Do I need a streamer?

Another vote for a dedicated streamer, especially with your excellent DAC.  A computer is about the worst source of streaming due to excessive noise, which is the mortal enemy of better streaming performance.  I started streaming Qobuz from my iPad, and adding even a low-budget iFi Zen Stream ($399) was a huge improvement.  You could consider something like an Innuos Zen Stream that along with being a very good streamer you can load your CDs directly into it.  In streaming, I’ve found everything can make a significant difference, which is both exciting given all the areas to get better sound but also a bit daunting.  Such is audio, but it’s well worth it and you can just upgrade pieces in stages, which is nice.  Hope this helps, and best of luck.  

Yep you do.

You don’t "need" a streamer, especially when you have not experienced the benefits. Carry on.

Most SQ improvements require an A-B compare for me to confirm. Not so when I hooked up my first streamer.

Night & day.

And I use Fildelizer.

@whitestix In case you didn’t catch this thread, there’s a wealth of info on it:

The key to good quality streaming from a general purpose computer is keep the “noisy” computer physically well away from the hifi gear by using a long wire to connect. Mine is a good 8 feet or so away connected by a long good quality USB wire and the results are very good, competitive with using the hifi streamer as the source. Also be sure to use a driver on the computer capable of doing higher res streaming. Default driver on a PC for example may not be up to the task.
