KEF M100 (Gold) + FIIO X1 (Gold)

audiophile quality, easy too use

With the great built in DAC, the RCA output option and lossless format supported, this is an audiophile quality player. I hook it up to my Leben cs 300xs tube amplifier and it sounds great. I take it to work and use it every day. Highly recommended.

Great product

I purchased this to update to HD music capability that my two Sony walkman MP3 players didn't have. Fantastic build quality and performance in an affordable package. It drives my Sennheiser over the ear headphones to new heights and even in earbuds I can now hear subtleties that I didn't before. Good power and coupled with my Fiio Q1 it can drive anything from high impedance phones to greatly improving the sound from my stereo. I record everything in FLAC now and with a 128 GB card I can hold my entire library and then some. Can't imagine needing anything beyond this X1 to really enjoy good music!

FiiO X-1 Gold

Excellent sound. The X-1 can almost replace your CD collection if it fits on a 128GB card. I am 99% satisfied with the X-1. I enjoy excellent sound, and if I didn't know any better, I would have been perfectly satisfied, but I discovered the FiiO X-5 (original 1st issue). I use the X-1 hooked to Line Out through a real stereo. The 128GB card holds plenty of music to rock-out with, and that's exactly what I use it for. I run the units off of A/C so I can't attest to the battery performance, but, all tolled, these are excellent pieces of electronics, well built, user friendly (I know there are a lot of complaints about the UI (user interface) but I have it figured out and it does what I want. I like the user interface. I highly recommend the FiiO X-1. The FiiO X-5 (1st Issue) is my baby, though! I use WMA lossless.

Great looking and sounding

The first thing I noticed with these is that they are gorgeous. Obviously they are intended for the iPhone (et al), but they actually compliment the look and feel of an Apple product very very well. Vanity aside, the sound output is outstanding - keeping in mind the price. They are by no means "loud", proven by the fact that I need to turn up my Macbook all the way - with the convenient inline remote - to match the output of other earbuds I've had. This was uprising, considering the 16ohm impedance, but I don't mind it all as long as the output is clear and clean; it is. I do have two gripes with them, however. 1) They do feel a bit heavy to the ears. The first few days with them, it felt like they were ready to fall off, albeit never happening. 2) The 3.5mm jack sticks out about an inch of whatever you hook it up to - I will say that it makes it a hell of a lot easier to remove it from whatever.
Overall, great product!
