Hi Hanna,
the only harps I tried for a bit (at an harp festival) are the Ogden and the Hermine, I don`t know about the others, so I can only share some thoughts with you.
First, why did you sold the Livia? 😀 I tried it and it sounded really sweet.
I know some people say that an used harp sound better than a new one, but If I had to take a new harp that I will keep for a lifetime, I would go for a new one (like I actually did).
Lots of people praise the Ogden and also the Troubadour, but I wasn`t so impressed when I tried them.
Probably because -as far as I know- those harps have the same string tension and spacing as the L&G pedal harps, which is a good thing for people that want to go for a pedal harp, but I found it a bit unconfortable, and the string tension is just too much for me, even If I suppose you`ll get used to it at some point.
I remember the Camacs sounded lovely, but I don`t remember exactly the sound of the Hermine, the one I tried and liked the most was the Melusine, but in the end I felt in love with the Dusty String ones which I believe they have the most beautiful sound 🙂
