Upgrade DAC Power Supply, Streamer, or ?

I used to have an Innuos Pulse but then after I obtained an Accuphase DC-37 Processor/DAC I upgraded to an Innuos Pulsar and the SQ is extremely noticeable.  I recently reached out to Sean Jacobs who designs the power supply for Innuos and he will be making me a proper power cord to replace the Innuos factory cord.  If anyone understands power supplies it's him! I'm actually thinking of having him build me a power distribution block for my system. Anyways, streamers make a significant difference regardless what others might try to tell you but a really good DAC coincides with a really good streamer.

Re using the AI-bots. I am using Gemini and Microsofts co-pilot and are copying the respective answers forth and back. It actually helps a lot in understanding what to prioritise. They starting themselves the dialogue about pure stats vs audiophile and "there is more to it than just numbers" :-)

Innuos, I have both the Pulse mini and Zenmini Mk2 and a LPSU. I am very satisfied particularly with Sense, which I prefer to Roon. I have started using Tidal Connect for convinience, but that gives some problems. My systems are having challenges figuring out, "who is in charge" and now and then I am unable to access any of them. 

On a well evolved system, power supply upgrades from a cheap wall wart to a well designed PSU offer a logical refinement.  I’ve done mostly DIY power supplies, but have never upgraded to an expensive brand name unit, so am not sure how much more you gain by going that route vs a more generic upgrade. I suppose it depends on the system.  My view is that a good generic linear regulated PSU upgrade might allow you to do both upgrades, which could put you further ahead for money spent. 

I would say, before you change anything about any of your equipment, get an Ametek Powervar power conditioner behind all of it.  You can get it in a medical-grade with 20 amp outlets if need be.  Just adding this behind my PC, DAC and headphone amplifier immediately yielded a blacker background.  Now, granted my apartment shares a single 20 amp circuit for everything, so im a prime candidate for a conditioner.  But fidelity improvements aside, you'll want to protect your investment. 

As bigtwin posted, I also had a very interesting / informative "chat" with Chatgpt.

It started with comment I wanted to check regarding CD Redbook standard and ended up with me asking for an evaluation of my entire system.

Chatgpt broke it down logically, even told me the best method and why it was best for connecting my music server to my DAC ( AES ). I was given a checklist of settings for JRiver running on my music server. 

I am not familiar with your gear enough to comment on the upgrades.
