Are higher end preamps worth the investment when you are only streaming Tidal & Spotify ?

OK, to the crowd that is voting preamp I am scratching my head. I have a Marantz surround processor and a dedicated Sony Signature TAZH1 ES that functions as a DAC/preamp/headphone amp. It is a cost no object dac/pre from the best engineers at Sony and was 5 years in the making. It sounds transparent as anything, but not "better" than my Marantz unit on 2 channel, just different. What is this preamp that will unleash this magic?? How much do I need to drop?

Since I run 6 different sources on my system, I would be sh*t out of luck without my preamp.

Counter to most views I agree with fuzztone. Recently my US $ 5000 pre developed a hum problem so I hooked my power amp up to my Pure Audio 5 Lotus DAC using it as a preamp. The SQ was excellent - detailed. good imaging and soundstage with no SS harshness. The SQ was if anything better than with the expensive pre and dead silent. So why do I need a preamp?

PS I won't reveal the name of my preamp but it is very highly reviewed and as always said to punch above it's weight.
