The latest DAC501 rave review

Mr Steve Huff recently published his review of the DAC501.

The latest DAC501 / DAC502 software release

The version 2.5.1 software allows the DAC50x units to be used more flexibly. It is now possible to designate both XLR/RCA outputs and the frontpanel JACK output as either driving loudspeakers or headphones. Now it is possible to e.g. connect a headphone amplifier to the XLR outputs and have the headphone signal processing active on that output. 

This led to the implementation of four separate banks of Global Presets. Two banks each for XLR/RCA and JACK outputs and then one each for speaker or headphone mode. Also the Snapshots stored are now accessible across all output modes. This makes it much simpler to set up a library of Snapshots and Global Presets.

Celine Dion uses ADC2

"I have been using the Weiss ADC2 for many years to track Vocals.
I love this unit, it's incredibly versatile, the meters and ergonomics are excellent.
I like the fact that I can change the input calibration instantly with the turn of a knob.
The ADC2 captures all the subtle details of the performer and the recording chain,
it's transparent with a high-end Weiss finish to the sound.”


Mr. Francois Lalonde

Vocal producer/ Recording and Mix Engineer for Celine Dion.

Notes on new Mac-OS Catalina and the iPad-OS 13.1.2

The recently released new Apple OS-es have the following consequences with our products:


SARACON: Does not yet work with Catalina, we are working on a 64Bit version of SARACON.


Firewire Driver: Does work with Catalina. Make sure to use the latest driver version as listed on the Downloads page.


MAN301 App on iPadOS 13.1.2: The app crashes when the volume is changed with the fader or when the progress bar is moved or when leaving the large cover art display. The volume can be controlled by tapping on the speaker icons to the left and right of the volume fader. We are working on a solution.

Deadmau5 on the Weiss/Softube DS1-MK3 plug-in

"I've been a long time user of the Weiss DS1-MK3, it's been a must-have tool for my mastering process, and to see Softube nail it so well has me over the moon, from the UI familiarity to its epic dynamics shaping abilities, it's just about perfect."

Upcoming Klangschloss exhibition

On April 14th and 15th the Klangschloss exhibition in Greifensee / Switzerland takes place. 

We will be in room 8 and will demo our Livebox speaker in conjunction with our new D/A Converter (DAC501 / DAC502) and our MAN301 network player. We will stream audio and video content for a great multimedia experience.

The Livebox speaker tries to achieve what a headphone does - a crosstalk cancellation, with an astonishing effect. (Details see the livebox site). So it makes sense to also play a headphone in our room - we will have the Sennheiser HE1 headphone - probably the most expensive headphone currently available.

New this year will be the "KOPF-HÖR-KÜCHE" room where 7 different headphones can be tested. The audio source for all headphones will be the same, our MAN301 network player.

I am looking forward to welcome you in our room!

DAC501 / DAC502 philosophy

With the DAC50x unit we introduce a new paradigm for D/A converters. The trend for high-end HiFi systems goes toward simpler setups. As simple as e.g. a D/A Converter plus a pair of active speakers.

Audio is streamed from a NAS and/or Internet to the D/A Converter and then conveyed to the speaker. A very short and simple signal path.


In addition the audiophile community starts to recognize that a transparent audio chain is not what we would like to have (yes, really!). We would like to have good sound on any speaker in any room.

A bold requirement which often calls for signal processing like room equalization, tone control, loudness control etc. Thus it makes sense to have various signal processing tasks done in the D/A Converter. This is where the DAC50x comes in handy. The DSP chip in the DAC50x takes care of tasks like:

- volume control

- room equalization

- creative equalization (tone control)

- vinyl sound emulation

- crosstalk cancellation for a live-like playback

- de-essing (remove sharp sibilances)

- constant volume keeping

- loudness control


Plus more in the pipeline, downloadable to the DAC50x unit. This makes the DAC50x the ideal unit for current and future audio setups.


jan. 2018


Currently we are evaluating a new method for loudness control. Back in the old days of HiFi, the amplifiers usually had a switch or knob to control the "loudness". This means at low listening levels the low and high audio frequencies have been boosted to compensate for the human ear's level dependent frequency response.

We plan to implement a new approach to solve this problem, but would like to know what users think of our take on it beforehand.

If you would like to participate we invite you to download the tracks from here:



Each track contains short snippets of A/B/A/B etc. versions. For each track write down whether you prefer A (with loudness compensation applied) or B (no loudness compensation) and let me know your findings. The differences are fairly obvious, i.e. not a "golden ears only" test.

Important to the test is to listen at a moderate level, recommended listening level is around 75dB, i.e. where loudness control makes sense. E.g. a level you may use when listening at night.

Fidata streaming app

The IODATA company, manufacturer of the Fidata NAS units, just published their free iOS app which allows to stream files from a NAS (any NAS, not only Fidata) to a renderer unit, like e.g. our DAC501 / DAC502 units or our other D/A Converter units which can be equipped with an Ethernet interface.

Have a look in the app store for fidata music app.


If you got any feedback on the Fidata app let us know, we are in contact with the Fidata people and can suggest enhancements.

