我的 Rogers LS3/5a 历程

呢度耐唔耐有人谈论L S3/5A，相信钟爱呢对喇叭仔的同好数量不少。不如由我牵个头，霸番过地盘讲LS3/5A。识多些朋友，交流经验，人生美事也。LS3/5A并非完美，有缺点，但我对吨Q几年，钟爱程度一直有增无减，可能烧过笼，烧坏脑，依家搅到屋企有17对，两年前搅埋古董胆机。令度我不能自拔，欲罢不能，欲仙欲死........
我不讳言当初是受音响杂志的影响购入第一对Rogers仔，17年前，购自旺角音响，呢对Rogers仔背皮贴住15ohm招纸，若干年之后先知坅Y11ohm，价钱3760大洋。首先各位可否分享点解拣葲S3/5A 陪大家度过开心或唔开心的日子呢？

以上是好友姜兄于 2003 年 6 月 7 日在 香港 Revieww33 LS3/5A 同好会的创会词，有感 3/5 仔近年日益珍贵，回归中国大陆也越来越多，致价值日益升高；小弟年青时对 3/5 仔一见钟情，奈何当时身旡分文，消费不起，只有望梅止渴的份儿。

直 至 1998 年一次逛商场时又给我碰到有3/5仔的踪跡，价钱是港币 5,500 当时觉得机不可失，便马上把它买了下来，后来才知此 3/5 仔是 11 欧的，记得当时用石机，用单端 845 胆机推它都不好声，心灰意冷，心想 3/5 仔亦不过如 此，如是者过了好几年，在一次买卖3/5仔的交收中认识了姜兄，時为 2003 年，在他家中聆听 Leak + 3/5 仔的驚为天人表现后，从此便踏上一发不可收拾的 3/5 仔搜集之路，最多時也有 15 对之多，其中的苦与乐，在此拋砖引玉，望各同好也一同分享。

The forgotten king,B&W 801 matrix s3

B&W 801 S3

B&w is no stranger of making quality speaker. Abbey road studio use a lot of b&w speaker especially the flagship model like the 8o1 series to mix classical music.

A pair of 801 series 3 has been maul to my buddy room and it’s time to listen to this king again. Previously this king was the flagship model of B&W but later replace by the nautilus and now the diamond series.

The associate gear for the night was Jadis JA80, Clone MFA pre and Mark Levinson Dac and transport in a medium size room. The speaker is standing on the original puck

Upon listening the impression i get is very clean, calm and gentle character. Music seems to be slow down, giving more time to enjoy the music. Mid is transparent and with sparkle high but the main problem seems to be the bass. There not much mid bass with very loose low bass and lag behind the excel mid and high. I heard some very weird sound emitting from the bass. The sound is more compose when we crank out loud

There is some uniqueness.The circle area is actually hollow.I heard mid low emit from there.We try a torch light buit cannot see anything as the light can't go through the cloth.

Maybe the power amplifier need more juice. We should give more time for my buddy as the speaker is only landed on his room 2 weeks ago.

Long live the king!.

Philips CDM4 Laser Head (2)

很多朋友都有疑问，Philips CD Player这么好吗？Philips 是lesar光头的祖先，研发出来的CD光头不是现代的光头能比下去，Philips lesar光头从CDM0开始至现代的CD pro（CDM12.xx)，不断的改进和降低成本，CDM3和CDM4 pro应该是成本最高。CDM3出来都用在一些高精密的仪器和高级的音响CD Player里，如Studer A730、Philips LHH2000和一些高级CD Player。CDM4 pro是用于高级CD Player。

CDM4/19是普通民用版本，只用在一般的中级CD Player，Philips CD Player　CD4xx和CD6xx大多数都是这个光头，Philips为了再降低成本就研发出CDM9。

CDM9可说也是最耐用的光头，很少出问题，我的CD930用了十多年都没出过问题。

Philips CDM4 Laser Head (1)

Kenneth Lau开了这个BLOG，给我们这些发烧友有机会在网上发表一些个人玩音响心得，先来看看我个人的音响系统：

CD PLAYER 都是普通Philips有

• CD880 （用CDM3光头，原来的CDM1MKll已经完蛋）
• CD650 （原来的CDM2已经完蛋，可玩CDM3光头）
• CD624　CDM4光头
• CD930　CDM9光头
• CD473　CDM4光头

DAC ：CS8414 + WM8740 (自己设计＋DIY)

Pre Amplifier ：Matisse Ref （DIY)

Power Amplifer ：半个Marantz 9 (DIY)

Speaker ：Rogers LS3/5a 11R + Foundation

在这几部Phillps CD Player里，CD880算是一部很好的原音，可惜的是到我手上原来的CDM1MKll已经完蛋了，未能听听原版的CD880声音，在还没拥有CD880之前，我已经在试玩Phillps的CDM光头，先说说CDM4光头，CDM4可说是一个很不错的光头，声音相当的稳定，比起CD pro还要稳定.

