之前听高人提过，说数字直连多数情况下差于靠谱解码器而后模拟输入，转载下内容：数字输入口的多采样率兼容性基本都是asrc凑活做的（成本和空间限制），导致显著劣化，而内置adda线路是固定采样率的天然同步设计，无需考虑采样率兼容问题。而模拟信号进8351以后AD/DA，这种同步短线路adda对声音劣化极小（做好了不会比模拟分频差），所以不要担心模拟进来被“数字化”，这不是问题，因为和外置dac完全不是一回事。
高人？只能呵呵了。跳大神装神弄鬼的不少，做出器材做出名堂的不多。
高人和真力工程师，哪个更高一些？其实这个不需要什么智商来判断吧。
真力工程师认为数字输入是最优解。
如果这个声音你还是不喜欢，那也就不必纠结真力了。名气再大的器材都有人不喜，发烧就是抓住自己喜欢的那一种音色不停意淫的过程
不但是真力，Adam也推荐数字箱使用数字输入。

[QUOTE=David Angress;12663836]ADAM Audio’s S-Series uses the Cirrus 42528 with a custom built output circuit which has specs close to those of the mentioned RME card. With the gain ranging that is employed, the specs are even a bit better.
Now, as to what sounds 'better/cleaner', that is a subjective discussion and the ultimate decision we leave to you.
With the digital architecture of the S-Series, if you drive it from an analog source, the audio is re-digitized as it needs to be processed by the Sharc, then is converted back into analog.
So your options are:
Digital source -> external D/A -> ADAM A/D -> DSP -> ADAM D/A -> Class-D amp, or:
Digital source -> digital in -> DSP -> ADAM D/A -> Class-D amp
Purely from an engineering standpoint, we prefer the latter. A few exceptions apply, such as if you prefer the particular sonic characteristics of your favorite DAC.
Pro digital in direct:
- no redundant A/D and D/A conversion
- lowest possible noise and THD
- converter circuits optimized, tested and verified for ADAM amplifier and loudspeakers
- loudspeaker was voiced and tuned for these DACs by ADAM engineers
With that said, the ADAM Audio roadshows that were presented around the US and in Europe over the past months all used the S Series’ analog input driven by external Prism Sound DAC’s. The participants semed very pleased with the sound.
I suggest that you do your own comparisons via your local dealer, or contact us and we will help arrange that for you.
