i have the ak70m2 & 300r as well but i haven't yet compared them because they both drain battery so fast they are never charged at the same time! so in that respect they are equal. :) but i think having both is useful. they both have balanced outputs and mostly support the same formats. the...

thanks! i actually have an ak70mk2 and i've put the 400gb card in it and moved the 200gb card from it to the other slot on the 300r. i just wanted to know that i'd be able to use the 400gb card as a backup or substitute in the 300r if necessary. tks to all who replied. glad i caught the sale. /guy

can the 300r use the sandisk 400gb micro sd card? reason i ask is that they're onsale at amazon and b&h today for $159. /guy

btw, the sandisk 400gb micro sd card is onsale for $159.xx at amazon and b&h. glad i waited a little bit--they were at $249, then $189 and i nearly bit then. i think it might be a one day sale. /guy

wow! what a detailed series of reports. makes your head spin. i did figure out enough of it to see that my sennheiser 6xx's are good for using with the player in environments where noise bleed doesn't matter. but then again, there's like 200 other headphones on that list which means their...

tks for the notice. i leave mine off except when i want to use it and thus i didn't know an update was available. only thing the changelog says is '.... system stability' although i guess you could get to better battery life from that premise. /guy

slightly off-topic, but i wanted to register my brief impressions of the ak xb10 bt amp which provides a regular 3.5mm stereo jack and a balanced 2.5mm trrs jack just as found on their players. or at least the ak70m2 which is the one i have. to digress somewhat. a few months ago i set out to...

i was skeptical of noise cancelling but the reviews i read said the sonys were as good as many other mid-to-high range headphones when plugged in and at that time i still had a couple of months to wait for my massdrop sennheisers. i was wowed by every aspect of these headphones from the...

i have the same sonys and the massdrop sennheiser 6xx which are the 650s and the sonys work perfectly via the unbal 3.5 jack and bluetooth. the sennheisers had a little less volume using the factory 3.5mm cable, but it was still adequate for me and i have bad ears and need a little extra. later...

hi folks: new to hi-res audio and balanced headphones, so be patient with a question i'm sure has been asked and answered dozens of times, but i think the ifi nano black is about the only dac i've heard of with an /iematch/ jack. i've acquired some fiio balanced iem's with a 2.5mm trrs plug...

i have the fiio f9s and haven't noticed any noise floor but then again i haven't yet tried tidal streaming. i'm unwilling to say the eq has no effect, but it had so little effect i abandoned it after just a couple of trials. i raised all the slider to the maximum and at most it raised the gain...

i'm on my 3rd case in about 3 weeks of ownership. i needed one right away so i got a miter case from amazon. it's actually not bad and has a folding panel on back so you can use it as a desk stand. but even before it arrived i ordered the ak one and it arrived a week later. but neither one of...

oh sure--one week after i purchased from amazon for full price. gee thanks. :) /guy

got my massdrop sennheiser 6xx headphones today and tested them using the default 3.5mm plug into the ak70 and was astounded how crisp and clean they sounded. i have some well-rated headphones, but the 6xx's were definitely a step above those. i could hear from 20hz - 16khz (pretty sure i head...

sorry for the multiple contiguous posts but this thread has pretty well dried up it seems. but i'll try some queries anyway. i never made it to the ak70m2 manual yet (i'm lying--i did read about 3 pages before i got sidetracked and learned that what i thought was a screen defect at the bottom of...
