Sonos or Mac as Source?


Dug around a bit but couldn't really find a definitive answer so here goes...

Gear: Peachtree Audio Grand Integrated (non-X1 version) with sources consisting of Sonos ZP80, Mac Mini and Lexicon RT-10 player, driving Vandersteen 2C speakers.

Almost all of my listening is playing AIFF files through my Sonos, originating from a 15TB server on my network. I also do a fair amount of listening of Pandora and SiriusXM though the Sonos as well. So far, I've been running the Sonos into the GI via coax digital and I've dabbled very little in the Mac, running it via USB with Audirvana.

In wanting to improve further on the sound, I have a few options, but don't want to invest in all of them to find out which is best! So anyone with experience in a similar situation would provide some great assistance to me if they could comment.

Options:
1. Upgrade the GI to an X1 version and use the Mac Mini with Audirvana. COST = $250
2. Buy the standalone X1 USB-Coax/Optical converter from Peachtree and still use the Mac as a source. COST = $150
3. Buy the Wyred 4 Sound Remedy reclocker and install between the GI and the Sonos ZP90, using the Sonos as the source. Cost = $400

The simplicity and stability of the Sonos system/interface is very appealing. However, if the Remedy reclocker with Sonos doesn't approach the quality of sound obtained by using a Mac Mini as the source, I'd be willing to forgo a little convenience that the Sonos affords. Additionally, staying with Sonos as a source affords me the ability to improve Pandora, Sirius, etc as well...assuming the Remedy would yield and sonic benefits on those source programs like it would on AIFF files.

Going in circles right now with what's the right next step, so any help is sincerely appreciated.

I briefly tried using my Macbook to control the headless Mini but the lag time on actions was kind of crummy. I have yet to try one of the remote apps for an iPad. Sonos interface just works so damn well!! Makes it hard to want to mess with something else. One of these weekends I'm going to do a side-by-side between the Mini and Sonos streaming from my server. Probably won't be for a couple of more weekends though. I did download Audirvana though so I have that ready to go.
Jkscherk. You need to get a monitor dummy plug from OWC as it will speed up screen sharing. Works great.
Agree with Skinzy on the plug. You really can't use the Mini via Remote or Screen Sharing without having an HDMI cheater plug installed on the Mini.

I use a Gefen HDMI Detective. Cleaned the lag up perfectly.
Thanks for the tip on the plug. I had heard that was a solution for screen sharing lag. I didn't know it would be needed if you were using a remote app as well.

My core question remains however..will the Mini+Audirvana combo be any better than the Sonos with the Remedy Reclocker or clocker mode from Wyred??

I did that last summer and compared my macmini(JRiver vs my sonos and it was clear to me that the mini sounded fuller.Both went through the same dac and electronics,same songs and same volume level.Also files were on external Lacie drive on the macmini,and NAS Western Digital My Book Live for Sonos.
I admit the Sonos has an excellent interface though,and the CR-200 controller is so easy and convenient to use.But the JRiver music player is no slouch either.I use a wireless apple keyboard and mouse for now on my macmini,viewing the playlists through a 23 inch display.
