Expert 250 Pro and 1000 Pro

The problem is not the features or the bugs that we have discussed several years here. For me the concern/problem is about the support, if the amp is broken, if we need repair, spare parts and most importantly the configuration which is driven in the website.

From everything I have seen so far, the support is still excellent.

I bought an ex-demo D1000 some time ago. It didn’t have CI boards so early December 2023 I asked Devialet. They immediately replied offering to ship the amps and install the boards for free. I received them back in less than 2 weeks. Communication with the rep and service was excellent. 

To my surprise dropouts during streaming (including Roon, RAAT, UPNP) with CI boards was worse than without CI boards and worse than a D250 I have. Roon on windows 11 on dedicate i5-9400 computer. Reading on this site I saw about the gigabite network problems. I Amazoned a cheap 10/100Mb switch which improved dropouts from multiple to a few times per hour.  Installed ROCK on the computer and now the D1000 plays flawless without any dropout in weeks, not even on 192/24 files. I also have not had any dropouts on the D250, but I don’t use it as much.
