Atoll CD30 CD-player
The CD30 is in a strict, branded design with a minimum of controls on the front panel. The transport mechanism (TEAC CD drive) is centrally located, with a high-contrast matrix display to its left. The information displayed on it, including CD-Text data, is quite legible even from a long distance. The digital-to-analog conversion is done by the dual-channel WM8729 processor from Wolfson Microelectronics. This is a modern chip with delta/sigma modulation and 24-bit/192kHz input signal support. The output stages are symmetrical using discrete elements. There is no balanced XLR output; there are only RCA output jacks on the rear panel of the device as well as coaxial digital output and USB (Type A) interface for external media connection. The device has some curious expansion possibilities. For example, for an extra fee to the CD30 can be installed FM-tuner card with a memory for 60 radio stations, which will save space in the rack and save you from having to buy another unit. The package includes a system remote control that can, in addition to the CD-player itself, command other Atoll equipment.
In the sound of ordinary CDs one is attracted by the confident dynamics, extreme openness and a high degree of expressiveness. I don't exclude that this effect occurs due to the non-standard level of the output signal 2.5 V. From the minor drawbacks we can note a small lack of specificity on the edges of the range and not too impressive in depth low-frequency register. Sound resolution (especially in the middle frequencies) is very high - even minor nuances of the phonogram do not escape. However, you can still notice a slight veil in the midrange of audiophile recordings of the highest quality. It seems to be worth experimenting with the interconnect and power cables. Among the evident advantages of the player we can also refer a spectacular construction of the sound space. The stage is incredibly wide and completely fills the listening room. Localization of imaginary sources in its central part is simply exemplary.
Through the USB port only playback of mp3 files with any bitrate is provided, so let's listen to them. Appeared changes, first of all, concern a sound scene - orderliness of images is lost and space is narrowed. Inevitable losses during encoding are also reflected in some reduction of natural midrange frequencies, but in general the sound character of the player remains unchanged.
