Back to the basics!
The Dethonray PRELUDE DTR1+ deliberately dispenses with everything that, according to Anson, chief developer and mastermind at Dethonray, could have a negative impact on the sound: no Android, no streaming, no touchscreen. The DTR1+ is pure sound and
does not have to hide from even the best and most expensive competing products!
Reviews
"When it's time to just listen to your archive alone, there's not a better option for that sole purpose. There's nothing else better for this price tag in terms of pure sound performance... Looking at the DAP market, I doubt anyone can show me a player for this price with a better sound. The DTR1+ certainly has a spot in our Best Portable Player Recommendations." - Berkhan - Headfonia
Dethonray DTR1+ Review - Headfonia Reviews
Energy - but right
Power supply plays a big role in HIFI and portable audio systems. Most portable designs suffer from universal power supply designs that severely degrade signal processing quality.
The DTR1 adopts a dual, high-fidelity designed battery powered power supply system that ensures the separation of digital and analog power supplies to eliminate circuit noise from the source, similar to an enhanced DAP+ amplifier system but with a minimal path and brazed connections without compromise.
The ±8.4V power supply greatly improves the efficiency of the system's clean power delivery, with noticeable qualities of transparency and noise reduction, without over-attenuating the output must.

DAC
DTR1+ chooses the AK4490EQ for its reliability and specific sound performance. The chipset supports up to 32Bit/768K and switchable digital filters, offering different listening experiences.
AKM has strived to reproduce the original sound since its first Delta-Sigma D/A Converter (DAC) in 1989. This becomes the "Velvet Sound" philosophy, which aims to create an active space in sound reproduction, like in a live performance.
Software
A Super Highway for Signals" - The DTR1 runs on a deeply customized Linux OS audio subsystem utilizing an OSS subsystem that is 30% more efficient than the ALSA audio subsystem. The customized and optimized "Nature" decoding engine effectively synergizes with the Linux OS, decodes under optimal conditions and reduces transmission delay.
Patented ultra-light GUI system "Ocelot", custom GAI (Graphics Abstract Layer), GDI (Graphic Device Interface), IAL (Input Abstract Layer), SCM (System Control Module), indexing system for audio files - promises minimal MMI, High speed navigation and supports indexing up to 160000 songs!
Improved software
Redesign of gain and volume audio subsystem:
- Updated gain control to support different IEMs, Earbuds, Headphones.
- Improved volume control to make the sound more accurate and natural.
- Add artist indexing and classification feature.
- Added L/R channel loudness compensation.
Improved hardware
- The low-pass filter circuit has been revised and the DPPU (Desktop Plus Power Unit) has been pushed to its limits.
- Higher resolution and better control options.
- More balanced and consistent sound quality.
