Reference Theater Series IPS-1 Conclusion

by Gene DellaSala last modified May 30, 2007 22:40

IPS-1top.jpgThe Emotiva IPS-1 7CH amplifier has proven to be a solid performer. It’s a cool running amplifier that doesn’t need a great deal of ventilation under most operating conditions, making it ideal for shelf or rack installations. This amplifier can be utilized with moderately efficient 8- or 4-ohm speakers and will likely drive them with more composure and grace than comparably priced receivers and certainly as good as any dedicated multi-channel amplifier in this price class. In fact, one of its closest competitors, its own big brother the MPS-1, is very similar in design to the IPS-1 but has more power and completely independent card based modules and sells for mere $500 more, but I actually think I prefer the cheaper, less powerful IPS-1! The IPS-1 is in a more manageable form factor making it easier to transport and setup. The IPS-1 has about a 2dB lower noise floor than the MPS-1 thanks to the absence of a limiter circuit. You can also beat the snot out of it without fear of the amplifier shutting down. I felt both amplifiers sounded much LARGER than they measured or their price tag indicated and believe either unit would serve as an excellent power center for all but the largest scale home theater installations.

From its excellent sonic characteristics, to its no-nonsense build quality, fit and finish, Emotiva has once again demonstrated via the IPS-1 that you don’t have to break the bank to get quality electronics that rival many of the more well known brands at a fraction of the cost. If you’re looking for a solid sub-$2k multi-channel amplifier for bi-amplifying your stereo speakers, or for powering your sophisticated 7.1 channel home theater that won’t falter on tough power demands, save $800 bucks and buy the Emotiva IPS-1. Your ears and your wallet with certainly thank you.

The Score Card
