Will a PS Audio Superlink DAC Improve My Sound


My existing system is used exclusively for stereo listening and includes:

Anthem Integrated 225 Integrated Amp - 225 wpc
Marantz CD6006
Sony SCD-XA777ES CD / SACD Player
PC based server, equipped with a Creative Sound Blaster Audigy SE Sound Card
Paradigm Studio One Reference Speakers -Studio 100 v5
iPod Classic

The CD6006 can be accessed via the USB input for hi-res WAV files on a USB stick, thus the 6006 can becomes a hi-res audio player.

The Sound Blaster Audigy: 24-bit/96kHz audio resolution, 100dB signal to noise ratio, CMSS up-mixes stereo content to 7.1 surround

Now that you know what we are working with, can you tell me:

Will the PS Audio Superlink DAC will improve my system’s sound? 
The iPod has a built in DAC, but how good is it compared to the Superlink?
Will the Superlink improve the sound of my server given that the sound card provides 24-bit/96HZ resolution?
When using the USB stick in the CD6006 will I see improvement on that sound?
Is there a better DAC that I might consider for a low end system such as mine?

Please excuse my ignorance, as I am a virtual newbie in audiophile. So this is a learning experience for me. Any advice or recommendations you can make would be greatly appreciated. Thank you for taking the time to view my post.

Thank you Mark. You solved my question. I need to increase my budget and go for a more modern DAC. Thanks for taking the time to consider my question and to respond.  I appreciate it.
i am unfamiliar with that particular model of PS Audio DAC, but I suspect it is quite outdated.  If your budget is $1k, I suggest a modern DAC.  I have the PS Audio Perfect Wave DAC mark II.  This can be found for about $1200-$1300 if you're lucky.  You can later add a Bridge II which will upgrade and modernize the DAC.  I am using this setup and it is amazing.  I run it with Roon software.  Have a look online and see what you think!
I have a $1,000 budget. I am not married to the PS Audio DAC by any means, it was just one of the brands I had high expectations. I have an Essence DAC on my PC based system in my den, and am pleased with that. I just want to see what other's experience's have been before I purchase one for my main system in my living room. Thanks, for your response.
May I ask why the superlink? It seems quite old, and you may have better options.  I own a PS Audio DAC myself, so I am a fan, but I am weary of such an old digital product. What is your budget for a DAC?
