Apart from some minor slips, settings of the JRiver/JPlay combo were essentially intact and I was able to do a bit of finishing touch. Results are promising.

A visit to JLeung to see how his CAS is doing. He has a reasonably good sized sitting room which accommodates the giant Wilson speakers, the Clearaudio Statement as well as a load of deadly high-end electronics.

Back in the golden age of recording, there were more than 2 dozen of great masters. After half a century, these masters are either dead or their hearing acuity would no longer allow them to work at the console any more.  
 
Today, despite ground-breaking advances in digital recording technology, good recording engineers are few and far between. To the best of my knowledge, there are only two: Tony Falkner of RCA and Mike Hatch, a most sought after free lancer probably, since he has worked for EMI, Naxos and Decca respectively.  
 
Recording is truly an art form where high tech can help but does not necessarily make anyone a recording master. What's even worse, IMHO, the global decline of classical sales simply means inadequate fund is available to attract aspiring engineers.

Trouble is we can't pull the dead to record again in today's technology. We will never find out the best performers/recording engineer can do in today's state of the art environment. Some of the folks at Telarc, and Blue Coast were indeed the tail end or students of those great masters. Yet, did they not learn everything or the technology was inferior when their work didn't sound good. That we can't find out either ... Don't matter, I like, cake, coffee, cheese, ham, wine, mix w/ music, all good.

Having had the CAS running for almost a year, I guess I have gathered some guide lines by which I may approach this program source without getting myself lost in a world of fast moving computer advancements.  
 
1. Up-sampling is, more often than not, fouling an otherwise good recording. I come to this conclusion by listening to Playback Design as well as comparing CDs against hi-res files of the same recording from HD Tracks.  
 
2. The difference in good Vs bad recording far outweighs the importance of format used. In other words, the recording itself determines the make or break. Whether it is hi-res files, DSD or just red book CD do not seem to matter much.  
 
3. The major drawback of digital sound reproduction seems to lie largely on its lack of harmonic timbre and nuances. In this respect, the discreet use of buffer does make a difference quite beyond imagination. I do not know exactly why nor do I care about the reasons behind so long as we have music that touches the heart.  
 
4. Quite contrary to conventional wisdom hence, the quest for ever lower latency doesn't seem to pay good dividends. This has been very puzzling at first but as I gathered more and more evidence, I cannot but have to be convinced. Lower latency does not necessarily ensure better sound. The rule of thumb is to use your ear instead of your eye to determine the right setting.  
 
5. The ability to pool resources is unprecedented. It shouldn't take long before one could have more than a thousand albums which, when translated into analogue equivalent, would amount to some 2,000 LPs. Assuming you can spare time to listen to 3 albums per day, it would take more than a year to finish them only once!  
 
 
P.S.  
 
I hasten to add that I am just a newbie who tries to find his way through trial and error across this relatively new discipline. If you should find me terribly wrong in whichever way, please have me corrected and share with us your invaluable view.  
 
I suppose CAS is still at the stage of infancy and room for improvement must be plentiful.

Welborne, never been a SBT guy actually. I jumped from a CD player directly to CAS. My current digital audio consists of a PC in an Origen case. It's a AMD A6-3650 processor @ 2.6Ghz with 8GB RAM and Win7 Professional 64bit. I am running JRiver 19 and JPlay. Data goes through USB into a M2tech HiFace to Spdif and into a Atoll DAC100 which I tuned with Rike coupling caps. That's it.

Just two pages from his comprehensive blog.  
 
This device came originally with a firmware version that supports 24/96 only, but about a year ago someone wrote a new firmware called EDO that turns it into a 24/192 and 24/173.4 support device via spdif and usb (with asynchronous clocking). What is cool about it is that it also doubles as a very nice desktop clock with big characters and able to lock itself into any digital radio station in any parts if the world as soon as you hook it up to internet. Perfect toy for bedroom.

What in fact is SBT  
-------  
Oh I beg your pardon too. Was just too lazy in typing via iPhone. It is Squeezebox Touch. It is not new at all, and it has been discontinued by Logitech who makes it.  
 
