Yes but let’s dive into the “root” of your question. “Can I get better”? and “How”?
You’re thinking too simply that you rip and format are going to give you better. Let’s get more generic than that. I’m assuming that you have an SACD player and that is cabled, analog of some form (RCA / XLR), into a pre-amp and then out to your amp and speakers.
OK, let’s take apart that SACD player. That’s an “all-in-one” component that holds media (SACD), a way to read it (laser), a way to decode it (processor), a way to convert it to analog (DAC), and a way to send it out to your pre-amp (output stage). I can guarantee swapping in better gear at each one of these individual components will make things sound better. So what does a Roon DSD set-up look like?
Media - You’ll want to rip the SACDs to something like DSD files onto a drive. Plenty of posts above on various ways to do this. Now, you’ve changed your media into something infinitely more flexible than your plastic SACDs.
Processor - This will be ROON and a network transport format (RAAT). RAAT is bit perfect to the media so you’ve removed any coloration the SACD player was injecting at this step.
Renderer / Streamer - This is new to the chain and may be embedded within the DAC. This device sits on the network and takes RAAT (above) and prepares it for the DAC. In this case it will be extracting the bits off the network (RAAT) and preparing them as DSD for the DAC.
DAC - This is the biggest benefit in ditching the SACD player. While many SACD players are fine bits of kit the ability to get so much more detail and timing from a stand-alone DAC will be the night/day difference you’re looking for. Also, sky is the limit on upgradability here and everything around the DAC can stay the same. You’ll be amazed at how much a DAC will change your whole world and system. This should be the central point of your research and purchasing decision. You’ll want to make sure that you’re looking at native DSD DACs.
Output Stage - Every excellent DAC will have an excellent output stage. Match the connection type that you’re already using (RCA or XLR) and the rest of your system is ready to go. Or, if using RCA, some will tell you that XLR is the double-cherry on top to the whole system and is an “upgrade” worth purchasing.
Anyway, that’s the way I’d look at it. Separates all the way and ditching the SACD player just gives you better opportunity for more separates.
