exceptional quality and diversity

Let us not choosy even if this box is not exhaustive of Decca recording !!
This collection of some of the finest performances in the Decca catalog of the monaural era would normally be self-recommending. Unfortunately, there are some classical music listeners who have difficulty hearing recordings in mono. In this age of surround sound that is perfectly understandable.
Nevertheless, I recommend this collection to the overall excellence of its performance and for its exemplary monophonic sound that mostly has a nice depth and a warm resonance from top to bottom, this case boasts Decca his surprisingly clear in his first records and maintains that excellence in recent years, which were just before the stereo nascent era. The collection starts with some iconic 1940 recordings of Ernest Ansermet.
The remastering is excellent: with nominal presentation, good dynamic range and exceptional clarity. In many ways, I prefer the sound of these recordings to those made in early stereo era, who always sounded little thin and hard in my ears. Here, mono sound is a rich and missing insurance early stereo recordings.
In addition it is also in their performance that these recordings are waiting to be heard. 1949 Petrouchka Ansermet (first LP record Decca) and The Rite of Spring urgent and dramatic with more appropriate intensity to the scene of the opera ballet. Of course, Ansermet is known for the large claims of "authenticity" in his Stravinsky recording. His Roussel, Ravel, Dukas and Debussy are just as good.
But the case is not a case Ansermet and the rest is of the same ilk

There are more, unlike a lot of big box like that, rarer works
-Jean Françaix (concertino for piano Feature Martinon London Philharmonic
The gingerbread heart -Baranovic directed by himself
-the viola concerto beck
-tontagel Arnold Bax conducted by Sir Adrian Boult absolutely great
-Namouma Lalo
In many other that could be cited (just look at the list of the cabinet works) !!

A superb job !!
