The Emotiva amplifier linked would be suitable for the 4Pi in terms of power, but may not be the best choice due to its relatively high gain structure (32db). High gain amplifiers emphasize source noise and often have fairly high self noise that can be a problem with high sensitivity speakers such as the 4Pi. Power amplifier gain has steadily increased over the past decade from the de facto standard of 26db to as much as 10db more as low output preamplifiers (passives and some AV receiver pre outs) have become more prevalent.
