If you have multiple storage locations for your music and you have the same album 
in 2 or more locations JRiver will show that album 2 or more times.

 

 

 

If you copy music from another location to your CAT Music Drive ensure that the 
same music is not on that drive or you will get duplicates.

 

  

 

If you have a lot duplicates files the best way to solve the problem is to use 

PerfectTunes

 

software.   
 

PerfectTunes

  is installed and configured on your CAT.  It is located on the desktop.

 

 

You can also use Windows to delete duplicate files. 
 
You can also use JRiver to delete duplicate files. 
 
With the JRiver version 20 that is installed on your CAT JRiver will automatically update any 
files that you delete using PerfectTunes or Windows.  This is a brand new feature and no 
longer has to be done manually as in the past. 
 

12)  Playback of DSD files with the 1543 DAC 
 

The CAT  is configured to achieve the best sound quality possible with PCM and DSD files. 
 
The CAT can play 

all

 file formats including DSD file formats.  It does this by JRiver 

converting the DSD format to PCM format -> "DoP". 
 
In our opinion the best sound quality from non-DSD files comes from using the "Ultrastream" 
setting in JPLAY, so it is configured that way from the factory.  (You can of course try other 
settings). 
 
With DSD files we find that JPLAY generally cannot be configured to "Ultrastream" and that 
the "Xtream" setting should be used.  Do to the extra computer processing and increased 
latency of the DSD to PCM conversion the music may stop or stutter if using the 
"Ultrastream" setting in JPLAY.   If you have issues you can also change JPLAY from Kernel 
Streaming (KS) to WASAPI with DSD files. 
 

13) Using the CAT as an Audiophile NAS / CD Importer 
 

The CAT has been optimised for connection to a USB connected DAC, but it can also be 
used as a Ethernet connected audiophile NAS / CD importer.  Once the CAT is connected 
to your local area network (LAN) by Ethernet Cable 

any

 networked enabled playback 

device that is 

also on the same network

 can connect to the shared music drive on the 

CAT and playback the music on that drive.  Compared to typical computer based NAS 
drives the CAT will perform extremely well.

 

 
 
14) Specifications 
 

The CAD Audio Transport (CAT) is designed to work with the CAD 1543 MKII DAC and other 
USB DACs via USB connection.  It can also be used as a NAS/CD importer/server.
