Don't worry about that as I'm not really "debating," I'm just sharing hardware info and more importantly, on the software, I'm saying (and really not up for debate on my end) that it is highly likely a bad idea when an Apple user uses something else, and as was my personal experience, also applicable when done the other way around, ie, a non-Apple user starting on Apple (not everyone is like my brother who, being a programmer, easily goes from his Macbook and iPhone then onto his gaming PC with no sense of having gone through some paradigm shift that ripped the space-time continuum).
The thing is, if ripping the CDs is already daunting now wait until you have to deal with anything that isn't iTunes. I'm just trying to save you time, money, and energy here, quite like the reason for that Hemingway quote.
I'm not an Apple user, per say, as I have used Apple machines and PCs for decades, mainly to access, other, different machines. It's all the same to me. I adapt to whatever machine I'm using without a lot of complaining that this machine is better than that machine.
Ripping CDs is not daunting to me, it is just a tedious chore that takes away from other things I need and want to do in my life, those things being, one, writing software to earn an income, and, two, playing music on my classical guitar.
Anyway, at least this discussion has spurred me to implement a $25 solution to hook my iMac 5k to the DAC in my Accuphase CD player through the use of a Toslink cable with one of those little $5 3.5mm mini jack to optical adaptor plugs. I had this setup at one point and then lost it when I upgraded to a new machine and moved so that my Toslink cable became too short, LOL. I can control iTunes with Apple's remote app all through Wifi, so that will be fun.
I suppose I would enjoy the MojoPoly but I'm not sure how much better would be the sound quality when dealing with a noisy environment such as that present on a subway, bus, or an airplane. I don't spend that much time these days listening on portable devices as I no longer lose time commuting to an office. The passive noise reduction of the Etymotic IEMs is nice, I use the big yellow foam plugs, and they make quite a difference in sound quality.
Perhaps I should just be happy with what I have without feeling the need to put down another $1000 for a portable rig such as the MojoPoly. I'm still up in the air about it all and appreciate people's comments on this thread. Thank you.
