Consider buying used B&K amps, especially mono blocks. For example M200 Sonatas. They have a warm tuble like sound, can drive anything, very high current 150 amp peak and are very inexpensive. I've seen them sold for as little as $550. IMHO your quality of sound per $ is extaordinarily high.
B&K ST2140 or Odyssey Stratos 150?
Would the law of diminshing returns apply here? The Stratos is twice the price of the B&K but does it neccesarily have twice the quality in sound? And what about if something goes wrong with the Odyssey while B&K has been around for 20 years. Just trying to make up my mind here and save some money if possible. Any suggestions would be greatly appreciated as Odyssey amps cannot be auditioned until and after you have paid for them whereas the B&K is available at a local dealer. Thanks everyone.
