Looking for some advice from the experts on this forum!\n\n<sorry for the long post, but wanted to give all my info in one shot>\n\nI am setting up a Hi Fi system (setup given above), and I would like to play my local MP3 and FLAC files on the new Marantz. I want to play them in the highest quality possible (Marantz supports 24\/192) ie. retain whatever resolution either the MP3 or FLAC file has.\n\nMy soon-to-be setup:\n--------------------\nHT configuration 7.1.4; Stereo using 'Direct' mode\nSpeakers - GoldenEar - Triton Two (LR), SuperCenter XL (Center), Triton Seven (Surr), SuperSub XL and Klipsch In-Ceiling\nAV Proc - Marantz AV7703\nAmps - Monolith 7x (for 7.x) and Rotel (for .4)\nCD Transport - Marantz CC4003\nAudio Streaming services - Tidal HiFi\n\nCurrently I have:\n-----------------\nNAS - QNAP TS-251\nLocal 24bit\/192Khz Hi-Res and 320kbps MP3 files stored on a QNAP NAS TS-251\nMedia server - MediaMonkey installed on a Virtual PC running 24x7 on a NAS\nMediaMonkey app on Android plays songs on my AVR via Bluetooth AND stores files on my phone for offline playing\n\n\nMy criteria:\n------------\n1. I have 1000s of music files, and have painstakingly edited metadata, created many dynamic playlists etc. So I really want a solution that can do all these jobs centrally (currently I have MediaMonkey) regardless of how the songs are 'consumed' by different devices.\n2. I'd like to store all my music files in only one location and have ability to access them through one type of app (e.g. HEOS, JRiver etc) on ALL my devices - AVRs, iPhone, Android, Tablet, Windows Desktop etc.\n3. I've tried DLNA on my old receiver, but felt the UI was not intuitive and less fun to navigate. So I need the song browsing and playing experience to be rich (like any native smartphone app like Spotify)\n4. Having ability to take my files on my phone for offline use would be a plus (and thats why #2 i.e. using the same app for offline use, would be great)\n5. I can spend additional ~ $1000 or so, not more than that\n\nWhat I have noted so far (but unsure what's best route to take):\n--------------------------------------------\n1. Use Marantz HEOS app for streaming services AND my files on the NAS (i.e. use NAS as DLNA server using MinimServer or equivalent). Q - Will it retain the Hi-Res quality? Will it show me files' metadata, album art etc?\n2. Continue using Media server like JRiver\/ MediaMonkey\/ Audrivana on a dedicated Mini PC. Use the software's app to 'push' media to Marantz. Q- will it play it with Hi-Res quality?\n3. Buy a network streamer e.g. Cambridge Audio CXN V2. Use its UI (or its own app) to browse through songs on NAS or JRiver. Q- this seems similar to #1, so do I really need this duplicate setup? I'll be happy with Marantz's DAC.\n4. Buy a separate device with local Media storage e.g. Bluesound VAULT 2i. Bring all my files to this device and rip new CDs directly on this device. Q- Will it allow me to enjoy music in other rooms or stereo systems?\n5. Don't know much about how USB option on Marantz works. Other than inserting a USB drive with bunch of files, how else can that medium be used for playing local files on it?\n6. Anything that I haven't thought of? Maybe Roon???\n\nNow, in short, my Question is this:\n\nWhat solution (combination of devices\/ software) will give me Hi-Res audio quality & most flexibility given my criteria above?
