Welcome dCS Varèse

Thank you for posting Andre.

I found these two parts of the review noteworthy/interesting:

"The third chassis is the Core, which dCS calls “the heart” of the Varèse music system. The largest component in the system, the Core handles several operations including audio input, conversion, oversampling, noise shaping, filtering, and streaming. Indeed, the Core handles most of the Varèse music system’s processing and “heavy lifting,” relieving the Mono DACs and their power supplies from multiple noise-inducing, power-draining processes. It includes an integrated network streamer that, together with the new dCS Mosaic ACTUS app, enables PCM rates up to 24/384 and DSD up to DSD512 (footnote 5), and automatically oversamples PCM to either DXD (24/352.8 or 384), DSD, DSD128, DSD256, or DSD512."

And:

"Tomix clock technology arose out of the need to ensure that the Mono DACs were perfectly synchronized so that left and right digital samples were converted at the exact same time, with no delay between channels. With all audio signals passing through and processed in the Core, the Core needed to place time stamps on each audio sample. dCS’s solution—Tomix—embeds a time stamp into the clock signal.

“Tomix is quite a nifty way of precisely sending time signals and unscrambling them without negatively impacting timing,” Cook explained. Transmitted via Varèse’s proprietary ACTUS cabling, dCS claims it superior to the Differential Manchester encoding used in traditional AES3 and dCS-developed dual AES. In Differential Manchester encoding, zeros are assigned a longer pulse and ones are assigned a shorter pulse. The problem with this encoding scheme, according to Cook, is that cable capacitance can affect pulse length, thereby creating jitter. Tomix was designed to transcend such limitations."

This latter point, the further elimination of jitter, must be one of the reasons why the Varèse sounds so incredibly natural.

Having just come back from the Benelux debut of Varese at Alpha High End Audio in Brasschaat, Belgium, I just wanted to do a short write-up of my experience. Now I haven’t been to a hifi show or dealer demo in ages, my only comparison is my own system and some fellow enthusiasts systems so ymmv.

First, hats of to @AndrewS and @Alasdair, for putting on a great show and breathing lots of enthusiasm into their talks. These are long hours they put in. And heavy lifting too :slight_smile:

There were three rooms set up for the occasion (all cabling Shunyata):
dCS Lina + clock, Pass INT-250, Wilson Audio Sabrina X (Andrew)
dCS Rossini Apex player, Pass Labs XP-22, XA60.8, Wilson The Watt + Puppy and Submerge sub

dCS Varese, Pass Labs XA160.8, Wilson Audio Alexia V (Alasdair)

Tbh I don’t have any previous experience with Wilson Audio speakers. I do know Pass amplifiers. The Lina room was enjoyable, had a nice wide and deep soundstage. One thing that was clear is that real low bass extension was missing from the Sabrina’s if you’re used to hearing it in your own system. Andrew also demonstrated the master clock on and off difference which was very good for getting an idea of what to expect from it.
To my ears the Rossini room was actually the most balanced sounding with the new Watt Puppy including the Submerge sub. It was a place to just keep listening without fatigue. It definitely hit a sweet spot.
For the Varese, one word came up for me in this system which is clarity. It was clear that it was throwing new light on any recording, illuminating the recording and making it shine more than before. That to me was the takeway of Varese, I got to hear how it was special and going further than Vivaldi. The rest of the system was very impressive, and Alasdair gave it a workout with an eclectic mix of music. Overall the system balance in that room could have still been better I think.

It was great to be able to hear some really high-end stuff today. Great to hear about the systems, music and stories by Andrew and Alisdair. And nice to visit Alpha, who were very friendly and hospitable.

Alexia V?!
These look like the latest Watt Puppy to me…

Edit: my bad, missed the comment above the picture :wink:

My understanding is they have sold a lot of these and better than expected. I guess the appetite for mass money stacks is there, despite the doubt.

If you build it, they will buy :slight_smile:

I think it’s a stunning rig and would love one but my budget is not in that range :slight_smile:

The engineering team was also recognized with an Innovator of the Year award, which is fabulous.

Well deserved.

Just published: Inside Varèse part 3: The Core:

It is paired with a StreamUnlimited Stream1955 in the Varèse User Interface

The Stream1955 Carrier Board is not used in the Varèse though - thats only used for development work when working with the Stream1955 module.

It is correct that it is not physically part of Varèse, but it was used, and can be used in the future, for developing its streaming functionality. If you read the above linked article, it shows that the 1955 platform has many possibilities for the future, that might end up in Varèse or other dCS product lines, like up to 24 channels of immersive audio, voice assistants, Dolby Atmos, DTS, and with an extra HDMI module in the Core enabling enhanced audio and video signal control, making the combined setup ideal for home theater applications.

Yes I’m familiar with it. In fact, pretty much all the Compute Modules from the various vendors have Carrier Boards that provide IO for the modules for development work, Including Raspberry Pi CMs, Nvidia Jetson CMs, and even the i.MX 8 SOM CM used in the Varèse has its own carrier board for development work.

The Stream1955 has about the same processor as the 2 in the Varèse Core:

NXP i.MX8M Mini/Nano Quad Core ARM Cortex-A53

The difference though is that the StreamUnlimited board (and SDK) is used mainly for Media streaming duties, whereas the i.MX 8 (and SDK) specialises in network communications; in the case of Varèse, between components, i.e it’s what the ACTUS interface is based on.

For example, the empty “DIMM” interface slot that you see in pictures of the Varèse’s Mono DAC board, is where the i.MX 8 Compute Modules goes (visually obscured under the brass heat-sink).

Indeed, the Core houses 2 i.MX 8’s, one for ACTUS, one for streaming:

The Core has the largest amount of processing power of any dCS product to date, with two i.MX 8 System on Modules (SoM) as well as an Artix 7 FPGA. The Artix 7 handles the main functions of the Core. The two i.MX 8 SoMs carry out different functions: one runs the ACTUS interface, allowing ACTUS signals to be encoded and decoded, with the relevant information, audio and clocking signals then sent to the FPGA for processing. The other forms one half of the streamer inside Varèse. It is paired with a StreamUnlimited Stream1955 in the Varèse User Interface, and the two operate in tandem, communicating via ACTUS to support streaming via Ethernet from various services. This enhanced processing power provides ample scope to support any future streaming developments that might occur.

So the Varèse system has a total of 6 (or 7 with Transport) i.MX 8’s!
