The German company MBL introduces the C41 model, which aims to transform the landscape of digital music streaming. This device integrates advanced technologies designed to deliver sound in its most authentic form, free from distortion and characterized by exceptional naturalness.

Established in the 1970s by Wolfgang Meletzky, MBL has emerged as a key player in audio technology innovation. Those who have encountered the Radialstrahler System MBL 101 X-Treme MKII loudspeakers, featuring omnidirectional diaphragms, at exhibitions are likely to have a lasting impression. While we may not anticipate a radical departure from conventional designs with the streamer, it still incorporates advanced technologies that promise to elevate audio reproduction. Initial reviews indicate that there is a great deal to be excited about.

The MBL C41 promises real highlights

The company designates its initial technology as True Peak, which addresses the issue of clipping in digital reproduction. Clipping occurs when the digital signal surpasses the converter’s limits, even if the signal values themselves do not exceed 0 dB. This issue primarily arises from inter-sample peaks that develop between individual samples during the conversion to an analog signal. The result is undesirable sound distortion, a challenge that many well-known DAC manufacturers, such as AKM and ESS, often struggle to manage. Typically, these devices simply truncate the signal peaks. MBL presents a relatively straightforward and seemingly effective solution through a technology that enhances the total modulation range by an additional three decibels, increasing it from 96 dB to 99 dB. This solution, while somewhat costly and requiring development beyond conventional standards, ensures that users of the MBL C41 will not encounter clipping. Consequently, even the peaks of the signal are accurately reproduced, allowing tracks released during the loudness wars—characterized by excessive volume—to remain clear and free from distortion.

Core Volume Control innovative volume control

A significant advancement of the MBL C41 is its Core Volume Control system. This innovative technology allows for accurate volume adjustments directly within the digital domain, just prior to the conversion of the digital signal into analog. The outcome is reported to be a purer sound transmission, eliminating the necessity for a separate preamplifier. While this is an intriguing solution, it does not alter the fact that bit-perfect reproduction is no longer achievable. Nevertheless, given the capabilities of modern chips in various industries, we believe it is feasible to handle a digital signal with a level of care that minimizes damage, staying well within the constraints of analog components.

Connectivity for the 21st century

The MBL C41 excels in connectivity options, providing a comprehensive array of inputs that align perfectly with its intended use. It includes S/PDIF (RCA), optical Toslink, USB-B, and AES/EBU (XLR). On the output side, it features both analog XLR and RCA, as well as digital XLR. This versatility is particularly beneficial if you invest in a high-end device for its digital transport capabilities and prefer to utilize your own DAC with superior specifications, which is a scenario that may unexpectedly arise. Regarding digital resolution, the DAC MBL C41 supports standard specifications of 192kHz/24bit PCM and DSD64. This level of support is sufficient for any SACD and the majority of high-resolution audio streams without issues. There is no pressing need to pursue higher specifications like 384kHz/32bit PCM and DSD 512, as seen in models such as the TEAC UD-507, or even the 768 kHz resolution offered by the recently reviewed Matrix Audio Element X2. It is highly unlikely that you will encounter recordings of similar quality. However, you may come across many recordings with improperly set volume levels, a challenge that True Peak technology can effectively address.

The streamer is fully compatible with UPnP, DLNA, and Roon Ready protocols, and it also supports Apple AirPlay. However, the manufacturer has indicated that integration with Tidal, Spotify, and Qobuz services will be available later this year through an update. Currently, the C41 primarily caters to users with local libraries and those utilizing Roon. It is somewhat disappointing to observe the trend of launching products before all services are fully integrated. While this approach may be understandable for more affordable devices like the WiiM Ultra, which also anticipates AirPlay, it raises expectations for high-end products where a more cohesive strategy would be appreciated. In this market segment, other factors are being prioritized, including design alongside advanced technical features. The MBL C41 excels in this regard, as it offers a striking visual appeal typical of the German brand’s products. It is available in four elegant color combinations: black/gold, black/silver, white/gold, and white/silver. Each 15 kg variant exudes a sense of luxury and is sure to enhance any Hi-Fi setup.

The user interface features a distinct VDF display that presents all essential information regarding the currently playing music, complemented by a meticulously designed rotary selector. This selector facilitates volume adjustment as well as various streaming functions, all while conveying a sense of premium quality.
