少年時代既歌，好懷舊。
國仁哥，片中的 msb discrete dac 有沒有機會評測？

價格非常有競爭力
同 Nait 50 的價位比較，呢部的確係克制些
Please review the ATC SCM 19 😊😊😊
終於見到你做呢部機嘅review啦， 期待廠方用現今科技去改良原版嘅缺點
我諗最大分別係唔再用龜殼，因為龜殼真係可以熱到有燶味，小弟以前用過 Electroconpinet ECI-3 入面個龜殼都試過熱到部機自動跳掣，而家轉用大路嘢，我諗點都好啲。不過，如果我用，我個人都係會買個無刷散熱風扇仔對住個機頂吹（國仁）
@@feverSoundHK Power管嘅改動真係幾需要嘅， 原版用嘅 2N3055 個spec唔係好勁， 不但輸出功率受限制， 而且工作得幾辛苦吓㗎。 提外話， 以前砌機年代重可以買到嘅Motorola power管確實係幾好聲嘅。

多謝國仁兄介紹，你覺得推唔推倒B&W 805s 呢？
都係果句，近場聆聽中音量會較好發揮，而響25瓦射程範圍入面會好正，但一出呢個範圍就見樽頸（國仁）
多謝解答😉🙏🏼
呢部機我好記得 想當年喺屋企如果唔開冷氣 musical Fidelity 簡直熱到煲蛋 可以睇下隔咗二十年之後 有冇進步過
一樣咁熱，因為之前果部復刻「進步咗」反而不受歡迎，復刻，就係要連「好熱」呢一點都復刻才似樣（國仁）

A2無咁熱，聲底唔錯，GOOD CHOICE，唔知會唔會有復刻版！
@@kamtongwong9663 A1 同 A2 果 spec 差好遠
Class AB我都嫌嘥電，買都㨂啲Class D amp 。Class A，80年代就好正，而家懷念吓就算。
每種放大方式都有其優劣，各人都有自己喜好，表達了意見就好，不必講到「RIP」咁盡
@@feverSoundHK 引起誤會，唔好意思。RIP唔係話人，自己以前都好鐘意Class A amp。隨著技術進步及聽力下降，幾年前睇完你哋review Marantz PM-10，然後就買咗部，都聽唔到Class D有乜唔好，當然好多人唔鐘意，原因相信有好多。節省能源已成為普世價值，覺得Class D 已經係必然之選，所以Class A喺我心中已死，講佢 RIP表示功成身退。當然有好多人仍然喜歡Class A，呢啲係個人選擇，我冇半點異意。正如有啲人屋企都堅持用鎢絲燈， 大把人仍然用菲林，仲有人用緊手寫電話簿。
不緊要，你說的也是，有些人不明為何對Class D類擴音機恨之入骨，但其實此乃大勢所趨，而且好多D類擴音機也越來越好聲
@@feverSoundHK 好多Class D amp的確係缺點多多，我有對LS50W，近場 皇帝位聽幾唔錯，但大啲volume或者坐遠啲就好唔掂。但如果識得㨂，有好多好嘢。PS Audio個CEO Paul McGowan有比較過Class A, Class AB 同Class D嘅意見，我覺得講得好中肯。10至15萬以內預算內玩Class A amp，不如買2部 Class D玩bi-amp推對好啲嘅喇叭，點都玩得好聲過Class A single wire。
睇佐咁多年，从来冇睇講過關於Rotel 牌子的擴音機。
當年我升级，就是 A1初代 與Rotel 前後级二選其一，試聲後選了Rotel
@@shingwong6449 我宜家用緊舊款Rotel 推B&W 600系列座地，打算買1582mkii系列配700系列座地。但冇見人講過Rotel.
仲有 Bryston
當年係旺角六千幾買咗部A100X，用咗廿幾年, 係好夠力聲好暖, 但 volume制成日沙沙聲, 同埋我覺得部機左右立體聲分隔度好弱, 好似聽緊mono咁
我也有這情況出現
MF 早年前級設計問題通病，會漏少量直流電導致volume制好快壞，換新volume制可解決但一段時間後又壞過，必需mod前級才可長遠解決，可google有不同教學。

國仁前輩，好多時我都有聽你嘅分享。不過我就冇任何朋友可以請教音響上面嘅問題，因為我唔喺香港（身處地新西蘭）沒有身邊朋友可以問到有關音響嘅問題。早幾年我買咗一部rotel RA-1570 ，之後喺第二間舖頭買咗一對坐地喇叭， kilpsch RP260F.
可能呢對坐地喇叭係比較適合家庭電影音響，我想問吓你有冇意見有咩喇叭比較適合，價錢商議嗰種。
其實我連屋企一套小型嘅Yamaha音響，出嚟嘅聲音俾依對大喇叭同台rotel ra1570 夾出嚟嘅音,仲優勝。
所以我問吓你會唔會有咩建議，係咪要配某類型嘅喇叭，效果會好好多。
請指教一下, any other way to contact u ???
Paul
Paul 兄，我估計而家 Rotel 推 Klipsch 會較為粗聲，因為 Klipsch 個號角靈敏度非常高，而喇叭調聲亦傾向高速，Rotel 推力又偏大同樣也是有點不夠幼細。如果想換，換事旦一樣即可，換邊樣其實係由自己決定，Rotel 其中一個可夾之喇叭是 B&W，亦可考慮 Wharfedale 或 Elac 不貴的那些（國仁）
