贴几个audiogon上对比360第二代和400的发言：

一、
I spent extensive time listening to the new Spectral DMA 400 mono-blocks amplifier at my dealers show room. The 400s were connected to a large Magico speaker,Spectral pre-amplifier and Spectral reference CD player.

The DMA 400s sounded excellent but not very different and surely not better than the DMA 360 series II. The DMA 360s consistently had a fuller bodied sound with similar detail, sound stage and resolution. This sonic difference was reproducible with any music genre or CD I had listened to.

My conclusion is that the DMA 400s are an excellent product, but if you have the 360s II - it will be waste of money to change, but I encourage you to listen for yourselves.

结论：400相对于360第二代提升不大。

I typically do not A-B components and just let my music play. In 99% of the time this is enough for me to study and learn sonic signatures. This time I actually had to A-B the 400s against the 360s as the sonic differences happen to be very subtle.

As the DMA 400 is based on the new concept of the DMA 260 with its different sonic characteristics, I expected more noticeable sonic differences - but they they were lacking.: the 400s sounded very close to the 360 series II.

If pushed to comment, I would say that the 400s might be more refined in the lower frequencies, however the overall tonality, soundstage, focus, macro and micro dynamics are similar. The 360s have a bit fuller body. Overall I would say that I liked the 360 better.

I concluded that although the DMA 400 are so called the new reference, in my mind it does not justify the increased cost and surely the extra cost to exchange a fine pair of 360s.
结论：400较360第二代在低频解析上稍好于360第二代，但音色、声场、定位和大小动态非常近似。升级意义不大。

I received my DMA 400 amps two weeks ago, which replaced my Spectral DMA 360 series ones, 11 years old. There is no question that these are much better than the 360s, which were extremely good. Over the past 6 months I have upgraded all my spectral equipment, including pre amp to ss30 series 11 and cd to the 4000sl. All power cords to audience Au 24 and ar6tss. The 400s have better defination, inner detail and I can definitely hear the difference, in short they sound more like music. Never hearing the 360 series2 I can only say that these are terific and can not imagine that after break in, about 200hrs, anyone should be able to hear the improvement.
结论：400比360第一代在解析和音乐味上有非常大的提升。

总之400肯定好于360，但貌似好于360第一代比好于360第二代更多，如果手上是360第一代可以考虑调查下。

好，谢谢！

谢aml1兄的详尽回复，同时请教一下，安铁龙烧保险是在什么状态下烧的

通常都是开机电压过高冲坏的，要注意的是烧保险跟质量，设计都毫无关系。贵丰的保护线路真的做得太好了。贵丰是让人越听越爱的扩大机！

哦，谢谢aml1兄提醒，我会注意的

   

Spectral DMA-360 Series 2 单声道后级推世霸至尊名琴不知道够不够力？

SPECTRAL功率很足的，我听过360S2驱动魔域旗舰U2完全不费力，

推9800可以否
