High Resolution Music Server Software for Apple Macintosh Computers2011 Absolute Sound Golden Ear Award
2011 Positive Feedback Brutus Award
2010 Stereophile Computer Audio Product of the Year Runner-up (after Channel D Pure Vinyl™)
Simply and automatically docks with iTunes
"The sound is excellent, and the memory play with gapless files is doing well... Thanks for all your work on this... great product." "I love the product, it destroys the competition and I'm trying to figure out the best way to diplomatically express that opinion [on an audiophile forum] without igniting a flame war." "Historically I'm a pure vinyl user but I always wanted only the player part of this software without the overhead..." "It has an outstanding low end, the imaging is excellent." "Congrats on having a winner ... substantially improved the performance of my computer audio server setup compared to iTunes." "pure bliss" "I continure to be very very impressed with Pure Music and was further impressed with the telephone tech support. I don't recall who I spoke with, but he was terrific and the problem was quickly resolved. The ability to access my computer was great and not only was a more efficient way to figure out the problem, but I could also see & learn how the problem was fixed and preferences was navigated. Your service should be a model for tech support." "Never better sound... amazing clarity and soundstage." "I have just purchased your Pure Music player and was delighted with the quality of reproduction vs. iTunes. Tonight downloaded the update that allows you to upsample - wow - best digital replay I have ever heard from my system. Keep up the good work - what's next?" "I gave your Pure Music program a try and I have to say I'm impressed - playback sounded noticeably better using Pure Music than with iTunes alone, for files from 44.1 all the way to 192 kHz sample rates. Interestingly, setting my FireWire/S/PDIF converter to 24/192 and allowing Pure Music to up-sample files rather than having the DAC do the up-sampling also bumped the sonic performance up another notch." "Pure Music is by far superior to the famous player A... High range and dimensional image are nearly perfect." "Your software is a great achievement for computer-based music users. It sounds definitively very nicely, with a full and rich medium, detailed high and clean bass... the dimensional image is wonderful, wide, deep and opened. Globally, it's well balanced, very musical!" "I'm currently testing Pure Music 1.2 and my first listening conclusions could lead me to replace [a competing product] I currently use. [That product] is already a great improvement over iTunes, but I found that Pure Music is going quite a step further: more tri-dimensional image, much more definition, presence and "matire" (sorry, I don't know how to translate the exact word in audiophile language) on voices and instruments." "I hope you have a lot of success with this new player. It might be exactly what the 'pure digital' guys need (at least the ones who can rise above the snobbish attitude that it has to be expensive to be good)." "I have been using the Pure Music player for over a month and prefer it to [the much more expensive competing product]." "[Pure Music] 1.2 is great! Thank you for your continuous support, it's been outstanding." "Pure Music sounds splendid - you must be very pleased with it." "I love the product." "The sonics of Pure Music... are a revelation." "Today, I uploaded Pure Music 1.11 demo and WOW! That sounds freaking fantastic." "the program is really sweet." "I've been a very happy user after moving from [a competitor]." "Very impressed with your product." "...congratulations on such a wonderful piece of work."
