upcoming Meridian Sooloos updates:

Format Roadmap
• Changes are under way to enable core support for 24-bit ALAC, DSD, and ‘8x’ sample-rates including DXD via MQA. As currently, the core mediates all formats to the various endpoints and no-one will be left behind.
• We are adding support for albums and sets with mixed-sample-rates.
• MQA. The current system is MQA-aware but during the next few months MQA decoding will be added.
• As currently, the Sooloos system is able to send the optimum signal to each end-point.

Hardware Roadmap
Our recently announced 818v3 and 808v6 fully support the formats listed above, including native decode of DSD (DoP) and MQA and, as you might expect, there are a number of other announcements coming.

Exclusive content
Curated collections via TIDAL. One of the biggest problems for newcomers to serious music listening is building a collection that suits their taste. In the past this involved ripping CDs or laboriously accumulating downloads. With our special integration of TIDAL we can add simple-to-install curated music sets as a small download.

Core and Storage Hardware
Last year we released a plug-in for the QNAP NAS range that provides Sooloos-compatible storage. Beginning with the next release we add an option to run our Sooloos Core on QNAP. This means that more music lovers can join the Meridian Sooloos world without any compromise to sound quality. A QNAP, an iPad and a Meridian Sooloos end-point will get you started!

Control
You may have noticed rapid developments in the iPhone and iPad clients. The iPad app is undergoing further optimisation and, as usual, when that is released it’s a free upgrade.

DSD is a big turn around for Meridian. We'll see how Roon Labs (The software team behind Sooloos ) helps Meridian endpoints.

So from the looks of it, MQA is going to be a Tidal and Meridian collaboration, I guess?

Yes, they are partnering for TIDALs hires service in MQA.

I really like the inclusion of DXD as that is probably the best demo I've had in a long time of true hires. (Was with the Original Horus ADC/DAC and MBL 101 speakers). Filters are often bad..

By nature they are lossy.

Do you have a knowledgebase link to some of Meridian's white papers on Filters and Digital audio? I recall there is some extensive research here done by the team at Meridian.

Indeed, here it is:

P14-3 The Audibility of Typical Digital Audio Filters in a High-Fidelity Playback System—Helen M. Jackson, Meridian Audio Ltd. - Huntingdon, UK; Michael D. Capp, Meridian Audio Ltd. - Huntingdon, UK; J. Robert Stuart, Meridian Audio Ltd. - Huntingdon, UK
This paper describes listening tests investigating the audibility of various filters applied in high-resolution wideband digital playback systems. Discrimination between filtered and unfiltered signals was compared directly in the same subjects using a double-blind psychophysical test. Filter responses tested were representative of anti-alias filters used in A/D (analog-to-digital) converters or mastering processes. Further tests probed the audibility of 16-bit quantization with or without a rectangular dither. Results suggest that listeners are sensitive to the small signal alterations introduced by these filters and quantization. Two main conclusions are offered: first, there exist audible signals that cannot be encoded transparently by a standard CD; and second, an audio chain used for such experiments must be capable of high-fidelity reproduction.

Awesome! You rock! :rockon:

This is exactly what I was looking for!

I just received a call informing me that the date for Spire Integrated's MQA demo event has been set for the 21st of this month. I have already confirmed my attendance and am looking forward to the opportunity to hear this for myself.

New release under "Messages" tab fixing Tidal issues. :)

4 months and counting....what is going on with Meridian????
