Radios aren't for everyone, and require a certain setup to sound their best. If your room requires a near field setup, they excel. Many of us buy used and if we aren't fully satisfied, or later find something we like better, and have some extra disposable income, we sell what we've got at a loss and upgrade. Sometimes we get lucky and sometimes not. I feel lucky to have found Raidhos. They work for me and are worth the price of admission (used). Are the D2s my last speaker? Who knows. But they sound better, to me, in my room than the YGs they replaced, and better than my previous Peak Consult, Piega, Genesis or Selah line arrays.
Every speaker, and every component, has trade-offs. For example, I can live with a rising top (I'm getting older and my hearing there is diminishing) but could never live with over-ripe mid bass. To each their own. We can benefit from each other's experiences, on forums such as these, but we can't hear for each other...
