PGGB is great, but does come with some baggage: As already mentioned, you do need at least 32GB RAM, with 64GB or higher preferred, to process your music. Of course, this can be, and ideally should be, an unrelated machine to your music server/player. The resulting files are very large. With 32/16FS files, the storage needed is about 15-20GB per album Network streaming is not amenable to this approach, so for me as a DAVE user, I still rely on HQP sinc-L/LNS15 fed either from Roon or TAS (Taiko Audio Server). The latter's sound quality runs circles around Roon, but in discovery mode for new music, I can't deny the elegance of the Roon user experience. For local playback, a network store like NAS isn't really a good option, as even with a 1Gbps home network, the load time for a 4GB file can be significant at a max read/write rate of 100-110 MB/s. Now to your question. My entire local library of ~1600 albums at native sample rate occupies about 1.5TB. After PGGB conversion, this would need ~32TB. While Emile assures me that upgrading the NVMe SSDs in my Extreme will not negatively impact SQ, I am reluctant to do it due to the cost. I currently have 8TB. So I am approaching this as a sort-of jukebox, in the following way: Of the 1600 albums in my local storage, I only truly care about say half of it, or 800-1000 albums, so only these get the PGGB treatment preemptively. To store this content, about 16-20TB, I will use my NAS which already has adequate capacity. This will be my upsampled repository or warehouse. At any given point in time, I'll keep a subset of this repository on my music server, say 300 albums, or 6TB. This will be my jukebox. From time to time, I will rotate albums in and out, moving them to/from NAS (warehouse) to the server (jukebox). I've toyed with the idea of using external USB storage, but am concerned about the SQ. Further, because of the size of these files, it really helps to have disk read speeds of 100s or even 1000s of MB/s, which NVMe drives do provide. A well implemented USB 3.2 SSD, with appropriately clean power with external PSUs might prove adequate, but this remains TBD in my setup. Rajiv with your background you should be able to setup a triple redundant CDN in your basement with a 40 Gbe fiber link to your listening room. Piece of cake. :) austinpop and The Computer Audiophile 2 Link to comment
