Can I Improve Sound--Macbook Pro as Music Server?


My system:

NAD M2 (amp/dac)
Audiphilleo2 spdif to usb converter
Macbook Pro (2012) /Furutech Formula 2 USB cable
Itunes- Tried Puremusic demo and thought it was actually less impressive than Itunes
Speakers: Mirage OMD 28

Files are all on the Macbook Pro- don't have an outboard drive yet

Recently switched to ripping in AIFF after starting off with AAC

My system sound lacks a little in weight / clarity/ resolution

What can I do do beef up / clear up the sound with my Macbook Pro?

What about the optional power supply for Audiophilleo2?

Thanks

Have you tried Audirvana Plus? It sounds different from PureMusic. You may like it better. It has a 15-day trial as well.
No, I haven't tried Audivarna. I'll try it.
Put your music files on a separate drive and use a firewire connection. (It's important to use a different bus connection than what your music drive uses). Max out you memory, 4Gb at a minimum. Only use non-data compressed files. Try Pure Music again and set it up for memory play with factor of 2 upsampling.
Onhwy61, thanks for the post/ I should have mentioned that I'm still trying to sort out CA and what you just said in your post is mostly a foreign language to me.
Optimize your Mac OS for music server

Reinstall the OS on a clean new partition preferably on an SSD

(this may not be applicable if you run the MBP as a multi purpose machine)
- disable spotlight
- disable IR
- disable Dashboard
- disable Spaces
- disable Energy Saving
- disable BT (and WiFi if you aren't using it)
- disable Time Machine

Use Audirvana Plus
- use A+'s System Optimizer
- enable Direct and Integer mode in A+ (should be supported by the USB-SPDIF device

If you are using a USB-SPDIF device like the Audiophileo, store the music on Network Server with a wired connection or use a Firewire/Thunderbolt external HDD (not USB).
Thanks Doggiehowser,

I know SSD is Solid State Drive. What's a clean new partition?

If you are using a USB-SPDIF device like the Audiophileo, store the music on Network Server with a wired connection or use a Firewire/Thunderbolt external HDD (not USB).

I use the Audiophilleo2. What's a Network Server? Which ones are good? I think I've seen a Thunderbolt (do you mean, don't get a Thunderbolt with USB capability?

Are you saying ethernet? I use WiFi now but have considered running an ehthernet cable into the room where the Macbook Pro is located. You're saying to run ethernet to the Network Server rather than the Macbook?

Obviously I don't know the meaning of some of the jargon.
New partition means a fresh installation, not an upgrade of an existing installation. I use "partition" as opposed to a disk because you may wish to create more than one partition (eg 1 for Bootcamp to run Windows and another to run Mac OS X for regular apps, ie not for music).

A network server (or network attached storage server aka NAS) is basically a dedicated computer that you can store far away from your music playback computer. It contains hard disks that are noisy so if you really like, you can keep them in a separate room away from your hifi equipment and use a wired network cable (Gbit recommended esp for hires music) to allow the music playback computer to gain access to the music files. The NAS also allows you to run arrays of drives for redundancy etc

A Thunderbolt port is a new interface available on newer Macs circa 2011 and up. So on most new Macs, you will have the option of USB or Thunderbolt (or USB, Thunderbolt or Firewire). Never use the same interface for the USB-SPDIF device (in this case yr Audiophileo) and the music storage, should you choose to use a local drive (vs a network storage system).
Simplest thing for you will be to get the "audio Optimization Guide" from iTunes iBooks for your Mac OS. Search on iTunes iBooks. This has step-by-step details on how to kill unnecessary applications.

You can swap out the hard drive for a SSD by using instructions from otherworldcomputing.com

Thank you Audioengr. I doubt seriously I'll be opening up the Macbook Pro however. Not interested in taking any chances.
The MBP unibody is actually quite easy to open up. Apple even puts instructions online (to upgrade memory)

The new retina MBP on the other hand I'd not recommend opening.
