Thanks all here's a quick summary
1. Special servers might enhance the outcome These are likely somewhat expensive and will increase the investment into roon by as much as 1000% (10 times)
2. Other services might sound better like Innuos at I assume a roon like expense
3. DSP equalizing might help dial it in I have no idea where I'd start though this is on my list (like roon) of things to experiment with and one person mentions some inexpensive ways to go about it Downside of course is a time consuming task with a learning curve
To me the low hanging fruit here is try other services and see if the sound stays the same as via the native Naim software, Not too expesnive and too much of a learning curve
