A lot of the content on their website is generated by users here (and elsewhere) asking a good question. Since the question and answer are relevant they do some mild editing and post it on the site, so anyone else who had the same question can see it. Good strategy in my book. 

I agree that the XLR to TRS questions will important for many Invicta users who want to try out the balanced outputs and already have balanced HP cables with XLR connectors, and I hope that these can be addressed on the Resonessence website.  

 

When surfing around the web, it was fairly easy to find places that sold XLR to TRS adapters and cables - they are usually described as "microphone" cables but they all seem to have the standard 3 connector "stereo" TRS plugs, so I'm assuming this would be an acceptable solution for those who don't want to go the DIY route.  The pre-made cables don't seem to be that expensive either.  In response to a previous post, I assume the pre-made connectors would have L-R-Ground wiring done correctly.   As a "best practice" I would be inclined to stick with a fairly short length of cable (about 1 ft or less) and use good quality connectors.   There is also a Neutrik female XLR to male TRS adapter (sans cable) available but I would be inclined to stay away from this since the weight of the adapter plus XLR plug together might put too much stress on the phone outputs of the Invicta.  Perhaps Resonessence could make some recommendations on how/where to order adapter cables.

I'm fairly certain it will be the same adapter as the ones used for the Matrix Quattro DAC. You can find pre-made adapters at TamAudio.com that fit 4-pin XLR balanced cables or dual 3-in XLR cables. I linked to the a page or two back.

 

But yes, I'm sure Resonessence will provide the info, and maybe I can get a few cable makers on board offering pre-made adapters. I've already got an email in to Charleston Cable Company as they make a range of quality cables for good prices and can accommodate special requests. I'll update when I hear back.

4.0.0 firmware is now posted. This enables DSD playback (DSF and DFF format, from SD card or over USB) and also adds the fix for track numbers from metadata - no more renaming as a work-around.

 

The balanced headphone option, along with support for Asian test, will come around the end of the month.

Interestingly I just tried the update and the dac cant seem to read my .dff file of the SD card. It just says 'no valid' files.

I only have one .dff file to test for now. Will try some other ones later today.

Odd. They had been in beta testing for weeks and were fairly confident that no bugs existed. But you never know.

I'd definitely grab some more of the free DSD sample downloads that several different sites offer, and see if you have more luck.

I have my very own Invicta shipping out this week so I'll try it myself soon enough. My Auraliti PK90 handles DSD and I just picked up a 64gb SD card in anticipation of the Invicta so one way or another I'll be hearing some DSD tracks soon. All 5 of them....

I'm exaggerating a bit, but I really do wish there was more music available. I'll probably feel even more strongly once I hear some and love it.

I got one of the dff files from the 2l nordic website. It just doesnt want to read it. I'll fiddle a bit more once i get home.
post #277 of 694
So I have now tried several different diff files and the invicta still doesn't recognize them. I will keep trying but there seems to be some problems with invicta reading the dff files,
post #278 of 694

I can't speak for DFF, but I tried several DSF files yesterday on my loudspeakers and they all worked without a hitch.  (This may be obvious, but did you verify you have 4.0.0 by navigating to My Invicta?)  

 

I'll give DFF a shot at some point.  Did you find a free file somewhere?

As an aside, the DSD files sound *really* good.  The step forward from redbook to DSD vs. redbook to high-res PCM is much greater.

Project86, congrats!

HERE is a list of places to find free (legal) hi-res downloads, including several places with DSD tracks. I haven't tried the DSD options since I didn't have a DSD capable DAC yet, but some of the "regular" hi-res stuff is really great. 

 

Mark at Resonessence had mentioned how they had more trouble with DFF than DSF, but thought they had worked out all the bugs during beta testing. I just sent him the same link so they can find more test tracks to work with - armed with a variety of test tracks, I'm sure they will get to the bottom of it soon enough. 

 

On a different note, I was sent this info regarding balanced operation which is coming later this month:

 

 

It will be the standard way of doing balanced on TRS connectors.
 
Tip (3)  will be +ve
Ring (2)  will be –ve
Sleeve (1)  will be ground

I've already contacted Charleston Cable Company and have an adapter being made to convert my 4-pin balanced cables to dual TRS. At the moment I have balanced LCD-2.2, HE-400, and HE-500 available. Might be able to get some others down the road to try as well.

Wow, thanks for that.  I was only aware of Blue Coast Records.  Approximately how much does Charleston charge for the adapter?  I might be interested as well if the cost is reasonable.

post #281 of 694
Awesome thanks for the update project86.

On a side i did confirm that i have the 4.0 software on my invicta. Another strange thing i noted before upgrading my dac was that it took abnormally long to read the SD card whenever i had a dff file on the main directory. I would say it took a good 15 secs to read and give me my normal list. After installing the 4.0 software read times were back to normal (ie. Instant)

Channel Classics, the Dutch classical-music label, is also a good source for DSD downloads.

 

I bought the Pieter Wispelwey album that includes the Britten Third Suite for Cello Solo, which I already had as a hi-res PCM download.  It's the most realistic solo cello recording I can ever remember hearing.

 

I'm waiting for Pentatone, another classical label that releases pretty much everything on hybrid SACD, to start making DSD downloads available.  They have a really great back catalog.

 

I read somewhere on one of the audio-magazine blogs that some exhibitors at CES and T.H.E. Show Las Vegas were using DSD files of tracks from Santana's Abraxas album as demo tracks.  I'd kill my grandmother to get my hands on that one!biggrin.gif

Sorry, I should have posted this initially since it is an obvious bit of info.... Like all their cables, they offer 3 different tiers. Prices for a 1 foot adapter cable: $60 for the entry level, which is usually quality Canare cable. $95 for the mid level which uses Auric cable (from Audience AV). Top level uses Auric Ohno cabling and goes for $105. The mid and top level choices each use 4 conductors, braided, with no sleeves. Connectors are high quality Switchcraft or Neutrik.

I imagine Christopher will add them to his site one of these days.

Will look into it if LFF doesn't get back to me soon, ideally it'd be nice to have the adapter match my existing cable for the Vader Paradox.

 

The metadata fix doesn't seem to be working for me.  I have a Phillip Glass album on an SD, Etudes for Piano, and it still reads it as 1) Etude #1, 2) Etude #10, 3) Etude #2, etc.

RE the metadata fix: I too have noticed that the numerical sequencing as indicated in the metadata on some albums is still not working correctly, although on others it seems to work fine.   I would say that incorrect sequencing occurs in about 10-15% of the albums I've checked so far.  I can't figure out why this should happen unless it's something about the way the metadata itself was encoded during conversion of the source CDs, and the Invicta software can't read it correctly.  I have been using iTunes for the conversion my CDs to AIFF format.   I  hope this isn't a problem with AIFF or iTunes itself.
