The GFA 5400 replaces the GFA 545II and offers many of the same design features and sonic attributes of the enthusiastically received GFA 5800 and GFA 5500. The specifications should adequately describe all the pertinent information, including the increased power output into 8 and 4 ohms over the GFA 545II. As the 4 ohm power indicates, the current capability of the GFA 5400 has been substantially increased. The improvements are clearly audible with virtually all loudspeaker systems and will be apprecaited by all who will use multiple 5400s in home thaeater systems.
With a 33% increase in power at 4 ohms, you might expect a substantial price increase. No way. In order to offer increased value, the suggested retail price will increase less than 10% (over the GFA 545II) to only $679.95.
