I think the whole of the Columbia classical catalogue is under-rated and overly-neglected. I love these Columbia reissues that Speakers Corner are doing and it would be great if the catalogue became as comprehensive as their Decca one is. Do you have the Speakers Corner Beethoven Triple reissue? Wonderful performance and very present, intimate sound (as seems to be a characteristic of many Columbia recordings). The Mendelssohn piano concertos with Serkin is another Speakers Corner Columbia I got last year and love (though some don't care for the performance apparently). And the Romeo and Juliet release - I now prefer that to my previous favourite - the Mercury Living Presence one!
Where are you buying them mate - in Australia or OS?
