just starting - mac vs. windows computer source?


Hello all. I don't know much about the specifics of a computer based audio source, except what I have learned looking thorough the archives. I am still hoping you guys can help me with suggestions that are specific to my situation and considering the current and potential future advantages of using either a windows or mac based system as a music source.

I have a fairly dialed in audio system (see my virtual system under mitch2) but want to now include a computer based source (I know, I am quite late to the party). I currently use a new(ish) windows based laptop for home computing, have external hard drives, and also have a windows based laptop for work. My only mac exposure is the company i-phones we recently adopted, my wife's ipad, and looking at my daughter's macbook pro. I have hundreds of CD's and a very high quality hi-rez player, but none of my music is yet digitized.

I want to add a high quality, great sounding computer based audio source that is at a similar sound quality level as my current player (or better), and I have heard using the ipad as a control and visual display, and the mac mini as a server, is a good way to go. I like the idea of having the mac mini near my gear, so shorter cables to the dac, and I like the idea of controlling everything wirelessly from the ipad, but this means I will need to buy more stuff and will not be able to use my windows based laptop for that function. I am okay with that as long as the ipad/mac mini is really a superior solution.

I have four questions regarding my decision to adopt a mac based or windows based music solution. At this point, I want to focus only on which computing system is best for me and handle dacs, cables, etc. later.
My questions;
1. is the overall consensus that the mac based system is better for hi-rez music playback, considering my goals are very high quality playback, wide bandwidth, low noise, and ease of operation,
2. is there a windows based system that could sound as good and be operated similarly to the ipad/mac mini option, perhaps using my windows based laptop as a control,
3. if I go the mac route, is there any advantage to purchasing a macbook pro over the ipad to control things, assuming I still plan on using the mac mini as the server, and
4. what other questions should I be asking that I haven't asked?

Thanks for any solutions or suggestions you guys care to provide.

Lewinskih01, this research has been a learning experience and the choice is difficult because each system had its advantages and it seems they are equally good sonically, when set-up properly. I don't mind paying a bit more to get the level of server I want up front, but I only want to go through the decision once.

For reasons of compatibility, I would prefer to stay with an all Windows based system but when I compare the server options it seems that a similar level CAPS server is significantly more expensive than even a very good Mac mini and, in addition, the CAPS gear seems to be tweakier with the variety of connections, power, etc. No question, the Zuma with Red Wine PS looks very good but I would be looking at about $3,400 for that combination while I can get, directly from Mac, a brand new mini i7 2.6 GHz quad core with 256GB SSD and 8GB memory for a flat $1,300, which is $900 less than the CAPS Zuma alone, without the Red Wine PS. The Mac is well-supported, can be configured at the factory exactly as I need, and seems to have a wider following.

Regarding power upgrades to the Mac, I have learned power supply improvements yield huge dividends in most audio gear, and everything in my system has an outstanding power supply. Therefore, it does go against my grain to consider that I wouldn't upgrade the stock switch mode supply and fan in the Mac. However, you are correct, the threads about Core Audio and Mojo indicate there are issues. I also don't like the idea of voiding the Mac warranty by changing the power supply. Therefore, I think it may be best to stay away from PS upgrade options, especially since most users apparently find the stock Mac mini PS works just fine, without those upgrades.

Unless I learn something different, as much as I would like to consider a windows server, the Mac mini option seems better for me except for compatibility and power supply issues. If the power supply were such a big deal, I doubt so many with high end systems would use the mini as their digital audio server. I haven't made a final decision but I am leaning toward the Mac.
I love Macs, and use them for everything but my music server. There are different schools on what or why computers, player programs and file types sound different. Although the general consensus is that noise is the primary issue, there appears to be different views as to what noise to deal with- into the computer, out of the computer or within the computer.

You have mentioned CAPS, and that is one option- a low power motherboard that clips along at a steady speed with isolated USB. Another option, and the one I have chosen over time, is the high power pre-processing that then nearly shuts the computer down as the files play using XXHighend as the player program.

FWIW, I wish I could have stayed with Macs, but XXHighend on w7 sounds the best hands down. It takes some work, but it is worth the efforts. I have used every player on Mac and a well respected Linux based appliance server (Auraliti- similar to a CAPS).
I'd have to disagree with computer audiophile on processing power, more is better, reducing potential for jitter, cycle steal interference. The problem is that faster clocked motherboards and CPU's become electrically "noisier" and most builders don't have electrical noise reduction as a priority in a consumer product.

Lewinskih01 has a very good point about going the route of USB to SPDIF converter. It provides you the opportunity to isolate your audio system from the computer system. After reading through this posting here about true linear power supplies and the PC I decided to go the route of isolation. If you use your laptop as a starting point for your source your will have the basic idea of a Battery powered CAPS. If you like what you hear with that could build your own dedicated fanless PC or go the MAC route.

By the way I decided to use a PC as I plan to use it as a movie server also. I use a battery powered SPDIF converter that draws its power from a USB port.

P.S. Glad to see you finally posted your SMc Audio TLC Signature, very nice. As promised I didn't say anything till you posted it. Have mine scheduled for go back to Steve later this year when he has time.

If your interested in hearing more you have my e-mail and I will provide more detail reading info for you.
