I would contact Dynaudio regarding warranty. Here in the states the warranty follows the speaker regardless if you are the original owner.
I owned C1's and later C1 Sig's for about 6 years. Great speaker. I had heard the Sapphires on many occasions. They have more forward sound. They are quite lively and punchy with deeper lows. Highs will be a bit brighter even though it has the same Esotar2 tweeter. When I first heard them all I could say is WOW. But in my personal opinion/taste I can't listen to them very long when playing them LOUD. Although both speakers have the same Dynaudio sound they are very different in the way the music is presented.
That said I haven't heard the Focus 340's. But I will say I have found that as you move up the Dyn ladder the sound gets a little more refined with each step up. Also Dyn should start shipping the new Contour 'C' series around October of this year. They are also working on an 'Evidence' monitor.
