i own about 10 of the shm cds and have been extremely happy with all of them.they are,to this point, better then previous copies of the same discs by other production runs.the 'boston' disc i recently purchased is superb..much better then the sacd of the same disc.the rubinstein 'chopin concerto' and the rubinstein 'tchaikovsky-rachmaninoff concertos' are both superb.the chopin is the equal to the sacd of the same performance i have by the same pianist. are they pricey..?...relatively yes, but to alot of us ...worth it.regardless of what some pedantic members of this and other forums think, some cds are, on a system that can do them justice,superbly musically enjoyable and better then sacds on cheap systems that do not allow the full sonic capability of the discs to emerge.
