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.
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😂

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!

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.

@@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。
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.

Nelson Pass 所有 class A 都唔會好熱 由 Threshold 到 Pass Labs 都可以玩二三十年都唔洗換電溶 今時今日 class A 機都熱手 唔洗諗啦
@@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 ??? Paul
@@user-rg7do3qp5u 認同,A 類因設計方式不同,使用電力最多,熱力也最高,事實上,市場已越來越少 A 類機,純 A 類的更少,也算是顯示出純 A 類真的不是必要,很多純 A 擴音機因為要附上一個巨型金屬散熱器,再加上變壓器也要加大,所以重量更是誇張。我們的一代可能還是對大塊頭的重物很喜愛,也許下一代如果還會玩音響的話,也不會再有這種很情意結式的追求了(國仁)
