The price of the
Emotiva has dropped to $1600. Emotiva promises these power ratings:
300 watts RMS/channel; 20 Hz – 20 kHz; THD<0.1%; 8 Ohms; one channel driven.
550 watts RMS/channel; 20 Hz – 20 kHz; THD<0.2%; 4 Ohms; one channel driven.
300 watts RMS/channel; THD<0.1%; 8 Ohms; two channels driven.
490 watts RMS/channel; THD<0.1%; 4 Ohms; two channels driven.
250 watts RMS/channel; THD<0.1%; 8 Ohms; ALL FIVE channels driven.
According to
a review, it lives up to these promises.
The Rotel RMB1585 is no slouch:
Continuous Power Output 200W/Ch (All channels driven, 8Ω)
Total Harmonic Distortion (THD) (20Hz–20kHz) <0.03%
Why the large difference in cost, $3000 for the Rotel vs. $1600 for the Emotiva?
I suggest its entirely due to the way they are distributed and sold. Rotel sells through distributorships and retail brick & mortar dealers. There is a significant price markup at each of those levels. In contrast, Emotive sells by Internet Direct, avoiding the network of distributors and dealers, and their price markups. I wouldn't hesitate to buy the Emotiva.
Another option is the
Monolith 7x200 Watts, also sold online for $1600. It also sells by Internet Direct.
I wouldn't be concerned about this. All these amps are well designed and well built.