I think other people here may know it better than me in explaining what it is. It is just another Linus based little computer that is designed purely for playing music and nothing else (no movie). It has got the media player program stored in firmware and runs it from there instead of like Jriver in spinning hdd. There are many media player devices like this on the market and SBT is just one of those. But a super cheap one. I was not paying much attention to it and was indeed put off by its cheap look (not unlike when I first saw the Sony DVP-P50 toy), but more than a few brothers around whom I respected so much too pointed me to this gadget and offer lots of help. Then I read an article by the Poland Lampizator guy who tested many cd transports over the years looking for the cream of crop and his search led him to discover that the Squeezebox has the best spdif output he ever encountered... So and so forth

Learning to set up SBT properly with NAS seems like being in a MS Network engineering course, haha. Only start picking up all these jargons like gigabit, Mbps, gigabit switch, Cat7, dynamic and fixed IP just 3 days ago. No wonder Logitech pulled the plug on the Touch as Logitech couldnt sell it mass enough to warrant the production. How many ladies would want to go through all these just to listen to GEM streaming from their [email protected]@

Why do you go NAS, does it sound any better?  
–-----------------  
 
Strictly speaking I am not using NAS (which I think refers to those who use NAS directly as both source and media player and directly output the digital signal from NAS unit to Dac via usb). In my case the NAS just serves as database management streaming files stored in 2TB hdd into my Linux based computer (5v power requirement) Squeezebox Touch which plays the incoming WAV or FLAC files into digital and output via s/pdif into my 1541a dac. Those who tried both intel i-cpu computer/jriver and this SBT solution urge me to go this path, for sonic reason, but I can't confirm as I don't have anything to compare with to verify. But i did make a comparison between SBT and play off CD on some common albums. I think I like what I hear from SBT.  
 
Oh if you wonder why I need NAS in my solution, I think it is the way theTouch needs to work as it is a network media streamer by birth. I would have wanted to just SSD harddisk---SB Touch but so far everything I read on forum says nay to this. I think it is the limitation of my rig..

Gentlemen, the current vogue in PR1 is breaking new ground once more, drifting widely apart across the audio spectrum: you have CAS perched on one side while mono reproduction on the other. No one takes serious interest in the boring stereo LP reproduction, nor the cutting edge (throat as well) developments of CD playback devices.

Dear Limage,  
 
Guess what, I already get started, but I took a side track from mainstream i3/5/7 to even more mainstream (arguably) Squeezebox Touch with EDO firmware. Got about 2TB load of wav files ripped from battery powered Plextor writer (of course not done by me). Most are red book format. I dont have a HD dac yet but will surely get one in near future. Actually, you inspired us so much, knowing your background and affinity with analogue system, not to mention your LP collection. Something must be good enough around to keep your fingers on the touch screen. :)

Music is to be enjoyed regardless of the format.  
 
I have a cave man CAS system for a while and I tend to listen at lower resolution as most higher resolution formats are just not musical. My LP listening has taken me further into the prehistoric age of MONO. While I am not yet spinning 78 rpm Shellacs, the MONO sound of some of the original records are just hard to beat in terms of itchy foot tapping. At the same token the convenience of CAS is also hard to beat without fiddling of the arm, record brushing, cartridge scraping ..... just don't get me talking about cartridge, arm combinations for certain type of music and LPs ! that's another long boring topic !  
 
Now hit that button !

Switching power supply and spinning hard disc notwithstanding, the sound can be amazingly commendable from the barest form of computer audio, to wit, one stock pc feeding one reasonably good DAC.  
 
After tweaking with the multitude of adjustments for a little more than a year, I no longer have to compare sonic results against CD players any more. The challenge now is one step up into the LP level. By LP level, I mean the best recordings properly molded in good vinyl and perfectly maintained. This is not easy, BTW, even if we bought the LP first hand. Anything less is likely to be blown away without mercy!  
 
Why not get started Welborne and see how it goes? You could always have hardwares modified to your heart's content afterwards.

I also believe that digital audio files are best left intact and no conversion is necessary, be they bit conversion or sampling changes. Albert's (mdlover) eXD is able to do just that, to wit, native processing.  
 
You don't have to look overseas for the right DAC if you don't mind the eXD's modest price tag. What's more, you have the benefit of excellent repairs in case servicing is ever required, done by no one but the original designer himself.

With the latest 5.2 JPlay in place, there appeared no way by which I could achieve the same level of musical coherence attainable with my own set up. There was a pervading sense of digital "presence" no matter what setting I had with either JPlay or JRiver. It could actually be rather exciting provided you don't listen to classical and you don't mind having listening fatigue within 30 minutes.  
 
As a last resort, I had to uninstall the update 5.2 and replace it with my old copy of 5.1, oh yes with JPlay's consent. What a great relief!
