Ok got it, and installed, again thank you!!

post #677 of 807

Resonessence labs have released the next software update. 6.2.1

 

It fixes the clipping which occurs in the differential headphone output mode.

 

I raised the issue alittle over a week ago and they were very quick to fix the problem and push out an update :D

post #678 of 807

I just installed the latest beta software (6.2.1) on my Invicta and was curious to see just how much the differential HP output was actually improved.   My overall impression is that the overall sound in differential mode (using HD800 phones) does seem to be significantly better compared to what I remembered prior to the upgrade.   I'm not sure how to translate what they fixed (clipping, other?), but the amp seems to be a bit more resolving, perhaps with a fuller more robust, and dynamic presentation -- exactly what you might anticipate using headphones in balanced configuration.   It's a very welcome improvement indeed, and I think it now makes the Invicta's amp easily competitive in differential/balanced mode with other top-tier stand-alone headamps.   Having just purchased the extremely good Questyle CMA800R amp to pair with my Invicta, and comparing the two, the Invicta's amp is now pretty much the equivalent SQ-wise to the Questyle (SE mode), and perhaps even better in some ways (slightly more resolving).  For anyone already owning an Invicta and considering purchase of an external amp (in the $1-2K range) -- before doing anything, please install the 6.2.1 upgrade and see how you like it (in differential mode -- you will need an xlr-trs adapter).   It may dissuade you from making an unnecessary purchase down the line.   I'm not saying an external amp would not be an improvement, and I think for some difficult to drive planars, you will probably still need more power, but for most dynamic phones - HD800, etc - the Invicta may be all you need.

Nice! I'll have to apply the update to my original Invicta before it moves on. Love the Invicta Mirus, but I do sometimes miss the convenience of having everything all in one device.

Additional thoughts re comment above:  based on more extended listening to both the differential output of the Invicta HP amp (with latest firmware/software updates) and Questyle CMA800R (single ended), and going back and forth between the two, I continue to stand by my impression that the update has improved the differential output on the Invicta amp, however I feel that the CMA800R is still the better amp -- more refined, less "congested" and offers slightly better imaging/soundstage.  Low-level resolution are excellent in both amps and are probably equivalent, although the Invicta amp's upper register output with the HD800 seems slightly tilted upward, which on some material will create an impression of more "detail" compared to the Questyle, which actually has the more balanced presentation of all frequencies.

I've been trying the last several 6.xxxx firmware beta updates for the last weeks and I have several questions to ask :

 

1) For starters, is it just me imagining things (this is the most likely probability) or do you feel the SQ has slightly changed (not just the balanced amp mode) ?

 

2) Can you hear a high-frequency hiss coming from the front OLED screen when it is on ? It's very easy to assess by simply switching it on or off with the remote (long press on the "menu" button). I find that the intensity of the hiss is correlated to the size of the characters being displayed (therefore it's stronger when displaying volume for example) and the brightness of the screen. Perhaps it has to do with the change in brightness steps available in settings (it used to go from 1 to 15 I believe, now it goes from 1 to 10) ? Perhaps it's just me, I can get annoyed by fridge buzz, my Apple Airport, the Apple TV's powered on hiss / buzz, this kind of thing. I've now gotten used to switching it off as soon as I'm finished changing settings, volume or navigating to avoid hearing it.

 

3) When switching the OLED screen off, it frequently only gets partially off, i.e. a part of it remains on, either the top half, or the left top corner, etc. I have to turn it back on and off to have it fully off. Do you share this experience ?

 

4) When using dimmer settings than the full brightness OLED setting, and particularly very low brightness levels where it's the most noticeable, the display is unevenly lit. What I mean is that some OLED cells will appear brighter than others. Sometimes, it's several lines of pixels that will be brighter than others, or columns, or a mix of both. 

 

5) The rate indicator, which is as bright as other LEDs when using the SD card, is much dimmer when using either the Toslink or USB inputs, except when I press buttons on the remote, in which case it gives me a sort of "flash" at the correct LED brightness. Yours too ?

