This is THE set of Mozart piano concerti to have. I've always wanted to have this set, and I now I can have it for a song. I'm listening to KV 503 and I like Perahia's cadenza. No pressing problems with my set (made in the EU). What a glorious set at a budget price. I'm OK with no notes as the price is so low. How lucky we are that Murray Perahia made these recordings before his hand injury.
