TC官方对于声音风格改变的一些回答:http://www.gearslutz.com/board/1253218-post2.html
"The BM6A uses discrete pairs of MOSFET output devices (IR540-IR9540) . We have not seen the insides of a BM6A MkII or BM12A yet, so we don't know what the amplifier complement will be.
But the bottom line in this: We have heard the BM6A MkII and the sound quality is amazing. Critical listening tests conducted in Denmark showed the MK II to have a superior sound quality, and while it may not get quite as loud as a BM6A, many test listeners preferred the MK II's sound quality. We recognize the BM6A is a studio standard, so it is not being discontinued. Both the BM6A and the BM6A Mk II will stay in the line for a long time, so your client does not have to go elsewhere.
There are many audio enthusiasts who believe that MOSFET amps sound better than non-MOSFET amps. I think I'll stay out of that argument, but I do think the new Dynaudio models are just as exciting as the original BM Series. They have a modern look and a modern sound and while they cost less than the original series, the performance is top quality, something Dynaudio engineers are quite proud of".
“老6A使用一对MOSFET功放,新6A MKII和12A没有,不过新6A MKII的声音依然惊人,丹麦本地的试听测试来看MKII同样具备顶级音质,虽然没有老6A大声,很多测试人员更喜欢MKII的声音。而且老6A不会停产,6A和6A MKII讲会同时共存很长一段时间,爱谁谁。
很多人以为采用 MOSFET就比非MOSFET的声音好,我并不认同,我认为两者同样出众,MKII 拥有更现代的外观与现代的声音,而且价格便宜不少,表现依然惊人,我们的丹拿工程师对新6A非常自豪。” http://www.gearslutz.com/board/7171521-post8.html
