I have a relatively small dedicated room which I have measured using REW and subsequently treated with the excellent help of GIK Acoustics. The system sounds good but there are (still) some problems, in particular with controlling the bass of my Sonus Faber Olympica Nova IIs.
My dealer suggested to try some other speakers as he thought the Olympicas were the weakest link in my system now. So I had a home demo of Magico S1 mk II and Wilson SabrinaX.
To cut a long but very enjoyable day short, I have placed an order for the SabrinaX. I don’t wish to engage in too much hyperbole but these speakers have pushed my system to a place I didn’t think existed, or at least didn’t think would ever exist in my home. I am absolutely delighted and any doubts I may have had at times about spending vast sums of money on all this hifi stuff are gone.
I think this is probably the hardest part of the hifi journey - finding speakers that complement the rest of your system AND have synergies with your particular room. Upgrading black boxes is the easy part.
