DAC with signal delivered this way sounded so incredibly natural. I repeat it again and again (to be precise – for the third time), but I can't forget the sound I heard in Jacek Gawłowski's mastering studio. It was incredibly natural and believable. CEC offers a very similar performance. It focuses on delivering particularly rich, full sound, on texturing, on the maximization of "firmness" of the sound. It is vivid and active while having no hint of any digital artifacts in it.Its tonal balance is shifted downward the band, at least in comparison to most other digital sources, and it is one of the foundations on which the sound is constructed. It is so in part due to the belt-driven transport, but DAC also promotes this “vision” of the sound. With the Audionet as transport sound was a little lighter, but mainly not so deep - and I don't mean the sound stage, which I will discuss in a moment, but the depth of individual instruments, vocals, reverbs.The way that CEC system presents the physicality of drums, bass, trumpet, vocals finally, is simply incredible. It's very uncommon in the context of audio in general, not only for a digital player. In this respect, this performance was very close to the sound of an analog master tape. This is not the same sound, it is simply not possible, but among the devices for audio playback only two digital systems - dCS Vivaldi SACD Player and Ancient Audio Lektor Grand SE CD Player - and among turntables primarily TechDAS Air Force One offered similar attributes.
