Who here has gone from d200 to 400?

And what did you notice when going dual mono? Was it a big difference? would you do the same upgrade today? 

I was actually thinking of sending my d200 back to Devialet for the CI core infinity pro upgrade @ $3100 usd. But see that I can actually pick up a second used d200 for cheaper than the ci upgrade. 

And I do like the sound I’m currently getting from my d200 and focal aria 936’s, but always in pursuit of a worthwhile improvement.

Thanks for your any insight provided.

Mike
