Hello HPDJ,
W/O question,unless you want to spend obnoxious amounts of money, the combination of JPlay riding on J.River Media Center will turn your computer into the world's best transport. PERIOD !!!
http://www.jriver.com/Download this program. It's the best bargain in computer programs there is. Fifty bucks and you won't believe the transformation it will make in the sound quality of your music files. Plus the photo and movie capabilities make it a no brainer. You can download and use for free for thirty days the full unrestricted, fully functioning program for your evaluation. I'll buy you a drink if you don't decide to keep it.
You will think you've reached audio nirvana when you get this running optimally, but the addition of J Play into the mix will completely blow your mind.
http://jplay.eu/ While the J.River playback engine is very good, it can't compete w/ JPlay. Please note, JPlay has no library capabilities, you need J. River for that. I know it sounds confusing, but its not. I will be happy to help you in any way I can. I've played w/ both programs a lot.
Disclaimer: I have no interests of any kind w/ either program, other than to state that after evaluating both, I GLADLY parted w/ my hard earned cash to purchase them. The JPlay trial version is not full featured in that the sound punches out for about 10-15 seconds every couple of minutes. There is no loss of sound quality or other features, so you will be able to hear any improvements it brings to the table. I predict that you will be shocked to learn that bits ain't bits, even though mainstream audio will tell you otherwise.
Just so you can get an idea of how good this is, I do not ( yet, though I will ), use a separate DAC. I use an HP notebook w/ Windows 7 and Beats Audio. HP supposedly went to great lengths to maximize the sound quality of the internal soundcard in their Beats Audio equipped computers, and it appears they succeeded. If you have a good soundcard in your computer, you should be able to get very close to SOTA performance. I know you all think I'm crazy, but try this on for size.
I feed the output of my computer's headphone jacks directly into my Stax SR007TII headphone amp, w/ Omega I cans ( I've got a set of Omega II cans, but I prefer the original version I ). this is a VERY revealing setup, and I can state w/ complete honesty that I can get lost in the music in a way that I never could using any CD player, and the best I've heard is the Burmeister CD/linestage combo , which is not too shabby.
Next, I took my computer to my buddies house ( he owns the Burmeister ), and fed the output into his system, which is the most revealing and musical ( for headphones ) system on the planet.
Macbook Pro/Amarra, feeding a WeissDac 202, into a fully tricked out Woo Audio WES ans A Stax SR009 earspeaker. Was his Mac/Amarra/ wesiiDac system better than my notebook and internal Dac w/ J.River/JPlay ?
Yes, it was. But the difference was miniscule. My computer source was so close to his I'll quote him " If I had heard this ( mine ) prior to putting my system together, I never would have felt a need to upgrade. "
Bottom line. If you've got a good soundcard in your computer, and at least Windows 7, get started. You've got nothing to lose. Again, I will help you in any way I can.
Cheers, Crazy Bill
