TurboTom:
As @sorenkir reported, installation of the firmware works okay, though not as described in the instructions (Menu -> Storage -> Upgrade -> File Path -> select "Removable USB Disk -> select firmware file (check circle) -> OK -> Upgrade). The "Upgrade" function directly in the main menu (still) doesn't seem to work.

Fan speed mod gets reset as mentioned, moreover the broken "Flattop" FFT window file gets re-installed, so to correct this, the window file needs to be replaced again as described here.

Probe scaling factor appears to be corrected in the decoders, so that's a  :-+

Unfortunately, video trigger still appears to be broken (at least PAL and NTSC, I didn't have a source available for the higher standards).

I'm not certain if someone from Rigol checks this forum for bugs of their products or ideas for improvements -- I rather get the impression that this isn't the case. But I'ld consider it a great idea for Rigol to "give us" the 50 Ohms inputs since Siglent's "Counterpart" (I know some members will argue that comparison...  :-//) SDS1000X HD comes with them, and some may remember that the DSA800 series of spectrum analyzers all of a sudden got the 10Hz RBW with a firmware update after the SSA3000X appeared on the scene... And come on, repair the FFT windows functions, and what about a temperature-controlled fan? All the required hardware is there already.

Time lacked for more in-depth testing of the new frmware, but as yet it doesn't appear to be a game changer...unfortunately. At least, Rigol is still supporting the series.

Also upgraded without any problem. Extra options are still there. Had to re-apply the fan-mod.

Hello, nice to read this,
I am also interested in Audio Elektronics and used the Rigol DS1054Z (Hacked) so far.
For Decoding i have an 34Channel Logic Analyzer https://www.pctestinstruments.com/deutsch/
And the Software is much better to use than on Scops so no MSO Needed.

I was comparing DHO1074 against the SDS1104XHD and ordered me, @ the End, the DHO1074 because of the better Price Performance Ratio on Analogue Representation.

@Saelig
DHO1074                 900$
SDSSDS1104XHD   1399$

DHO1074 Has HDMI Out and better Screen resolution, also the 10MHz Clock Syncronisation capability (SDS1104XHD dont has it @all) becomes Handy with the Sigllent SDG2000X for Syncronisation
(My Eyes will not become better on my Age so i like big Screens ;) )

The only thing i would miss is the BodePlot ability but not for the Cost off Performance.

The Sinalgenerator for SDS1104XHD cost extra Money (165€) so not realy comperable.

The Logic Analyzer kost also additional 342€ for 16 Channel!

The Intronix has 34 Channel and cost 490$ .
Timing-Modus, Sampling-Rate: 1KHz to 500MHz (interne LogicPort Clock)
State-Modus, Sampling-Rate: 0 to 200MHz (Clock-Signal from DUT)
Sample-Puffer: 34 x 2048 Samples (Datakompression: 2^33 to 1 (Sample-Rate up to 200MHz))
Interpreter: see Attachment!



Now i need to wait to get the Sope delivered.

I really like the smooth waveform display on these scopes, especially when playing with memory depth and multiple, overlaying scans, combined with the really good resolution of the display. It's a shame that Siglent apparently didn't do better with their pixel-doubling on the SDS1000XHD. At lest, that's something that Rigol got pretty much right with their entry-level high resolution scopes...  :D

Definitely a decent choice for audio electronics!

This rubbish called "pixel doubling" by some peoples is a smoothing technique used by all manufacturers(including Rigol on DHO1K) to display a moving wave (pic1). In stop mode where wave is unmoved it is not visible. Not all people zoom on screenshots to search for double/triple /quadruple pixels :)
The thing that add an unpleasant effect on Siglent scopes (in particular on SDS1KHD) is the stair effect, remembering about 8 bit scopes (pic2). 
For audio electronics I will choose Siglent first, because of it's Bode plot capabilities. It can use two channels to analyze and generate Bode plots simultaneous on both channels on a stereo system (pic3).
That combined with it's easy zoom function to help observing low signals make him the preferred choice for audio.
I have both scopes and I like them both ...
