Wen I listened first time the Børresen 01 at my dealer I didn't like, very dry sound and not so involving me in the music, I had the Raidho D1.1 at that time... Than, after 300 hours burning in the shop, they sound better, and after 100 hours more, better and better... I tried them at home and I bought!!! Now, after 500 hours they sound simply fantastic. I sold my D1.1... I suppose that the bigger 03 need even more hours to shine... I listened them in the shop and I loved, but they are too big for my listening room...
