55# moonnight Moonnight. If I remember correctly, in one of the threads you mentioned about the Stax electrostatics headphone but after that I did not read anything more about it from you. Does this company still exist in Japan? It also made electrostatics speakers handled by Radio People.
Its headphone was the reference at the time. Its midrange was "no fight" for even very expensive speaker systems of the day. Merely buying this headphone and a nice little amp, the audio system was better than most that cost 30 or 40 times more. But its treble and bass was a bit lacking. Also it was heavy and demanded a separate amplifier to drive it, so inconvenient that I eventually substituted it by a Sony headphone, the one that I used in the Review of Carat Topaz DAC.
Did you own one and are you still using it?

61# francisleung
Stax 我冇錯係十幾年前曾經擁有,亦都係當時旗艦款式,但礙於當時只著眼家用音響,
而這個開放式耳機實際並未能於深夜使用(會吵著家人的),所以不久便放售了.
就當年而言,要用耳機聽小提琴,實際並無它選,印像中它的中高頻響應相當理想,甚至
一些數萬元級別家用音響也不能比美,只是低頻量感與親耳詅聽hi-fi仍有很大分別,
期後我有一領悟,就是耳機不可能做出那龎大低頻,原因係物理所限,就算做出低頻,也
是一些假低頻,所以要做取舍,要假要真自已選擇了.
至於你所提到高頻不足問題,個人則不同意,個人是認為它的高頻是好到不得了,而且
當配上更好的"膽"時,表現比很多十萬元級音響更好,只是少了因為空間內牆壁的多次
音頻反射,而做成的空間感.
耳擴方面,由於是靜電式,選擇也沒有了,但這不是問題,反正每款大耳筒基本也需耳擴,
原廠設定就沒有性挌與銜接的問題了,任何需要,換膽管便成.
到最後我只想說,用了它你的腦海便產生一種Standed,而這個Standed,實則很難找
其它耳機取代,近代的旗艦動圈耳筒我暫無緣接觸如T1,HD800等,難下對比上評論,
但個人仍認為以家用音響又或耳機音響,靜電式揚聲仍是個人最為喜歡的一種方式.

66# moonnight Moonnight. From your message, I more or less have an understanding of your requirement from hifi. As I mentioned in the Review of Carat Topaz DAC, I perhaps have stronger than normal liking of treble, I mean undistorted treble. In this respect I find most audio system lacking, even the 6 ribbon strips per channel in my main system. When I have my amps repaired (5 dead ones that I guess have their power transistors blew off) I will retrieve my Stax headphone and see how it sounds like in comparison with present day gear.

1. sorry 我誤會了

2. 唔係太明,小弟英文太不材,你是指你什麼東西有6條ribbon壞了( infinit speaker )? 那一部amp壞了五支功率管?

3. 你在用Stax? 已作收藏嗎?

68# moonnight Moonnight. It seems I did not make points clear enough.
I. I now use the main system that has 6 tweeter ribbons on each side (6 left and 6 right). They are Maneplanar, not the Infinity ones that you see in the photo contained in Review of the Carat Topaz DAC.
2. I use many amplifiers in the main system. 5 of them are dead but without them over a dozen are still operating. Without the dead amps, some midrange ribbons (Strathearn) are silent as well as the woofers, meaning the main system is only 80% up to standard. What I meant to say was that when I have the amps repaired in future, I will use one of them to drive the Stax headphone in order to see whether it is up to its proper quality or not. I do not wish to take out an amp from the main system for trying out the Stax because every time I change things, I blew up one or two amps. The Strathearn ribbons go down to low ohms that easily wipe out power transistors. Actually I have crossovers that filter out the fatal low frequency but they degrade the sound and every now and then I defeat them in order to get better sound and thus always run the risk of wiping out the transistors especially when I mistakenly unplug something or forget to switch off the system before touching the plugs etc.
3. I found the Stax headphone inconvenient and substituted it by a small Sony that works without the need for an amp whilst giving quite good sound when it is plugged into anything, cassettes and whatever. I have stored the Stax away and I understand electrostatics are affected by humidity in Hong Kong and therefore do not know whether it still works properly or not.

1. 那些圖片我不記得了,但原來francis兄也是靜電愛好者,這好說了,你會更易明白我說的.

2. 原來你係指一部份鋁帶壞了,甚至跌ohm令晶體管損壞,我有理解錯嗎?
    個人認為,若然你玩的是靜電坐地,很大機會會不太習慣Stax,原因是坐地多了一個反相訊號到後牆作反射,
    那層空間與立體感是耳機不能比美的,但如若只論樂器質感,Stax的高階耳機應可滿足需要而作為耳機主系統.

3. 如果只提潮濕問題,個人認為香港使用問題不大,用後放回防潮箱便成了.
    當然只談方便,Stax還算麻煩,但那麻煩對比使用靜電坐地,還算小事一件呢~

70# moonnight Moonnight. 1. I like the midrange of electrostatics. The Quad is the legend but it does not play loud and at least two should be stacked together to produce adequate sound and it does not have adequate treble (Mark Levenson stacked two together and added Decca ribbons for the treble). The best electrostatics I heard was the original Martin Logan in my old neighbour's house. But at the time this speaker system failed easily in Hong Kong (the Quad as well and the explanation was humidity) and purchasers soon got unsatisfied for various reasons and sold them. I never owned electrostatics speaker system except the Stax headphone.
2. Ribbons on their own, because of their construction, have low ohm (film of aluminum deposited by vapourization on plastic sheet or stand alone thin foil of aluminium that are surrounded front and back with magnets to get the push pull action of sound wave). Each one needs a transformer and usually the speaker manufacturer group two or three ribbons in series to increase the ohm load in order not to wipe out amplifiers (the Infinity Reference Standard speaker system group three Strathearn ribbons in series). I set up my ribbons one for each amplifier channel (still with transformer) to improve the sound and thus run the risk of ruining the amplifier. The Strathern ribbons do not go dead themselves (film of aluminium on plastic sheet and thus nothing goes wrong). It was the amplifier power transistors got wiped out by sudden and unwanted ohm drop caused by my mistakes, that occurred when I changed or plugged and unplugged things without adequate care. Ruining amplifiers happened many times and the Sun Wah repair man knows me well.

The moisture and humidity kills all those electrostatics speakers such as Quad, Martin Logan easily in HK.

73# jeff64hk You hear about the same cause. At the time I knew of two audiophiles wanting to sell their original Martin Logans, still working not dead, but Sun Wah, the second hand shop did not want to buy, not because of price but of foreseeable problem with the electrostatics. Now the Quads and Martin Logans are partly made in China! For the latter information, one may get from its web. The Quads electrostatics are still too "polite" sounding as I heard them in the 2009 Hong Kong Hi Fi show. When the Quads were handled by Radio People, I dared not ask them to play the Beethoven 9 Symphony at loud volume because I did not want the electrostatic cells to stick to the panel caused by large excursion and drop dead. The young man at the Central Shop was a very nice and helpful guy.

It's quite troublesome to maintain the electricstatic speakers to play at their best even though you got hi-end stuff like Cello/Boulder......and use of ribbons is the reason, like Apogee, they changed their design from full-range to hybrid, somehow to avoid a lot of problem.
