Crown MA-2400 amps vs Emotiva XPS-5
Posted 04 December 2013 - 11:11 PM
I'm not sure if multiple MA2400s would do the trick better than the Emotiva, after all they only need to amplify a signal and these do the job very well. The Emotiva has great reviews but I'm a bit old fashioned. My amps are not in the same room as the TV so sound is not an issue. I like having the pro build mindset as the MA2400s are bulletproof, have tons or power, are cheaper to obtain. I was always told the best equipment is made in Japan or USA. I understand the antiquity of this statement and it may juvenile, does it still hold water? I wouldn't purchase a chinese car even if it was designed in the USA (standards are standards!)
I look at the build quaility of the Crowns, the design, the specifications. To me, each channel should be as independent or other as physically possible. The emotiva share a lot of commonality throughout the amplification. I'm not sold that class D can compare to the Class AB of the MA line.
What would the board suggest? I know these crowns are old tech but they still make virtually the identical amp in the MA2402. How bad could it be? It may be overkill, help.
Thank you for looking at a dumb question from a NOOB!

When you compare gear it's very important to AB them carefully (one set of speakers, same gain and other amp parameters, not driving them to much (other wise you're just comparing the sound of the amps current limiting), as few A/D D/A conversions as possible, good grid power for both amps and many more variables), if you compare good quality amps (no matter the topology) you'll almost never hear the difference (sub duty amps excluded). So if you have the amps in a different room (huge plus, no need for K series) you can just buy more "big irons" (older heavier amps), they will have enough muscle for all your sonic needs without ripping your wallet. The down side to using old irons is that they will probably be a bit less reliable then new amps.
You shouldn't care about the amps damping factor that much, what you should care about is the whole system damping factor. The amps damping factor is pretty negligible when you use short 10AWG speaker cables and 8 ohm speakers so just do that and forget this spec ever existed.
Look here for further explenation:
To the best of my knowledge the MA-2402 is discontinued as well.

The old class D bad reputation comes from 20 years ago when it was not perfected yet and mostly used for doubtful car amps. Now, even entry-level Crown XLS is as hifi as one needs, imho.
