Beautiful quartet, all the parts get a chance to shine. I am a cello, so I love the first & second movements - not easy for grade 5 me, but I am determined to master them. I have even been known to do some practice at it !
NB the cello part includes some treble clef (usually played an octave lower) so unless you are fluent clef-wise, you need to download the 'dvorak conversion kit' from http://www.acmp.net/dvorak/ which gives you the 'false treble' as paste-over tenor clef bits.
In summary, tough, but worth the effort.
