The 4.6 verdict

Posted by: Jack From Adelaide on 14 April 2018

Well, it is now a week since I updated my NDX to use the new 4.6 firmware. My principle purpose was to try and improve the stuttering I had on TIDAL and I didn't expect anything else. The playback through TIDAL is vastly improved. There, post done. WAIT there's more.

What I didn't expect from the description was any noticeable change in sound quality. I don't have a multi-room system (would that I could afford such a luxury!) but I do have quite a good main music system, which includes an NDX.

What I found after the first few albums was that the bass was tighter and more "tuneful". Then I noticed higher resolution. This became apparent almost immediately because my music room is next door to my Mother In Law's bedroom and I usually have to either use headphones or listen at painfully low levels so as not to disturb her. I was reading a book and kept having my attention drawn to whatever I was playing. The instruments and the singers were literally leaping out of the speakers into the room. It was uncanny. At this very moment I am listening to K. D Lang's "Hymns of the 49th Parallel" on UpNP server (minim server - rendered to WAV) and the piano in Hallelujah has this wonderful dynamic presentation, the loud and quiet passages are rendered more noticeably. K.D.'s voice and her exquisite control of the pacing and phrasing is there to hear. In a way that I have never noticed before. A couple of days ago it was Imogen Heap and her Ellipse album on TIDAL. Again the sense of her being in the room was remarkable. At some points it made the hair on my arms stand up. I have listened to E. Power Biggs playing Handel, the bizarre and ultimately rewarding Kaitlyn Aurelia Smith's "The Kid", Dami Im's new album "I Hear a Song" and Ryan Teagues "Block Boundaries". Every album is surrendering new details and expression that I have never heard before.

For those of you as ancient as me it is equivalent to the first time I put a moving coil cartridge on my turntable: I am rushing to listen to old favourites and new music to see what it sounds like now! In some cases I am discovering that they aren't as well recorded as I thought (Scartaglen's "This Nights Fun" was  closed in and you could hear each microphone feed was in a separate acoustic) others are better than I ever suspected.

This upgrade was extremely painful to load (see my recent posts on the issue) but it was well worth the effort. Here is the magic of digital audio: a simple firmware upgrade is like a multi-thousand dollar improvement in your system.

My advice: If you can't load the firmware after an hour of effort, simply take your gear to your dealer and offer them $20 or something to do it for you. It is well worth the effort.

Software (firmware) has the habit to install completely or not at all. I find it very unlikely that the length of the USB cable could influence the sound.

Corrupt firmware updates  would result in a not functioning piece of equipment. 

you know more than I do. I only reported what happened. install 2wice with my desktop and 5m USB => unmistakably horrible sound.  then reverted to 4.4.

3rd time, re-installed 4.6 using a measly dell laptop and a much shorter USB => horrible sound definitely gone - but a very 'different' SQ from what I was used to with 4.4.

I cant pretend to understand what's going one here -- maybe someone who knows more can shed some light?

Something that hasn’t tot anything to do with an USB cable. Sorry, but from an IT point of view it maken no sense at all. Computers don’t have feelings or mood swings. It is binary: it workshop or it don’t and that will be consistent. You must have done something different in the order or nummer of steps.

I don’t doubt what you are reporting, I don’t think it is accurate without you being aware of it. And thus urban myths about the length of the USB cable influencing the firmware update and by doing so influence the sound of a streamer come into being.

yes, exactly correct. the something different that I did was to use a shorter cable and a different PC for the install.

I repeat, for the umpteenth time - I am not claiming to understand what caused the difference in the result here. I simply don't know.

For best sound quality from the 4.6 update you need a 3cm usb cable made of pure silver.
