Well i had a home demo of the Burson Soloist, RWA Corvina and V200. Two weeks for each.
I was least impressed with the V200, because although it had the most presence and vividness, it sounded too thick and undetailed at times with a kind of hardness and almost glassy quality to it.
The Soloist had superior clarity and made to V200 sound muddy by comparison, but for me the Soloist lacked some "natural colour". A bit pale sounding.
The Corvina seemed to have just as much clarity / detail, but had that slight colour and sweetness I like. It was my favourite by far. The only problem was it sounded crap at higher volume with my lcd-2 r2 (had the single ended version). Would love to hear the balanced version.
For me its either going to be the new Decware Taboo MK III coming in spring or the new RWA Cassabria that replaced the Corvina. I guess this will be an improvement over the amp section of a balanced Isabellina. I'm surprised it hasnt been mentioned it on headfi yet.
