What's the general consensus on Crown pro amps for "audiophile" applications, especially the Class AB XLI series with the large toroidal transformers (rather than the XLS series Class-D amps that use DSP)?\n\nIf they are highly recommended and fantastic bang for the buck, would the XLI2500 be overkill? Since the LS50's seem to really love lots of power, would getting one each be overkill? What about the XLI1500?\n\nIf there is better out there and these aren't recommended, what would be options that really bring the most out of the LS50's? \n\nI got a pair of LS50 for $900. While I could get amps like the Benchmark AHB2, NAD M22 or the like for around $2500+, or amps like Peachtree Nova150 or Rogue Audio Sphinx and the like for about $1500, isn't there a general rule that you should put the bulk of your money into speakers rather than amplification? If so, it would seem like spending 50% to 250% more on amps for $900 speakers may not make that much sense.\n\nThen there are amps like the Outlaw M2200 monoblocks, NAD BEE series amp, Outlaw RR2160 receiver, etc. under $1000...\n\nWhat would be the best route to take? Wouldn't I be better off putting in another $2K into much better speakers than into an amp for the LS50's?\n\nLastly, what about the LS50W? Would that maybe be the best, most optimal option for the least amount? I hear great things about it because it's specifically tuned amplification for the LS50, as the engineers intended. But I worry about the reliability issues I've read about them... and I'd like to keep the speakers for longer than 5+ years, so it concerns me that the electronics could fail at some point.\n\nThanks in advance for your experienced input!
