Our take on the brand
Look inside the brand
Our interview with the brand
What are two key technological innovations or strong opinions that differ you from other brands?
What's your approach to customer support?
Musical Fidelity (like other Audio Tuning brands) is structured in a pretty traditional way, whereby support and advice are best administered on a local level. Of course, they have a technical team positioned at HQ to help all their partners around the world, and in some more extreme cases you may need to be put straight through to this team. But it's the job of the distributor to support the territory in the best way it can.
What are your favorite tracks for showcasing the strength of your products?
I can tell you this, as we've done this recently for others. These are personal choices:
Simon Quarry – the chief designer – selected these three.
- Low Desert Punk – Brant Bjork
- Moon Love – Electric Moon
- Psychic Chasm – Ozric Tentacles
Heinz Lichtenegger – the brand owner – selected these two:
- Tosca – Puccini, Leontyne Price, Di Stefano, Taddei / Vienna Philharmonic with Herbert von Karajan (Decca, 1963)
- Don Juan – Richard Strauss, Tod und Verklaerung, Also Sprach Zarathustra / Vienna Philharmonic with Herbert von Karajan (Decca, 1960)
What other products pair best with yours?
This is a tough one! Partly because of the diverse range of products on offer from Musical Fidelity. For example, with the A1, we have a lot of success pairing this amp with Klipsch Heresy or Forte IV – but in smaller rooms, our own-brand LS3/5A are a wonderful choice. For Nu-Vista, we pair very nicely with Piega – which requires some deeper power reserves to really get going. So I would say it's very difficult to pair the sonic ID with one brand in particular. Musical Fidelity pairs pretty nicely with a wide range of products, giving customers a great degree of choice.

Our take on the brand
Our summary
Product Strengths
- Unique features and impressive performance in a compact form factor
- Exceptional build quality
- Larger, responsive, and intuitive touchscreen UI
- Considered by one reviewer to be the best sounding DAC they have heard under $3,000
- Genuinely neutral and lifelike sound signature, without compromising resolving capability
Product Considerations
- Expensive, at $2,800 or 2,800 euros, which is a significant investment
- Limited display viewing angles, due to using a TN panel instead of an IPS, VA, or OLED
- Hypsos power supply is a subtle upgrade, not necessarily worth the extra cost unless already owning other Ferrum products
- Stock power supply is not as good as the Hypsos
Comparisons (according to reviewers)
- Compared to Gustard X18, Wandla lacks the sterile presentation, offering a more genuine neutral sound
- Compared to EverSolo DAC Z8, Wandla is closer to a true neutral sound signature and overall more realistic sounding
- Compared to Holo May KTE, Wandla was happily trading blows on outright soundstage size, and resolution was pretty much on par
- Compared to Chord Dave, Wandla provides similar sound and performance at a more attractive price
- Compared to Rockna Wavedream Signature, Wandla has similar liquidity and refinement but at a fraction of the price
Takeaway: The Wandla is an impressive DAC focused on sound quality, offering a number of unique features and customizability options. It is a great option for those looking for high end sound in a small package.

Our summary
Product Strengths
- Precise, accurate, and musical sound, delivering what the disc or file was created to sound like
- Excellent jitter suppression, getting the most out of digital sources
- Versatile, it can be used as a digital format converter
- Weighty, full-bodied—tape or vinyl-like—sound
Product Considerations
- The stock power supply can be improved with a higher quality 6 to 9 volt supply or the Weiss PSU-102
- High-resolution sampling frequencies via USB of 352.8 and 384 are down sampled to half their value at 176.4 and 192
- May be a bit too harsh, even for some systems
Comparisons (according to reviewers)
- Some reviewers preferred the Weiss DAC204 to the Chord Dave due to impressive detail and holographic 3D imaging, although the Weiss is not as sharp or dynamic
- The DAC204 is considered to be on the same level of sound quality as the Chord Hugo 2 and Chord Cutest
- The DAC204 sounds just like the 501, despite being significantly less expensive and lacking the DSP, preamp, display, and remote control features
- The Weiss DAC204 is more open, dynamic, and punchy, while the Meitner is all about the midrange with beautiful and rich vocals
- The Weiss DAC204 brought more of everything making music sound more present, more physical, and more engaging in comparison to the AudioQuest DragonFly Cobalt DAC
- The main difference noted between the Weiss and the Totaldac d1-unity was one of body and weight
Takeaway: The Weiss DAC204 is a compact and versatile DAC that delivers high-end sound quality. A good fit for those who want a DAC that provides natural, realistic reproduction and accuracy without extra features.
