I just upgraded from Pure Music 2.04 to 3.01 on my late 2009 MacMini running Snow Leopard and noticed a big improvement in sound quality. What I am hearing is an overall increase in clarity, separation of instruments and tonal richness, across the frequency spectrum. I listened to a number of reference tracks on 2.04 before installing 3.01 and then listened again. The difference was very easy to hear. For example, in the huge tutti at the opening of Scheherazade, the sounds always seem sort of muddled together under the old version, but they were much more distinct under the new version. It seemed as though I could hear more overtones on sustained piano notes and violin tones, etc.

PM 3.0 and the new Mac OSX. I could not do a realistic A/B comparison since the process took quite a while. It works well and sounds good.
Recorder, I am using an early model 2009 MacMini with Yosemite as the OS and have installed the maximum amount of supported RAM which is 4GB. Since Pure Music recommends 8GB of RAM I have not given it a try. Have you tried it with 4GB of RAM and if so, how does it perform?

The Mac Tracker iPhone app states that although Apple officially supports only 4 GB of RAM on the 2009 MacMinis, they run fine on 8GB of RAM, as Abe said. I had OWC install the extra RAM and a SSD on my MacMini and it runs fine on Snow Leopard.
i have two partitions on my SSD, so that I can run in either Snow Leopard or Lion and it sounds better on Snow Leopard, so I have not tried installing later operating systems. i feel more comfortable running an OS that is actually optimized for the hardware, rather than much later OSes that are optimized for more advanced hardware. I believe that is the counsel that I got from Channel D some time ago and I have stuck with it. I only use it as a music server.

If your Mini is in fact a 2009 then it has a Model ID of 3,1 which will (unofficially) support 8GB of RAM. You cannot upgrade it through Apple but it is known to work fine with 8GB. You can buy (2 x 4GB modules = 8GB) from OWC Mac Sales.
You might need to update your EFI Firmware first. It is often updated automatically with OS software updates, but still worth a check to see what you have. If it is version 1.2 or newer, you're set.

Do you know how to open the Mini? I've used a putty knife or two. There should be an install video on the OWC Mac Sales website, or seek out an independent Mac shop.
I chickened out. I recently had a professional increase the RAM from 2 to 4GB and replace the original 128GB HD with a 250GB SSD. I obviously made a mistake by not attempting to upgrade the RAM to 8GB; but in my defense, Apple Support documentation states that max RAM is 4GB and when I looked on the Apple-sponsored forums this was repeated and stories about catastrophic failures prevailed with the attempts to upgrade to 8GB. I am incompetent to install the RAM myself so I will have to live with 4GB and stick with Audirvana in iTunes integrated mode which works just fine. And thanks again Abe for recommending this mode.

Never heard of such a thing, unless the memory was not the right type, the EFI Firmware was old, the memory was installed incorrectly, or the system was somehow fat fingered and botched up during the installation process.
I've used memory from OWC Mac Sales in the past because they thoroughly test to ensure that the memory they sell is fully compatible with the Mac model being upgraded. They charge a few bucks more but it's worth it IMHO.
I have Macs with memory that I have upgraded beyond what Apple sells and they work perfectly fine. If your Mini was under warranty I can understand the hesitation but it's a 2009 model.
If you feel squeamish about doing it yourself, you might ask your tech about it and have him do it. The additional RAM will open up new possibilities especially with players like Pure Music, Audirvana Plus, Amarra, HQPlayer, and others. The additional memory also allows you to allocate more to the "memory play" feature in Audirvana Plus and others.
was for CDs somehow played through AV+.
Do you recommend it for File Playback?
I've got 16 GB on IMac/Yosemite.
Do you recommend it for File Playback? I've got 16 GB on IMac/Yosemite.Sure! Give it a try since you have lots of memory to spare. You may or may not hear a benefit. It loads tracks into RAM before playback which can theoretically help especially if your music resides on spinning disk.
I have my memory play allocated at 8GB of RAM, which is plenty.

Please to direct me to it!
AV+
With AV+ launched, go toward the upper Left of your screen and click on Audirvana Plus, then click on Preferences.In the Preferences pane, click on the Audio System button.
Move the slider toward the bottom of the window to adjust the amount of
memory to allocate for "memory play". Mine is set to 8,192 MB which is
8 GB. Once you've made the change, exit out of AV+ completely then
relaunch it to ensure that the change took effect.

8 GB it is!
Just upgraded to Pure Music 3.01 and OSX El Capitan. Everything seems to be working. Will listen tomorrow.
