you can tell i've got too much time on my hands these days!
A little experiment today, discovering what files my Marantz SACD will play through the front USB port via a 64GB flash drive. It turns out that it will play PCM files so i did a back to back test, and they are noticeably better in quality to the 320kbps MP3 files i have loaded.
question is, how many albums can i fit on a 64GB in LPCM ?
i've got over 500 albums on there at the moment, so i'm considering ripping a bunch again, as LPCM and swapping them out.
may as well while i'm sat here relaxing, enjoying the music.

Was never interested in ripping my CDs until it became feasible to do it losslessly.
You hear stories of people that ripped their collection to mp3, then got rid of the CDs!

I haven't done the sums for you but I have music recorded in a number of formats and below list an average for albums recorded in these formats.

2.8KHz DSF album. 2.08Gb
96/24 WAV album. 1.35 Gb
Ordinary WAV album 435Mb

I’ve done mine at least 4 times. 500+ CDs at a time.
Had an iPod, so ripped to iTunes.
Laptop broke, so ripped again to new one.
Ripped twice again since! For mp3 for the car and for SACD player.
Laptop broke again, removed all files, and now find myself doing them again to WAV.

I’m probably being dim, but where do PCM files originate from? Reminds me of early Denon digital recordings, if my memory serves, but not sure where you’d source them today.

Yep, linear PCM or WAV is simply an uncompressed format much like FLAC that you can rip CD s to.
Most of my CD s are ripped to FLAC as soon as I get them and stored on USB solid state hard drive for home use and 128Gb micro SD cards for my DAP for when I am away at work.

500 albums at 700mb (CD max storage size) is 350gb get yourself a 1tb stick £22 from amazon and probably cheaper off my memory, it will fit the lot, bear in mind to back up somewhere memory sticks can and will fail.
They are not archival.

Probably fake like all cheap USB sticks that promise the earth for virtually no money, Stick with a brand name to make sure you get what it says on the tin.

Save all your files as FLAC (Virtually everything supports them these days) as they are lossless and will be half the size of WAV, in addition they can store all the metadata which WAV can’t.

the reason i have used WAV is because that is what the Marantz will play through the front USB. i think thats about the best sound quality i can get from that.
the connection on the rear will play other stuff, but needs a laptop connecting, which i'm not bothered about doing (not yet anyway)

You have a SACD player, and use a 64Gb flash drive? You’re a real tightwad aren’t you? Pucker up and get a Sandisk ExtremePro 256gb stick that I got two years ago - it’s an SSD on a stick afaik. It will be an eyesore, but you’ll get over it.

Also, don’t use WAV, get EAC for free and rip in FLAC. And when you configure for first use choose the ‘quality’ option over ‘speed’. Ripping will be a bit slower but much better - trust me.

Good plan. Ripping to FLAC will save space over WAV as it is compressed but the difference in sound quality is probably not discernable.

here's one that won't look like an eye sore might be a bit slower but it will get the job done

FLAC and ALAC (Apple Lossless) are lossless compression formats. When you decompress the files they will have exactly the same properties as the original PCM (WAV or AIFF). You can even transcode from FLAC to ALAC and back without any quality loss.

Like I have mentioned before. It has to be WAV as that’s the highest quality file the Marantz will play via the front usb.
All the high res type of files will only play through the rear usb via a computer,

Bit like my Oppo, I have to connect my solid state drive to the USB on rear for DSD and hi-res files.
Bigfish’s Marantz has only one USB-A port for usb sticks - the one in front. And it doesn’t accept FLAC. There is only a USB-B port at the back for PC duty, and even with an adapter it won’t accept sticks.

Big fish , it’s good to know I’m not the only weirdo loading up CDs on USB sticks instead of using NAS drives etc. And I’ll never bother with connecting a PC. It’s horrific for me.:p

Hopefully by the time I’m on my days off I should have received a few more CDs to rip.
I got the Mrs to buy 2 discs I’d been after for ages, they were listed on eBay so bought them.
Then, about 10 mins later, I noticed lots of the same 2 CDs for sale, and all in Russia.
This seemed a bit too coincidental, so I’m expecting them to be counterfeit.
Buyers remorse 🙁

PCM is not necessarily relevant to just audio, but a technology for converting an analogue signal into a digital one. I’m a massive RC aircraft nut and PCM was used in receivers as a means of digital telephony. So an analogue signal from the transmitter to the receiver where it is changed to digital for all the digital channels and servos (aileron, rudder etc) . The tech is now different in RC with 2.4ghz DSM.
