Summary: Sound is a subjective matter, but there are certain categories that set apart products from one another. If you listen to Logitech speakers or some other form of "computer speakers" you are missing out on true audiophile sound from your computer or other gear. The KEF speakers are a league ahead of the other powered computer speakers on sale here. That being said, they are very expensive.
Summary: I have tried many speakers in my home office for casual listening. My main system is an all tube affair with serious components so my office system has to be good to great for me to enjoy it while I am working. These KEF speakers do the trick with ease. The sound is dynamic and open without any hint of stress or strain. I use them directly connected to a Sonos ZP-80 and also via iTunes using Airplay.
Summary: Yes these speakers cost me a lot of cash! However, if you're a music lover...Don't hesitate to take the plunge. Out of the box you'll notice these speakers are top shelf! (no pun intended). The sound is high end period! They are easy to set up and Airplay is major plus.
Relevant missing features limit usability. Good in terms of audio.

Summary: Original review below. Revised to 3 stars after breaking in and extended listening due to its inadequate bass and low mid levels. The unit I have simply sounds quite thin even with setting for speaker stands which warms up the tone. I A/B it with the 'lowly' Audyssey Media speakers run out of a Dragonfly DAC and at low to medium low volumes, the much smaller and lower cost Audyssey is significantly more 'correct' in its warmth and bass extension.
Summary: First, let's just get it out of the way that the sound quality is drop dead gorgeous. You are going to get clear, distortion free sound all the way to maximum gain. The highs are exceptionally expressive and detailed. I have tried listening to a number of genres on these speakers and they are excellent in every case. In classical music, instruments such as violins sound incredible- each note sonorous and gently blending into the next. Pianos sound great.
Summary: There are lots of reasons to NOT buy the KEF X300A powered speakers. (Spoiler alert: buy them anyway.) - They're extremely expensive. There are other powered speakers that sound great and cost less. - There are only two input options: USB and 1/8" mini jack. No RCA, no XLR, no optical, no built-in wireless streaming. Cheaper speakers have some or all of these other input options. - The X300A's "feet" are permanently attached to the bottom.
Summary: pros; look good, sound good, solid construction, shipped to me so fast I couldn't believe it. cons; if it weren't for the input jack I would send kefs back same day I received them! internal dacs are cheap and sound pretty bad if your using a very well put together pc. their fine if your using a challenged pc or a laptop that its internal audio is average or low quality sound.
Summary: I struggled on spending this much for speakers for my computer but it was totally worth it. Amazing sound quality and imaging. It took a little research to figure out the midi settings on my mac to get them to match the sampling rate the DAC was expecting but once it was setup, perfect sound.
Great speakers! Mac users: beware of Audio settings!

Summary: I wasn't satisfied with the B&W MM1 anymore since I want to have a deeper soundstage and a clearer bass (not just the booming base, but a clear, well-defined bass). I actually got the first pair of MM1 but I gave to my dad. Don't get me wrong, this first MM1 is amazing and the soundstage is awesome, but then I had to buy a replacement pair. This time I'm not as impressed. Somehow the sound came out flat and uninteresting.
Summary: Purchased to use in an application where an amplifier would only complicate my situation. However, there are some limitations (I have 5 major issues with this setup): 1. uses 2 (seriously) heavy gauge cords. If you are installing in a bookcase, an open cabinet or have limited space to run wires....this thing has cords coming out it like crazy. (2 power cords, 1 USB connection, and possible multiple inputs).
