我用呢個牌子就冇聽聞過，其他嗰啲師兄自己搵吓資料啦！

Not the LS or floorstand speaker. It's a SWAN big bookshelf speaker, its around 13k and the model should be M3+ (not very sure). It always sold out so may not be displayed.
68 is a power amp and need a pre amp to drive. I mean u can ask him to use it to test different types of tube for u so that u can decide which tube is best suite for u.
你都蒲埋頭！

細仔出咗細放緊假，餵緊夜奶又見知小小咪答句咀law. 錯你要話我，唔好等我唔知定害咗位ching{:6_147:}
你陪新機玩成點？諗掂換邊對喇叭未？
我啱啱買完DAC，會再儲錢買喇叭，不過都要一兩年後Lu{:6_198:}

68 is a power amp, 88.3 , 18.3 and 76 is a intergrated amp. 68 need a preamp to drive it and intergrated amp can drive without a independent preamp . Intergrated amp has a built-in preamp but may not be better than a individual preamp. Of course, adding a individual preamp is good but you can use a intergrated amp first and then if you think adding a preamp is good , you can buy one to use it. Sound master can change the intergrated amp to power amp if you turn the volumne to 12

好鬼幸福{:6_196:} ! 其實我熟佢啲線多過啲蛋,不過照計以樓主嘅情況我呢部 18.3 WE 版或者 V3 版都夠佢玩,因為呢兩個部版應該係最夠力！

多謝C hing意見，其實我的聆聽空間只百多呎，用的只是Quad1 2L2書架喇叭。我明白一枱合併機暫時應該夠我玩。只是現在試完18.3又等peter所說的加强版18.3。(不知道加強版18.3是否avlam師兄的18.3WE 版) 其次我知道88.3可以換EL34膽玩人聲或其它。再者將來可以加300B前級配搭在88.3。只可惜現在没有88.3試。所以只好下次找peter加前级試68。另外請問各師兄們300B+76 或300B+88.3有甚麼見議。

i prefer 300B + 76. Since your speaker is easy to driver, so it is good to use 300B+ 76.

For your information, I am using 9 + 68 + Quad 12L2. I feel quiet satisfy with vocal. However, for symphony, it is not detailed (dynamic) enough for me even I upgraded the jumper, sc, pc, tube. As discussed with other Chings here, it should the speaker not good enough and so cannot give the full performance of the preamp + power amp.
I think your case is similar to me. if you have no plan to upgrade your speaker, I also agree with AV Lam Hing that 18.3 may fit you most at this stage. You may also discuss with Peter to tailor made one for you so it can play symphony well.
You may also ask Peter to use 18.3 to play with the 3 SWAN speakers and you will understand better what I mean the speaker limitation in my case

師兄, 大家一齊研究吓咩叫做單端同推挽
接触胆机的朋友经常会听到单端和推挽这两个名词，不少商家也常常以这俩名词来推荐自己的产品，今天我们就来谈谈什么是单端和推挽。
单端和推挽都是胆机后级常用的两种电路形式。其中单端是单端放大的简称，也叫单边放大，它的工作原理就是只用一只放大元件（或多只元件但并联成一组）完成对信号正负两个半周的放大，而且只能采取甲类工作状态，这么做的优点是非线性失真小，缺点是输出功率小，效率低。因为失真小，同时在工艺处理上复杂程度较高，因此单端这种电路形式多数是在高端机上使用。
推挽则使用了两组放大元件，一个远见的电流增加时，另一个的电流就减小，二种状态轮流转换，好像是一个在推，一个在拉，共同完成电流输出任务，所以有推挽之称。这么做的优点是比较容易获得大功率，效率也高。但缺点同样明显，由于推挽的工作方式是一种叠加方式，因此不可避免地存在失真。相比单端而言，推挽电路在中低档机上用得比较多。
既然如此，是否意味着用单端就一定比推挽好呢？老猫认为这得分情况而定，毕竟听音本身就是很主观的东西。有人认为好的，就有人一定不以为然。因此在单端和推挽两种电路的选择上，建议大家还是用自己的耳朵去收货。但有一点是可以明确的，如果大家在购买胆机时遇到一个声称自己是单端电路，而价格又低于推挽电路的机器，那就一定得小心小心再小心。
我用緊MC368B 902 A類, 我同老闆都覺得好聲D{:6_193:}
原本88.3係一部非常值得推薦的合併機, 但最敗筆是她不是用膽整流, 用膽整流好玩好多.

我用緊88.3，幾好用，再加埋前級no.11 用300B 膽，聽人聲有韻味，聽大棚野88.3 配埋KT88 膽簡直一流！
