I would agree with the above but Vandersteen and Thiel were left out. These companies have been around a very long time and consistently offer good products. Vandersteen especially offers excellent value for the money spent. ARC also offers cutting edge products, dependability, solid engineering, product support for all products ever manufactured. I still think their D series amps and SP series pre-amps compete with the best I have heard in the past 10 years and they stopped being manufactured over 10 years ago. Market acceptance of a product year in and out is the real indicator of how good a product is. The above products fit that bill.