Interfaces for our D/A Converters

All our D/A Converters, namely DAC1, DAC2, Minerva, DAC202, Medea, Medus, can be equipped with USB/DSD or Ethernet or Firewire interfaces. Such an upgrade can make sense in these cases:


- Interfacing via Firewire becomes difficult because of the need for adapters for Thunderbolt. Although it is still possible, even with Thunderbolt 3, which requires two adapaters from Apple (TB3 to TB2 to Firewire).


- The wish to be able to play back DSD64 or DSD128 files and PCM files at 352.8 kHz or 384 kHz. This can be done via the USB/DSD interface.


- The wish to stream audio directly from NAS or Internet to the D/A Converter. This is possible via the Ethernet interface under control of apps like fidata or mconnectHD or Creation 5 etc.


Get in contact with us if you would like to upgrade your D/A Converter.

Weiss exhibiting at the High-End HiFi show, Regensdorf, Switzerland

Come and see and hear our new DAC501 / DAC502 D/A Converter in action. We will play live music videos on a large screen and have a crosstalk cancellation (XTC) based speaker system. This will generate a "being there" feeling never experienced before (unless being there, yes).

The XTC is generated via the DSP in the DAC501 unit. Other DSP features are a room equalizer, a creative equalizer and a vinyl simulator. 

Don't miss room 343 at the Movenpick Hotel in Regensdorf. Saturday / Sunday November 4. / 5.

Weiss at the AES Convention in New York

Already history - but a very nice one: We demonstrated our LiveBox Crosstalk Cancellation speaker at the AES Convention. Even the super critical pro audio ears appreciated what they heard. To many the sonic sensation was a big surprise. Something one never hears from a standard stereo setup. The Livebox will be soon released in our Highend HiFi product range. 

At the AES Convention there were many exhibits, workshops and papers dealing with 3D audio, binaural audio, ambisonics etc. A clear sign that the audio industry is moving towards immersive audio. Virtual Reality and Augmented Reality are just around the corner...

DAC501 / DAC502

The DAC501 / DAC502 units are coming - finally


Towards end of next month (April) we will be able to start shipping the long awaited DAC501 and DA502 units.


We have been through a long process of hardware design work and software writing and refinement. In addition the actual manufacturing of the units was delayed due to various circumstances.


I am very grateful to all our customers who showed great patience. You will not be disappointed - the DAC501 / DAC502 is probably one of the most advanced D/A Converters currently on the market. The digital signal processor in the unit allows for audio treatments which give "highend audio playback" a new meaning.


Thank you - yours sincerely

Daniel Weiss

Audio Over Ethernet

I am happy to announce another interface for upgrading our D/A Converter models: An audio over Ethernet card which supports all standard rates up to 192kHz and all the popular audio file formats.

This interface makes your D/A Converter an UPnP / DLNA Renderer unit, which is connected to your LAN via an Ethernet cable. A typical use case looks like this:

- To your network you have connected a NAS (Network Attached Storage) or a computer with audio files shared on the network.
- On the same network there is the D/A Converter with the Ethernet interface.
- An application on your phone or tablet controls the playback of files to the D/A Converter.

The nice thing of such a setup is that it can be controlled from any device and the audio files can reside on any other (or the same) device.
It is also possible to stream the files on the phone or tablet directly to the D/A Converter. This makes it simple to share the D/A Converter amongst several users with their individual playback devices.

The technical details of the Ethernet interface:
- UPnP AV 2.0 / DLNA
- plays and decodes common audio formats from HTTP streams
- resolution up to 32-bit, sampling rate up to 192kHz (DSD in preparation)
- support for gapless playback
- bit-perfect data transmission
- 2-channel asynchronous endpoint with external clocking for jitter-free playback
- Supports these formats: WAV, AIFF, FLAC, ALAC, MP3, AAC

The Ethernet interface can be built into the Weiss D/A Converters, namely:
DAC202, Medea, Medus, DAC1, DAC2, Minerva.

Streaming from the Internet with the MAN301

Occasionally I get inquiries from MAN301 users about how to play those streaming websites (like Tidal, Spotify, QoBuz etc.) via the MAN301.

This can be easily done via the Airplay feature of the MAN301. With the icon in the lower right corner on the iPad the menu for selecting the Airplay mode is shown.
After selecting the Airplay mode, tell the iPad to play audio to the MAN301. This is done by swiping from the lower edge of the iPad upwards, which opens a menu where the MAN301 device can be selected for Airplay.

Now open the application of the streaming service you like to play and start playing tracks. The tracks now play via the MAN301. The volume can be controlled via the buttons at the iPad.

The Airplay streams in 44.1 kHz /16 Bit format, which is perfect for the streaming sites. The user interfaces of the various streaming sites are maintained with this scheme, which is a very nice feature, considered that the streaming sites keep updating their user interfaces. In addition all streaming sites are supported automatically.

In that manner all audio played on the iPad can be redirected to the MAN301. E.g. you can also play from Youtube or from your local music collection on the iPad.
Of course all Airplay capable devices can use the MAN301 for playback in that manner.
