Violin Concertos

Could you recommend the best violin concerto recordings (performance & sound quality) you have ever heard by the following composers-Dvorak, Beethoven, Paganini, Mendelssohn, and Saint-Saens. Also, if there is any chinese audiophile on this forum, please recommed violin concerto Liang-Zhu (Butterfly Lovers). To me this is one of the most beautiful violin concerto, but I haven't seen any famous violinist recorded it. I have two copies, one by Yu Li-na, one by Sheng Zhong-guo. None of the sound quality is good.
