There has been a lot of conversation here about this upsampling audio player for Windows, Linux and OS X (Apple), and since I’ve been a very happy user for a while now, I thought I’d start a dedicated thread for it. HQPlayer is the work of Jussi Laako and in my opinion, might just be the best player software available from a purely sonic perspective – it really is something special in this regard. From a usability, convenience and pretty GUI perspective however, some feel it leaves a lot to be desired. There certainly are some negatives which might quickly rule it out for many (and it’s not free) but if musical playback performance is your number-1 priority, it may be worth working through the ‘challenges’ and hopefully, this thread can help in those areas. There is a free trial available for this (draw your own conclusions!) but I’d suggest digging a little into what is needed from a system and setup perspective to get it working first – it’s only a 1 month trial and it’s easy to get frustrated and give up on it before you hear what it can do. I mention this as it happened to me; teething problems had me shelving it but a second try with more perseverance has me enjoying digital like I never thought possible and I believe that is mostly down to HQplayer and in my case, what it does with a good DSD capable DAC. I’m going to ramble on about the DSD side of this player but I should note that most of my digital listening is actually PCM source (all converted to DSD128 on-the-fly) and this player does have extensive PCM upscaling capabilities too – it’s just not something I use so I have little experience with it. And please; if you have a problem with this approach, feel it doesn’t matter, it’s all 1s and 0s, nothing matters beyond 16/44.1, etc. great, start another thread and leave this one to those who are interested.
