    "OK amplifier for low-impedance headphones"
    Pros - Excellent customer support, good value for entry amp, incredible battery life
    Cons - Inverts phase, low-end distortion, not enough voltage for high-impedance cans, DC-offset on output when turned off, channel volume imbalance
    I owned two PA2V2 and while it's good value amp, it had far too many flaws to my liking.
    Gary however provided excellent customer support throughout the whole time.
     
    Ended up with O2 and I'm happy so far.

    "superlative!"
    Pros - sound quality, unbelievable value for the price, battery life
    Cons - no bass adjustment
    current use is for watching movies / series on netflix on a nexus 7 tablet , though occasional use with a vintage sony 818 mp3 player.
     
    utterly spectacular analog-sounding output  via koss porta-pro´s , which makes a match to rival much more expensive stuff -  at least the porta-pro´s beat my other headphones , namely shure 530 , and sennheiser 280, which despite similar specs sound thin and lifeless , and gary explains why, and i quote him from an email (one of many always courteous, patient, prompt, unfailing) : "The copper wire that is used to wind the coil for the driver, they picked the right type of copper, thickness, and number of windings for the wire. The mylar material they used for the driver, (titanium coated mylar in later versions) much have been light weight enough yet still rigid to reproduce accurate audio. The holes in the back of the driver were enough to let the right amount of air pass through. Everything seems to have worked out pretty good with the Porta Pros, especially for the price. [ditto for the amp ! (my comment)] " .
     
    my wish for a bass adjustment is so that finicky headphones like my above-mentioned might be thus ass-kicked to produce decent sound :)

    "Great sound quality, battery and portable size"
    Pros - Great neutral sound, nice detail and wide soundstage, great battery and price
    Cons - Bass boost would be welcome, slightly bulky
    This amp has really sound quality , neutral side and wide soundstage . It could have a little more bass with bass boost switch but no complains here since i do prefer a neutral sound to get the natural performance from my iems. Battery is great , i still haven't charged it yet . I like the volume knob it is very easy to adjust . The output could be a little easier to use. For example when using my pk1 it demands some force to put it , and get it out of output . The size is portable but could be less bulkier. These are just very minor details but the conclusion is that for the money , this amp has amazing sound quality , amazing battery life and best of all the best support you can get with Gary being a very friendly persons that offers lifetime warranty for his product , either if it is your fault or not :wink:
     
    Honestly what else could you ask for ? 
     
    Very happy customer here
