Hello.
Can't see many posts recently I've decided to make one.
I own a Devialet expert 200 for a few years already ,using it with audio physic virgo5 .
I am happy how it sounds overall especially after adding some acoustic treatment to the room.
From some time I've got an upgrade itch .
So thinking of making one of these steps:
1. Upgrade 200 to 220 pro ci through devialet (most obvious. Cost 2100£

2.Upgrading my speakers to say Max up to 3000£ incl money earned from sale of mine also.

3.Investing about 2000£  into a mains conditioner plus power cable (thinking about Puritan audio here)

4.Another option I do think sometimes is to sell my 200 and buy D-premier (with the intention to upgrade it to 250 pro though devialet upgrade in couple of years time)
5.Any other suggestions?

What do you guys think?
Does any of you been in this situation?
What you've done and why?
Which move will give me the most ?

Thanks in advance for any suggestions...
