Antipodes CX - High Performance Music Server

Antipodes CX

The CX delivers stunning sound quality, far exceeding the audio performance of the EX and DX while also providing high processing power to handle demanding server features with ease. The CX can be upgraded to the CX+EX Solution by adding an EX and the combination provides a further very significant audio quality improvement over using the CX alone.

In designing the CX, we have needed to strike a balance between a number of factors. The CX is principally designed to be powerful enough to meet the demands of processor-intensive applications like Roon. But running CPUs hard produces harsh sound. So the CX uses a full desktop 4 Core i5 processor, run at a relatively low clock rate, about half of its full speed capability. If you like analogies then it is like driving a de-tuned, but torquey V8. This is able to yield the best combination of processing power and sound quality. The clock rate is set at a level where sound quality is not impaired by the CPU’s electronic noise, but by using all 4 Cores it can meet demanding processing needs.

In making the trade-off between power and sound quality, we have made sure that the CX can transcode and upsample files to DSD512 using Roon’s DSP features, without any impairment of sound quality. To achieve this, a user needs to set Roon to use ‘parallelisation’, which is Roon's word for using all 4 Cores multithreaded. Because a full desktop i5 has four real threads, and does not use hyperthreading, this produces the smoothest of running conditions to optimise sound quality.

We also want to caution users to be careful about assuming using DSP for upsampling/transcoding will sound better than playing the files at their native resolution. Transcoding on the fly generates more noise interference, DSD loses immediacy compared to PCM, and higher bit-rates can improve high frequency smoothness but reduce presence, particulalry in the lower frequencies. You really should experiment to decide what suits you and your other equipment best. The nice thing with the CX is you have the luxury of doing just that.

If you decide to play your files at their native resolution, the CX is not wasted. The greater processing headroom delivers a refined, rich and full sound that is notable for its speed, scale and ease.

CX Internal With SSD Plate

Because the CX does not have a cooling fan, you should ensure the CX has adequate ventilation if running processor intensive functions, and we recommend you leave the background audio analysis function in Roon at its default settings. If you decide to set CPUs to run at 100% to complete background analysis you should monitor the heat of the CX case.

Owners of a CX can use any USB CD/DVD drive to auto-rip their CDs, or add the new P1 platform, with its integrated high precision ripper. The CX is designed so that you can add your own storage disks, and you can self-install up to 4TB of HDD or up to 8TB of SSD storage. Use of SSDs improves dynamics, high frequency sweetness and speed, and is significantly more musically engaging. If you prefer to have your storage disks pre-installed then your dealer can assist you.

Outputs are USB or Direct Ethernet. Direct Ethernet means the CX has two Ethernet ports. Connect one to the network for setup and remote control purposes. Connect the second Ethernet port direct to an EX or an Ethernet input on a DAC using a short high quality Ethernet cable. The direct link cuts out noise from the rest of the network and benefits from the very low-noise environment of the CX.
