1st of all .. a youtube listening test is IMHO no valid test.
AFAIK the audio files become modified and can't be regarded as lossless anymore.
I do not know what exactly they do .. but I would at least be careful taking these sound samples as a reference.
> Please tell me why i should buy RME dac over others
Well, my perspective as satisfied RME customer since 6+ years:
I could tinker with you in technical terms, but I don't. You are welcome to read the manual of the ADI-2 DAC or Pro, the first few pages will give you a good overview of what the units can do.
I'm happy to recommend RME to others, because I feel that I'm in good hands with this company as a customer. Why ? RME has earned its spurs in the studio business and can rightly be considered one of the most innovative challengers in the market. There is no other manufacturer that offers such a good package of reliable hardware, drivers, features and software.
The products are designed with great attention to detail and are maintained afterwards for a long time. Additional ideas / demands from customers have been implemented by firmware updates across the last years and it also led to product refreshes for stuff that could not be anticipated years ago.
Some RME devices have been supplied with current Windows and Apple drivers for nearly almost 20 years now.
RME is also not a company that wants to talk the customer into buying a product with questionable ("HiFi voodoo") features. They are also very open in communicating technical data, which can be achieved by their products and be validated by everyone. As HiFi Customer you also benefit from the know-how that this company gained in the studio area.
That's why RME devices enjoy a good reputation and even have very good resale prices.
In my opinion the most important features of the ADI-2 * product-line are:
- RME gets surely everything out of the DAC chip (simply good overall design)
- High Audio quality to drive my Gaithein Monitors, Audeze LCD-3 and Accuphase Class A HiFi
- For the communication with the PC no 3rd party communication chips are used, all being done by RME in the FPGA
- FPGA based design, everything can be fixed / flashed
- RME's SteadyClock feature eliminates the outer influences of clock jitter, refreshes the clock signal and performs the D/A conversion with the internal Femto Second Clock in high quality. This eliminates any clock jitter, be it from USB or SPDIF/ADAT.
- Support for different reference levels (4) and the auto reflevel feature. DAC: the four reference levels adjusted more to HiFi devices usual demands
- 5-band PEQ to correct / adjust certain "faults" of your phones
- Great features, e.g. Slow Volume Ramp-up when plugging in/out the Phones, Dynamic Loudness, Remap Key Feature, the super status overview with which problems with digital connections can be easily troubleshooted, real manuals in very good quality and even the printed manuals you get in two languages, ..
The best introduction into "RME" as company you can find here in this interview, it tells you a lot about the spirt of this company: https://www.rme-audio.de/interview-matt … stens.html
Finally the over 19.000 postings of Mr Carstens alone on user forum speak a clear language, that RME is very customer oriented. Only this way good ideas/demands from customer can flow back into product maintenance and development.
In terms of sustainability after purchase, what you are looking for, RME products give you a very high value.
