[HIVI new product thorough test] Network audio player "Rumin X1" is an emotional drawing the excitement of music, a multifunctional and high -quality sound, and the excitement of music.

In the January 2019 issue of HIVI, we thoroughly checked the sound quality of Rumin X1, operability/response, and the ability to respond to the source.The result is as in the magazine.The writer who owned the S1, which was the previous flagship, was able to confirm the overwhelming improved sound quality.

At the time of the interview, there was an interesting discovery, which is a significant sound quality improvement effect when trying out the optical Ethernet LAN connection (hereinafter referred to as the optical LAN connection) using an optical fiber cable.The X1 is equipped with a port compatible with SFP (SMALL FORM-FACTOR PLUGGABLE) compatible with the connection method, and in the same way, it is generally combined with SOTM (Som) network hub and SNH-10G.The difference between the LAN connection using the RJ45 terminal, the sound quality improvement effect was confirmed.

The sound of the entire tune from the server to the X1 is overwhelming!

First, connect the SOTM external clock, the hub SNH-10G supplying the clock from SCLK-OCX10, and the Fidata server HFAS1S10 and Rumin X1 are connected with a regular LAN cable to hear the sound.In other words, it is a standard network configuration we usually use.

DSD11.The 2m㎐ sound source "Stravinsky: Petrushka/Ancelme Conducted Swiss Romand Orchestra" (hereinafter "Petrushka") has a dynamic string instrument and all bands.The 96kHz/24 -bit/FLAC "Solid State Survivor/YMO" (hereinafter referred to as "YMO") has a good sound of the synthesizer, and expresses the air as if linked to the late 70s.Loseless music streaming service, TIDAL (Tidal, not in Japan), "Attention/Charlie Puth" (hereinafter "C Puth") is a realistic position between left and right speakers, and has a lot of information.I was able to reconfirm the wonderful basic sound quality of Rumin X1.

Next, as before, connect the hub and the player with an optical LAN.Specifically, a dedicated LC connector with an optical fiber cable was connected to a network player and an SFP port for each hub.By the way, optical LAN connection has two major standards, single mode and multi -mode, and the diameter of the transmission protocol (communication procedure) and optical fiber is different.First of all, when listening to these two methods, the single mode was excellent in hearing SN ratio and resolution.So all the impressions at the time of the light LAN connection are all in single mode.

In the optical LAN connection method that is often used for business use, it is operated in various standards due to differences in transmission distance and signal bandwidth while using SFP terminals.Regarding the structure and transmission method of the cable, there are also "Single mode (above)" and "multi -mode (lower photo)".This time, when I tried the quality of both modes with the conditions, I was impressed during the single mode.HIVI's thorough interview article in the January 2019 issue is also a test in single mode, and this time it is also based on single mode.

"Petrushka" has a lower noise level compared to the LAN cable connection, and the space outlook is better.I would also like to mention that the sound clarity is high in Pianissimo."YMO" has a significant sound quality improvement effect as if the frequency range spreads and the freshness of the master tape has increased.Physically, the noise that flows between devices through LAN cables and RFI (radio frequency interfere)/EMI (electromagnetic wave obstruction) noise, etc., which are considered as an antenna as an antenna.It was clearly felt as a sound quality.

Next, using the MC220 of the TP LINK media converter that converts optical LAN connection to a general LAN connection, I tried to connect the optical LAN between S10 (server) and SNH-10G (hub).However, using this media converter can not only merit but also a disadvantage of conversion processing of "electric/light".

However, in "Petrushka", the noise floor was further reduced, the absolute amount of information increased, the intonation expression was more rich, and the appeal of songs and performances -it may be said that it may be called music and musicality.。In "YMO", the rise of the synthesizer becomes even sharper, and "C Puth" changes naturally and dynamically.I don't want to write too much, but the effect of connecting all voice lines from the server to the player is enormous.Once you listen, you can't return to it.

How is your transportation skills?Try the cooperation with the latest DAC

The excitement of the light LAN connection is not cooled, but then the use of the X1 USB digital output is performed as a transport.Select a USB digital output in the dedicated application "Rumin App" and connect the X1 and D/A converter with a USB cable.The LAN is connected to the light LAN via the same as before.

I also tried using the development form that uses Rumin X1 as a network transport using USB output.This is a method of making use of your favorite D/A converter without dare to use X1 analog audio output.In addition, the correspondence of file playback changes due to the X1 and DAC side, and in these three models, D-2 and DAVE DSD11..The 2MHz sound source was played, but the DP-750 DSD5.It was played up to 6MHz sound source

First, from Soul Note D2."Petrushka" has a sound stage spread and dynamically depicts."YMO" sounds an exquisite groove with a density and excellent tone.It has a sound that attracts guigui and listeners, and has the impression of D2 in addition to the high basic performance of X1.

Next is Dave of British code, known for its high -end audio fans."Petrushka" is a harmony of the harmony, and the exquisite and rich musicality that does not fall into the amount of information is attractive.The synth base of "C Puth" is a dynamic expression that takes a rhythm with the whole body, even though it is heavy.This is really wonderful.It is an impression that X1 is firmly drawing out the personality of the D/A converter.

Finally, I tried using the DAC function of the DP750, the SACD player of Accuphase.Is it a problem with compatibility, DSD11 in this combination?.I couldn't play 2m㎐, so DSD5.The 6m㎐ played "The Very Thout of You/Emily Claire Barlow".In this song, the smooth texture of DSD is attractive.In this combination, I felt a sound full of centripetal force, which draws listeners strongly.

Not only as a player but also as a transportation

How did you check the performance of Rumin X1 twice over time?The X1 has a thorough sound quality countermeasures, such as the state -of -the -art DAC chip, Femtocrock system with FPGA (programmable gate array elements), and new power supply parts that are strongly isolated by digital and analog parts.In addition, PCM is up to 768kHz/32 bits, DSD is 22.Supports to 5MHz.The specifications of X1, such as built -in MQA's full decoder, are almost perfect.Moreover, not only is it excellent in specifications, but the sound is so good that the tongue is wrapped.Four years from S1 released in 2014."Most of the X1 development period spent money to improve sound quality," but it is not Date.

Let's conclude.As for the X1, as a single network player, it can be said that the emotional sound is the biggest attraction.And if you use it as a transport, you can increase the basic performance of the D/A converter without spoiling it.I think this is the most important performance for transport, though there are many ways of thinking.Regardless of either use, the introduction of optical LAN connection is a major advantage of X1.

From the end of last year to this year, Rumin has been actively developing products, including the announcement of the middle -class network players T2 and the U1 mini for small network transports.Keep an eye on Rumin's future development.
