The MPT-8 Dream Transport was initially delivered as part of a combo for the MPD-8 Dream DAC review. During that review, I found that the MPT-8 offered such extensive functionality and achieved such excellent results that it warranted a dedicated review. In this review, I will assess all of the MPT-8’s functionality using three different servers and multiple DACs, including the MPD-8.
MPT-8 Description
The MPT-8 is designed to be a one-stop source solution. It contains a CD / SACD Transport based on a high-quality mechanism developed by D&M specifically for audiophile applications. The MPT-8 can output native mode DSD via the fiber optical PLINK connection.
The MPT-8 is also designed as an ideal platform for the Stream-X2 option, making it a Universal Transport. In addition, it provides extensive connectivity for many external sources.
As standard, the MPT-8 can interface with a wide range of digital sources via Coaxial and Optical Toslink S/PDIF, AES/EBU, USB, and PLINK. The optional Stream-X2 option is connected via RJ45 and also offers a USB input to connect USB flash disks or HDD/SSD storage devices. The output signal is available via AES/EBU and PLINK.
The Stream-X2 option enables a wide range of Playback Designs components to include very high-quality streaming over an RJ45 network connection for local library- and cloud services, such as Tidal, Qobuz, Deezer, vTuner, NAS, and Roon. Any DLNA/UPnP-compatible app will work with the Stream-X2 option, but the best ones are JPLAY for iPad and Bubble UPnP for Android.
The MPT-8 is powered by the same high-quality linear power supply used in the MPD-8 DAC and incorporates extensive buffering, re-clocking, filtering, and cleaning of all digital sources to prevent any inter-modulation effects from reaching the DAC. As the last step, the digital data is encoded in its native format and output via AES/EBU or PLINK to be decoded to analog by the DAC.
More about PLINK
PLINK is a variation on ST glass optical, specially adapted by Playback Designs to carry the delicate music signal from component to component whilst supporting all sample rates for PCM and DSD natively. PLINK is an optical format but uses an entirely different interface than Toslink. Instead of relying on an LED source, PLINK uses a high-quality, low-jitter, Laser ST fiber optic interface. This interface is normally used for very high bandwidth communication links where receivers require an extremely low-jitter signal for reliable decoding. The music signal travels over PLINK using a much lower bandwidth protocol than the specified limit of the media, further increasing robustness against jitter and allowing for extremely long cable lengths (up to 300m). Cables for PLINK are specified for multimode, 62.5/125µm.
The first version of the PLINK interface was launched more than 15 years ago and supported DSD up to 5.6MHz. This version is called “Classic” and is implemented in the Playback Designs 5-series products and IPS-3 (unless they have been upgraded). As technology never sits still, the DSD sample rate has been expanded to 11.2MHz several years ago. Accordingly, Playback Designs also expanded the PLINK format and called it “Sonoma” reminiscent of its Sonoma workstation origin.
It’s worth noting that PLINK is compatible with NAGRA LINK, meaning that the MPS-X Network Transport is compatible with NAGRA DACs with a NAGRA Link input. And the same logic applies to the MPT-8 Transport. This is worth noting as there are currently no CD/SACD Transports in the NAGRA catalog.
Review Context
The MPT-8 Dream Transport is a natural partner for the MPD-8 Dream DAC, which was reviewed separately. I will be using the MPD-8 again in this review, but will focus on the MPT-8, and will use it with other DACs as well.
The MPT-8 was listened to in the main system that consists of the CH Precision C1.2 DAC, CH Precision L1 preamplifier, CH Precision A1.5 power amp, and Magico S1 MkII speakers. Digital sources include the Antipodes K50, Grimm MU1 and Taiko Audio Extreme music servers, the Aqua Diva M2 CD transport, and the Aqua LinQ network interface.
All interlinks are Driade Flow Link Reference 808, balanced and unbalanced, and the speaker cables are Driade Flow Reference 808.
For support, I use Artesania Exoteryc racks and Aire floor platforms with Carbon Fiber Linear Arms, and HRS EXR Stands and Floor Platforms.
Setting the Stage
When first reviewing the MPT-8 as part of the MPD-8 Dream DAC review, I discovered that all my available sources worked exceptionally well when connected directly to this excellent DAC. All three servers’ characteristics were fully retained and presented with fantastic purity and clarity, while the DAC always got to the musical core of the performance. In summary, the MPD-8 performed so exceptionally well that it earned a Magnificent Masterpiece award.

Hi Christiaan,
thank you, great review as usual.
One question:
Only considering streaming from Qobuz, after this review which set-up (upstream to the DAC) provides the best performance when using MPD-8 as DAC?
Thank you
Matt
You mean which server? I will leave that to the reader to decide as they all have their unique characters, which I described in the MPD-8 review. The beauty of Qobuz is that you can also stream directly, without a server, directly from an app. This also sounds really good.
Hi Christiaan, I appreciate your review. I had a MPS-8 + Stream X2 and used it for some months with MPD-8, connected by P-Link. The sound was really impressive, better to all my previous digital set up. Listening to CD or SACD proved that PLAYBACK DESIGNS has realized a fantastic player at quite an expensive price but not stratospheric. Then I use TAIKO Extreme + MPD-8 with USB and the sound from Qobuz or server is much more open, more realistic in soundstage and dynamics increased to an unpredicted level of realness. I much recommend to use MPT-8 or MPS-8 with better feet than the original that use felt. Remove the 3 felts, use top rank cones + base and the sound will improve greatly.
