The DAC 501 mk2 combines conversion with audio processing, network playback, preamplifier functionality, and headphone listening. The Helios is presented as the flagship option on this page, for listeners considering a high-end digital front end.
Before choosing, consider your current source components, whether you need volume control or headphone output, the digital connections your system requires, and whether you want built-in network playback. These details help determine which Weiss component makes sense for your listening setup.
Important: Confirm the exact DAC 204 model and its current features before publishing a detailed comparison. Weiss’s current product catalogue identifies the model as DAC204-MK2, while the page lists “DAC 204.” The manufacturer describes the DAC 501/502 MK2 as DACs, audio processors, and network renderers.
A Weiss DAC can serve as the central digital component in a carefully matched stereo system. Depending on the model and configuration, it may connect to a computer, digital transport, or network source, then send an analog signal to a preamplifier or power amplifier. The DAC 501 mk2 also includes preamplifier and headphone functionality, which can simplify some system configurations.
For the best system match, consider the available digital inputs, analog outputs, amplification, and how you plan to control playback. Explore our digital streaming components to see how Weiss fits within our wider selection of digital audio equipment.

I first went to In Living Stereo in 2010 or so with a modest budget and walked away with a used Rega P5, new cartridge and a phone stage. Later I got Prima Luna integrated amp then Dynaudio Focus 350 floor standing speakers. Eventually, as time has gone by, I upgraded to a Leben 600x, Leben phonostage and Devore Super Nines. As I built up my system bit by bit, Steve Mishoe and Steve Cohen have guided me to a place where I am truly satisfied. I can't thank them enough! They have great taste and can work with any budget. I trust them implicitly and am thankful that a place like this is here in New York City. Highly recommended!Posted on Google![]()

I have been a faithful customer of In Living Stereo for over the last ten years and believe it is a must-visit even if you are not a hardcore audiophile. First, hands down, the store has the best audio equipment in terms of sound realism, price, durability, and aesthetics. (Note that they don't carry video equipment.) Second, the store is owned and operated personally by Steve M., whose knowledge and attention to detail are unmatched. Steve gives you personal attention, helping you select the best equipment in your price range that meshes and achieves the best collective sound possible. Importantly, Steve doesn't skimp on the details and matches, for example, speaker wires, interconnects, and sound conditioners to complement cartridges to turn tables. Finally, Steve is an extremely nice and honest individual, singularly focused on making sure you're happy with your purchases for years to come. As an added bonus, he listens to all types of music -- and is happy to audition the equipment with any music you bring.Posted on Google![]()

My old amplifier shorted out and stopped working. Every amplifier I had since I was a kid was either a worn hand-me-down, or thrift store finds. I finally have enough money to invest in something nicer. I stoped by In Living Stereo, and Steve showed me a bunch of different options for an amplifier. He was was super helpful with all my questions. I've never had a good Amplifier despite collecting records for over 20 years. I looked at getting a refurbished vintage amp, but found that most prices were the same as a new one. With Steve's help, I picked up the Rega Brio, and my records have never sounded so good. Even music streaming sounds so much better. I highly recommend stopping by and talking stereo equipment. You never know just how good your collection can sound.Posted on Google![]()

I walked into In Living Stereo as a beginner audiophile and was greeted by Steve who walked me through various speaker brands and educated me on buying high quality speakers. The store is amazing, a well curated selection and really cool listening rooms. He let me listen to a bunch of the high end speakers on the floor. He ended up giving me a great deal on a floor version of Dynaudio speakers, which are my first pair of high fidelity speakers. Steve was super helpful and FaceTimed me to help me set up the speakers at home. Highly recommend!Posted on Google![]()

I purchased two great sounding systems - and learned a ton about hi-fi - from Steve over the years. It is a joy to listen to records on world class equipment at the In Living Stereo showroom.Posted on Google![]()

I was looking for a turntable and a pair of speakers. Steve set up a couple of systems for me to listen to and I was able to compare them (Spendor and Devore speakers). He was knowledgeable and patient. I also a got chance to listen to the G.I.P. horn speakers. It was like the musicians were in the room with me, they were truly amazing. Too bad G.I.P. is way outside of my price range. I had a great experience.Posted on Google![]()

Steve was very helpful in teaching me about stereos and what to look for in audio equipment. I didn't have a huge budget but it sounded great, even better than I expected! He showed me the Rega Planar 3 turntable and the Dynaudio bookshelf speakers.
Weiss Engineering systems combine professional audio technology with high-end home listening performance. The following questions address key considerations when integrating Weiss components into a modern digital streaming system.
Weiss Engineering products are based on professional mastering technology, focusing on accuracy and precision rather than coloration. Their studio heritage and advanced DSP capabilities set them apart from many traditional hi-fi brands.
Some Weiss DACs, such as the DAC501 and DAC502, include built-in network streaming capabilities. These components can function as both a DAC and a streamer, simplifying system design while maintaining high performance.
Yes. Weiss components are widely used in reference-level systems due to their transparency, detail, and flexibility. Their ability to fine-tune sound through DSP also makes them ideal for optimizing complex setups.
A DAC converts digital audio into an analog signal for an audio system. A network renderer receives digital music over a network and sends it to a playback component. Some Weiss models combine these functions, reducing the number of separate components needed.
Some Weiss models include preamplifier functionality, allowing them to control output level in compatible setups. Check the specific model’s outputs and system requirements before connecting it directly to a power amplifier.
The DAC 501 mk2 is the more compact model. Weiss states that the DAC 502 mk2 has a larger enclosure and an additional rear 4-pin headphone socket; the two models otherwise share the listed core functionality.
The DAC 501/502 MK2 includes adjustable digital signal processing features, including room EQ. The available processing and setup options depend on the model and configuration.
The advanced DSP and clocking features of Weiss Engineering DACs require expert consultation to maximize their performance.
