I am using JRiver Media Centre 23 and I don't plan to purchase the upgrade to MC24. JRiver gives you free updates, however, when a new edition of JRiver is released you have to pay an upgrade fee. This is a significantly higher price tag than my JRiver software which will load on multiple PCs and sells for $59.98 US. JPLAY sells for 149 Euros which gives you permission to load it on 2 PCs. The founder of the company, Marcin Ostapowicz, explained that JPLAY FEMTO was not created to compete with products such as Foobar and JRiver but to provide an audiophile grade alternative. JPLAY is different from the other two in that it is designed to operate from a remote device such as a smart phone or tablet etc. The only others this reviewer has experience with are Foobar 2000 and JRiver Media Center. JPLAY is the newest edition to the very short list of products that can play the full range of high resolution music formats via a Windows based server. From this point on, JPLAY FEMTO will be referred to as JPLAY. To save you the trouble of looking it up UPnP means Universal Plug and Play, a standard for network enabled devices to discover and establish connection to each. It improves sound quality of local library and online lossless music services such as TIDAL & Qobuz (including hi-rez Qobuz Sublime plan). It supports virtually all audio formats and resolutions including DSD Native (RAW) up to fs256 & DSD DoP up to fs256. It consists of JPLAY femtoServer, ultra-light and ultra-optimized UPnP media server & JPLAY FEMTO UPnP Renderer. JPLAY FEMTO is a complete network music software player for the most demanding audiophile. What is JPLAY FEMTO? Here is the definition taken from the JPLAY online manual. Product name: JPLAY Network Music Player Software
