Yello I would first try 'The New Mix in One Go', an interesting album to say the least. Then 'Baby','One Second', "Motion Picture' and 'Stella' in order of prefererence (Baby the best...)-all good albums. All are exceptionally well recorded, each will give your system the 'stretch' of its life and also give lie to the 'all music post-1975 sound bad' idea from certain circles.
