Joeybooynj, my impressions are based on my Acapella LaCompanellas and today I got my Tidal Contriva Discera SEs and they will get installed tomorrow. I really want to see what I get with Universal Cells on the Tidals, but I can tell you that I will be unhappy to remove them to listen without. The clarity with them means that you will never remove them. The realism of the sound stage is awesome and the bass is once again better defined.
When you first put them in you will be very impressed but with time and break in you will repeatedly think that something good has happened. I will be further break in and I am still hearing it some three weeks after getting them.
