    It seems to me that the sound one wants from a guitar amp is not the sound you want to playback recorded music.   In fact, they even sell different amps for regular guitars and bass guitars.    A musical instrument and recorded music playback are completely different animals.  But I'll reserve final judgement until I hear it.  

    Also, it seems like the market has largely abandoned stereo (aside from headphone/earbud use).   Don't we care about stereo anymore?

    And since there are no standards anymore, those wattage ratings are most likely meaningless.    Wattage ratings for amplifiers only make sense if they're accompanied by a frequency response +/- a given number of db and at a given distortion level.    But even ignoring frequency response and distortion, they can give a wattage number that's actually peak to peak.  So 100 watts peak-to-peak is 50 watts peak, which is 35 watts RMS.   But then you measure it at 3% distortion and it falls to 20 watts and at 1% it falls to 13 watts (although many guitar players like the sound of that distortion because it can generate square waves).   Etc.   And for an instrument amp, it's not the wattage that counts, but SPL.   It's even worse for A/V receivers because the wattage ratings are usually reported with only one channel driven instead of all channels driven.  
    It's so we can practice against a song we're learning.  Most modern amplifiers have an aux line input.  Bluetooth playback means one less cable with which to hassle.

    So far, I've ranged 5-11 hours.  Admittedly, the 5 hour session included the machine redoing the preview thumbnails for several thousand photos.  So far I'm loving my 15".  I do miss the "estimated time remaining" after the recent OS update.  I wonder if they'll add it back after they've addressed this issue.  It does feel a little CYA to remove a feature that's been there for nearly the entire existence of Apple laptops.  I'll be curious to see if my results are an anomaly or more the norm.