 

6) The volume changes at different speeds when using different inputs. I think it changes faster when using the SD cards than when using USB for example. Is it the case on your Invicta too ?

Good question -- I do believe there is an overall improvement in SQ (perhaps subtle but real), both in the differential amp mode and also via the xlr output to my external amp.  However since I'm not willing to undo installation of the beta update just to confirm this, I could not rule out that the perceived improvement is more subjective or even wishful thinking.   Assuming there really is an improvement in SQ, it's hard to see how fixing clipping in the headphone amp (as mentioned in an earlier post) would also apply to the XLR output from dac, unless there were indeed other internal firmware/software update that would have been applied across the entire dac.  I think this could very well be the case.  

 

2) Can you hear a high-frequency hiss coming from the front OLED screen when it is on ? 

 

No, I hear absolutely no hiss from the front OLED screen regardless of the brightness setting.

 

3) When switching the OLED screen off, it frequently only gets partially off, i.e. a part of it remains on, either the top half, or the left top corner, etc. I have to turn it back on and off to have it fully off. Do you share this experience ?

 

I have not tried doing this -- can't offer an answer.

What I mean is that some OLED cells will appear brighter than others. Sometimes, it's several lines of pixels that will be brighter than others, or columns, or a mix of both. 

 

Haven't really noticed this at all. 

 

5) The rate indicator, which is as bright as other LEDs when using the SD card, is much dimmer when using either the Toslink or USB inputs, except when I press buttons on the remote, in which case it gives me a sort of "flash" at the correct LED brightness. Yours too ?

 

I only use the SD card and not other inputs, so I can't really answer this question for you. 

 

6) The volume changes at different speeds when using different inputs. I think it changes faster when using the SD cards than when using USB for example. Is it the case on your Invicta too ?

 

Same answer applies as above.  Also I have now decided to use my Invicta only as a dac for my external amp.  The software update allows you to internally set a fixed output level, which is what I now do, and control the volume entirely from the external amp.   Interestingly when you do this, the OLED display will show the upsampling rate and not the volume.  

post #683 of 807

I have made the update of the firmware to 6.2.1 a couple of hours ago.

 

I am just using my Invicta with headphones (Sennheiser HD800) in differential mode. Haven't tried, any other combinations.

 

About the sound over my headphones, in differential mode, the loudness has clearly lowered a few DBs, as I have to set the volume higher than before.

 

I feel a bigger change than when I first used the differential mode against single ended, after the feature was made available.

 

I feel that it has larger dynamic range now. More slam.

More detail too.

 

My HD800s are now feeling more analytical and less musical with Rock and Pop, but classic Jazz is actually sounding better then ever.

 

Need to listen to it for a few more days, to get my ears/brain used to it, and maybe revert to 5.2.2 again, to get a better idea.

 

After that maybe an email to Resonessence Labs to report the experience and ask if they could provide a little more insight about the changes.

 

 

P.S. Maybe the Invicta is now more Planar Magnetic friendly and less HD800 friendly!... which is actually the industry trend, right?...

I've taken some pictures to better explain what I've noticed about the OLED screen and LED brightness : 

 

This is what my OLED screen looks like when brightness isn't at maximum value. Here, I suppose it should be around 3 or so : 

Basically, some areas are brighter than others, but they aren't all the time brighter in the same area, it depends on what's being displayed. The bright horizontal bars on the numbers 4 can very well be darker than other areas when displaying something else.

 

And that's the brightness of the LED indicator rate in Toslink and USB inputs, basically dimmer than it should :

 

Compared to its brightness when using the SD card :

 

Are you experiencing something similar ?

Here the OLED display looks the same as before, except for the font size used in the menus.

Regarding sound, adding to my previous impressions, everything looks to have been moved away from the headphones.

To clarify : my OLED display has always looked like that regardless of firmware at lower than max settings. Does yours also look unevenly lit when using low brightness settings ?

Sounds like you have a (minor) hardware issue going on there. I'd shoot Resonessence an email about it. 

post #689 of 807


Have adjusted my OLED Brightness to 2, and it shows the same levels of luminance across all pixels.

An email will be on the way soon. Thanks for your answers !