CDM4加上CD压更加稳定，控制力、分析了、音场的表现都进了一大步，玩CDM4光头的朋友可试试找个CD压来玩玩，一定有意外的收获，下回再聊聊.

Infected! By h1f1 virus (3)Speaker & Cd player

Speaker

I search through PASAR ROAD KL and look at all the possibility. Car audio, tv speaker driver but at last settle on a pair of rm20.00 national 8 inch full range.

This a diatone P610mb.I like this fullrange.

This is excellent in term of price/ performance. After a while the upgrade bug keep bothering and I decided to buy speaker after reading too many hifi magazine and none of them mention full range and diy speaker.

From there I have owned more than 10 pairs of speaker like mordaunt short ms10, Aliante spazio, chariot syntar 2, rega el8, klipsch tangent , goodmans maxim,jbl,b&w….etc and I just can’t stop buying more and more.

At that time mostly I restricted to buy middle to entry level bookshelf speaker. I still renting a room in KL and I only dare to dream to own a big speaker.

Source-cd player

Now come the source, I bought my cd player blindly consequences on rely entirely on hifi magazine and the look alone. The pioneer pds904 with the cd put upside down is really macho to look at. It spin the cd like a turntable.

The tweak that I have done to the cd player is:
1) Change the power cord
2) Damp all the electrolytic capacitors.
3) Shield the transformer , this cd palyer use 2 transformer and I think 1 is for digital and another is for analog.
4) Replace the cd mat. This is 1 of the radical tweak and it is not easy.I replace the cd mat with a cork mat. You can diy a cork mat but it is a hard wok.(Who say diy is easy?) First you have to sand off the thickness of the cork sheet until it is the same thickness as the original mat.

Later when you get the desire thickness cut out the shape and just put in.

The thickness must be balance all the way or the cd player may fail to read any cd’s.(Other may use others thickness but adjusting the lens but I did not how to do this).

You don’t have to use any glue as the cork is automatically stuck at the place when you put in. Please don’t throw away the original mat in case you may need to use it back.

Even after I tweak the cd player I still don’t like it .(maybe I didn’t try hard enough)This is the consequences of reading too many hifi magazine and buy solely base on recommendation......continue to revolution.

Infected! By h1f1 virus (2)Amplifier

I’m still an student then but start equip myself with knowledge from books like What hifi, stereophile, any thing at the book store. After a few years I have decided that I must get myself a valve system.Cash is tight then so my first equipment I bought is AMC CVT 3030A(2nd hand).You can’t believe the goodie in this amplifier. It actually use Siemens el34 as the power tube. The pre is solid state.

The el34 tube is solder directly to a PCB board and when the power tube die, we have to change the whole board (Later version use sovtek el34 with tube socket).The funny thing is this amplifier cramp a pair of fan inside the amplifier. The connector that supplies the tube heater will always give problem. Just bypass the connector and solder directly to the pcb board will eliminate this.

Tweak

I’m just started my hifi journey but I have started to open up the equipment.

1) Disconnect the fan(The tube is able to stand the heat as long the ventilation is ok)
2) Rewire the signal wire (the original signal wire is using zip code wire) I only change the cd input wire.
3) The output wire change to branded speaker wire (wire from the output transformer to the speaker connector)***I send in to the dealer and they charge me rm100 for this-Now you know how green I am at that time.
4) Damp the chassis especially the rear panel. (this panel ring a lot)
After the tweak guess what! I don’t have speaker and cd player. Luckily I have a computer and i use the cd-rom headphone output jack and a splitter interconnect and voila! the source problem is solved.

At that moment I have nothing but a Toshiba mini combo speaker. The mini combo only cost me RM120 and you can imagine how cheap the speaker is. A brief try out give me a real surprise. It actually sound ok.

So immediately I open up the speaker to damp the cabinet. Doing this i found out that this speaker is actually using a single driver. Hmmm…single driver and tube is always a good synergy ( this has always in my mind after this incident).

This make me happy for a while and I start search for my speaker…continue.
