D250 to D800 or upgrade to D250 pro CI?

[audio_engr]

For about the same amount of money i could do following:

• Buy another D250, use it as slave and have a D800
  
• Upgrade my current D250 to a D250 Pro CI
  

My current D250 is Roon Ready. I only use this source to listen. Considering I have 802 D4 speakers, what option would have the highest sonical improvement? The benefit of the upgrade would be also an extra 2 year warranty. My current listening levels are mainly between -30dB and -18dB. The sound is already amazing but I was wondering if i'm missing out something without selling a kidney.

I am very familiar with your speakers and also the D250 sound characteristics. I will definitely say that if streaming is your primary source (like mine), it is worth every penny the upgrade cost and get your D250 to Pro-CI level. What you will gain are on several key areas:

- You will hear a much more detailed top-to-bottom sonic structure that initially will sound a bit forward but as time settles in, you will grow with it as it will offer a more holographic soundstage that is bigger in size. 

- You will get better micro details and the dynamic contrast from soft to loud is excellent where your speakers are champions. 

- The top end of the frequency response will also allow "air" that your speakers again do well.

- The soundstage on the overall is more black.

{ i had the D400 with my 802d3 since 2016 & when I went to 440 Pro-CI in 2018, i immediately saw all the above I mentioned } Just for info, my listening levels on the Devialets are -12dB for Rock/Pop/Jazz and -8 to -4dB for Classical & my music is 70% classical. I recently last month attended the Capital Audio Fest CAF 2023 in my area & saw a lot of new gear. The only amps that reminded me of my Devialets were the huge $$$ darTZeel amps. I think that says a lot for Devialets.
