I guess, before asking your question, you should have listened Accuphase or Esoteric and compare them with Burmester sound.Than you should buy one that you like most
As for the Burmester, there is not much to add. Superb sound, quality of construction, hand made in Germany, longevity of product lines, great factory support, if needed, excellent resale value, if you ever decide to upgrade. Of course, its much more expensive in US than in Europe
As for the cables, aldo you own Focal, I would not recommend Cardas anywhere in Burmester system. You will have time to experiment with that, but you should try their own copper based speaker cables (they make silver as well). You will get their (’silver’) power cable with amp, no need to change it as well. Burmester sounds best when all components are theirs, depending on your source and power conditioner, you may consider adding more their stuff later on.
In any case, sleep in peace, Burmester gear is a great stuff
