Sharing iTunes files between PC & Mac?


I use iTunes on both a PC (in my home office), and Mac (in my listening room, with Mac laptop connected to my DAC). Currently I have my music collection ripped to Apple Lossless and saved on an external hard drive connected by USB to my PC. I have created lots of playlists using my PC version of iTunes.

Currently, when I want to hear these files in my listening room, I open iTunes in my PC, then open iTunes on my Mac laptop in my listening room and connect wirelessly to my PC's itunes library through the iTunes "Shared" mode.

This seems to work fine but I have 3 questions:

1) Am I getting the same quality when listening to my mac/stereo when accessing my PC's shared iTunes library as I would get if I had those same music files wired directly to my Mac on an external hard drive? And would that be the same quality as accessing the hard drive from both PC and Mac on a wireless network?

2) Can I unplug a hard drive of Apple Lossless files from a PC and plug them into a Mac to use with Mac iTunes, and go back and forth without any problems?

3) Can I share iTunes metadata, such as playlists, ratings, etc., by creating them on iTunes for PC, saving them to an external hard drive, and accessing those files from the hard drive to my Mac? In other words will Mac iTunes read the iTunes Music Library (metadata) folder created using a PC?

In the original post you mention using iTunes on a PC and a MAC. You described the improvement directly attaching storage to the Mac vs wireless, but can you compare the sound quality of the PC vs the Mac?

Everything I've read hear says that iTunes on a PC results in very poor quality. Is the PC connected to a serious system like the Mac, or is it just backdround music?

I'm asking because I'm tryin to set up my older PC as a server and I've been avoiding iTunes in favor of JRiver software because of the reported problems with PC/iTunes.

Thanks
Need to set the output in playback under setting in itunes on pc, and set to windows audio session.

on mac need to set ouput quality under midi controls. Ie set to 24/192 or 16/44.1 etc. 

most of the differences in quality I have found with people’s settings are because of those settings. People don’t know what they are doing and therefore think buying new boxes which do the thinkimg for them make the stereo aound better.

you also need to check the hardware settings of sound output to dac if on pc in sound in system settings. 
Macs are intel based, basically pc’s now. Also most 3.5mm headphone jacks on mavs 2/3 years old are also mini toslink optical outs.
