Very few audiophile DAPs that are actually in the affordable price range out there, and FiiO is one of them that makes high quality DAPs out there at a realistic price. Another one I'd recommend checking out @Logan is iBasso DX80, it's their successor to DX90 which I own and enjoy.

How interesting! I've always been looking for a music player that can replace my smartphone, thing just doesn't have enough memory.

checks price

Okay that is obscene.

All jokes aside, I had no idea there was such thing as a high end portable music player. Not for me, but still really cool.

It's not just that, there's a market that feeds obsession with portable highend amplifiers and dacs.

5

I was looking at their X1 model just for something to use other than my phone to help conserve battery life. I then found a 7th gen Ipod classic on craigslist and picked that up. First time I ever bought an Apple product actually however I hate using iTunes. Thought about rockboxing it but according to the wiki on the rockbox page it shouldn't work with the 7th gen. Is this bs or am i fucked with iTunes?

6

Fiio does make some good stuff indeed. I absolutely love my X5ii (with E12A).

I'd like the X7's touchscreen because a large music collection and a scrollwheel are not an ideal combination. However the Wifi and bluetooth are killing the deal for me. Some people obviously want all that connectivity, but I'm not one of them.

7

I'm afraid only classic iPod 5th gen supports Rockbox, but you can still convert FLACs to Apple Lossless, you're not compressing audio files when converting, just changing the type of container to the lossless audio goes into. Think of FLAC/ALAC as Zip/RAR. The 7th gen does have a better headphone output over the classic 5th which under utilizes its Wolfson DAC with an inferior headphone output, but if you want to get even better audio to power your headphones you can stack a portable headphone amplifier/dac. Also you can install an SSD and larger battery mAh capacity.

8

Is there a portable AMP/DAC you'd suggest? I was kind of looking at the E17k from Fiio but I'm open to other suggestions.

9

@Wendell what is with you posting that wall of text? Is it in honor of Trump becoming the next president of the United States? : O

Update: Oh I see you fixed it but man it is still a long load of information in that post. LOL!

10

If you're planning on using a headphone that requires a little bit more power over IEMs, I'd say FiiO E17k is a great affordable choice. If you're little bit more obsessive there are obscenely expensive alternatives out there that I personally think is overkill since you're not gonna be doing critical listening on a portable scenario.

11

I gave up on high end portable audio before trying. I just don't see it matching a home listening experience in a quiet room with no distractions.

That isn't to say I wouldn't try something like this given the chance (without buying).

12

Not if you're talking custom in-ear monitors. You can mold high end in ear monitors to fit your custom ear mold which creates a seal. Even the universal in-ear monitors, you can get comply foam tips to create a really good seal.

13

Walking in the park, at work (if you have the option to listen to music there), working in the garden, while shopping etc etc.

True, it's not going to make much of a difference on a bus, in a car or on a bicycle or when walking in a city during rush hour.
When I go riding my bicycle I tend to use a midrange Sony MP3 player with headphones that don't seal at all (so I can hear the traffic better) instead of my Hi-res audio stuff.

14

High end IEM is definitely on my list of things to try.

That is the thing. I feel I generally need to be somewhat aware of my surroundings while out. I don't know how often I would want to wear something that completely blocks outside noise.

15

@mythicalcreature

Put the KSE1500 in your list, it's the first Electrostatic IEM. Insane.

@EarthMadeOfGlass

Since you're gonna be using an external amp I'd also look into FiiO Kunlun E18 since you're only gonna be using it with an iPod Classic 7 through Auxiliary connection. It's cheaper.

16

Yes :) I'm aware of that product. Insane indeed. I know the price, I should not be tempted but I've always been interested in what they could have done with electrostat in an IEM..

17

The FiiO E18 is great. I am using that one with my OnePlus X. I also just got a FiiO X1 but I haven't tried it yet.

The X7 seems to be a killer device but ... the price, man.

18

What ever happened to your ciems, @Logan?

19

Hmmph .. interesting video this is.

More audio stuff on the Tek pls

20

Rock a E17K and really like it have the K5 Amp Dock and it makes sweet desktop DAC/AMP combo.

The X1/3/5/7 also works with the K5.

You should check it out. @logan
