Now that the Talich Quartet's survey of the Mozart Quartets is no longer available, this bargain box from DG is probably the best way to acquire the complete cycle at a modest cost. The Amadeus Quartet recorded extensively over the four decades of their existence (1947-1987). They gave us multiple versions of the best-known Mozart quartets, and many critics would argue that their earlier, monaural recordings of these works were fresher and more deeply considered than their later, stereo efforts (which is what we have in this DG Collectors Edition). As a longstanding fan of the Amadeus Quartet, I have heard all of their Mozart recordings, and am of the opinion that their later recordings are by no means inferior. The versions of nos. 14-23 included in this Collectors Edition are altogether superb: invigorating, yet gracious readings that manage to convey both the playfulness and the pathos of the music without undue frivolousness or schmaltz. The Amadeus' collective tone is robust, with a pronounced vibrato to which some listeners (particularly the historically-minded) might object. I find their sweet-singing tone enchanting, though some might find it cloying. The early quartets (among which there are a surprising number of near-masterpieces) are given no more or less than the weight they deserve; their rococo charms are undeniable in these light-hearted, but never condescending renditions.There is only one point on which I would caution prospective purchasers: The Amadeus are not generous with repeats. If it is important to you to hear the expositions of sonata-form movements twice, then you should probably pass up this set, fine though it is in other respects.The recordings have been effectively remastered; the sound is exceptionally vivid, with instruments closely observed. The upper register is smooth, not too strident at higher dynamic levels (as some DG recordings of chamber music during this period could be). In general the ten mature quartets, though recorded earlier (1960's), sound marginally more natural to my ears than the early quartets, which (if memory serves me correctly) are of 1970's vintage. No grumbles, then, about the sonics--this is one of DG's better efforts from the LP era.So if you're in the market for a complete Mozart cycle, do consider this set, which is attractively presented (though notes are rather skimpy) and economically priced. I prefer the Amadeus to the Hagens in this repertoire (the latter's Mozart recordings are also available in a bargain box from DG); I find the latter's interpretations superficial, though not everyone will agree with me on that point. The Amadeus were one of the great ensembles of their era, and I'm delighted that their Mozart is still available.
