The final production unit is now under the final
test - critical listening!
Dual transformers to separate the analogue from the digital processing
Provision for multiple inputs, both balanced and unbalanced
Last and certainly not least, the costly analogue refinement which leaves you in analogue bliss…….
The caveat: the final product is better than all 3 prototypes that I have relentlessly assessed. In all respects, I mean.

Ivan,
Is JPlay still available for download and supporting JRiver? Yup, LS3/5A and Leak live in harmony. They are happy couple. |

For the computer, I'd recommend i7 along with 16G ram to make room for any future developments. I suppose you don't use CAS for a short period of time and honestly I trust CAS is here to stay for a long time to come.
2 years ago, I wouldn't hesitate to ask you to go for JRiver (the media player) plus JPlay (the sound enhancer), but now the 2 companies are in brawls with each other, so much so that they become mutually exclusive. Hence, I know not what to recommend now!
Using JRiver alone you may end up with quite a bit of digital fatigue unless your repertoire is confined largely to pop. Nevertheless, this player is remarkable in the filing and classification of large quantity of music files. Mind you, the collection easily goes beyond 2T and if the filing is poor, you would never be able to find what you really want to listen.
Any good suggestions from other buddies here?

| Hi, I plan to set up CAS system (at last!). What is the recommended spec/model for the computer source? From the old posts, it mentioned i5 processor, 8 GB RAM. I wonder if it still stands or there are other viable options. Thanks. |

@Albert
Congrat for the review, quite nice, we are still waiting for your DAC in California :-)
We had a chance to mess with UpTone's linear power supply today, using it to replace Auralic Aeries standard outboard power supply (which was already good), the UpTone JS2 was quite impressive. An R-core + choke filter fundamental. The result was lower noise floor, lower digital noise, separation improved, music flow better and more articulate. Not cheap but I guess they don't ask for $1000USD without giving something ...

My second visit to Arthur within a couple of weeks. This time 2 more friends joined me to find out what the fuss was about regarding Arthur’s CAS system, mdlover, the local DAC pioneer and Bigchan, a veteran audiophile for over 40 years.
The focus of attention falls upon one piece of equipment, the expensive Bacch processor. Its strongest feat is the elimination of crosstalk which would ensure perfect imaging between the left and right channel.
Here it goes:-
“The BACCH®-SP (SP stands for Stereo Purifier) is a very sophisticated digital audio processor. It is easily the most advanced audio processor in existence. Inside the BACCH®-SP is an i7 powered computer that will allow owners to design their own BACCH® filters on the fly. The BACCH®-SP allows the owners to create a new filter with a click of a button with the dedicated iPad controller.
In addition to BACCH® processing, the BACCH®-SP has an advanced head-tracking function. By using custom software and a motion detection sensor, the BACCH®-SP can create a new BACCH® filter that allows perfect crosstalk-free stereo playback when the listener moves around. The advanced head-tracking features will accurately track the listener to sub-millimeter accuracy. The result is an even more convincing virtual reality with perfectly stable stereo images with uncanny realism.”
And the rest of the electronics include digital crossover which split the signal for the 4 way speaker. It also serves as the pre-amp. An accurate clock to synchronize the digital bits and pieces and of course the Mac computer for the program source.
There is tangible improvement over the sound I heard last time. It must have taken Arthur a bit of work to further refine what has already been very good. Things are now more transparent thereby drawing listeners closer to the music. Nice work Arthur!

A visit to Dr. Cheng on Saturday afternoon. I heard stories about his newly constructed no-compromise speaker housed in a towering cabinet popular with modern speaker design. It was a huge success over the old speaker I heard 2 years ago.
Arthur has been one of the top pioneers bring CAS into HiFi. After years of refinement, it has developed into a very elaborate CAS system whose details I won’t be able to accurately report because I am still in the learning stage. All I can say is that the sound is very smooth, tonal balance very well constructed and there is none of the digital glare I’ve found in Apple based set-ups. Bass response is impressive, extending well into the 30 Hz hell mark.
Here it is, the highly polished speaker
4 Class D amps to actively drive 4 way units of the speaker
4x10” bass at the side, 4x 8” mid bass, 2x mid range and 1x super tweeter per speaker.

Cadiver loses no time to take a look at the tube DAC. He loves the sound of the new DAC so much but he hates to wait another 2 years before it is available.

Pop is all about the atmosphere, the beat and the rhythm Does a listener really go deep in identify the brand or make of the guitar or whether is a Yamaha or Roland keyboard?
I don't think so lor! In classical and Jazz, the music is made up of the emerging or fading sound of the musical instruments. A high level of details needed to be heard for the listener to recognize the passage.

digital guys don't even want to admit valve still exist
_______________________________________
Digital guys don't care about musicality as long as the distortion curves look good.
Strange as it may suggest, you can tolerate digital edge on most pop music but you'd be hard pressed to have half of that edge on a string orchestra. And if digital guys listen to pop most of the time, they may not be aware of the digital edge at all. Some may even mistaken this digital glare for "great presence"!

Why then is the indirect method which turns out better?
------------------------------------------------------------
I soon will be joining the CAS family and I am sure I would be more confuse than u lor!
Pick any man written literatures on digital recording or digital music reproduction which is what I have mainly been reading recently to hopefully get a stronger grip on what 0 and 1 is all about in music reproduction. Not to my surprise that almost all of the available content is about technological advancement in handling data and not losing an ounce of it. And deep down into the writing, the heart of the matter just keep went on about the excitement of convenience in storage and the speed or resolutions when retrieving the data, right? Hot really much of any mention about the vibration and air that produce the sound we all love to hear lor, MUSIC lor!
If an add on yester-year technology valve buffer stage can bring the listening pleasure a big level up in a DAC, not hard to see how much care is missing in some of the current high end digital inventions lor. Some digital guys don't even want to admit valve still exist lor!

I end up having two versions of Aida, one ripped from CD and the other downloaded from the Decca site. It is the same recording and yet there are differences so obvious that it's hard to ignore.
The one ripped from CD wins. Download is a direct data transfer and CD is an indirect method which has to go through quite a few processing stages. Why then is the indirect method which turns out better?
Since both files come from the same master and digital files are supposed to be the same no matter how many copies are made. You don’t expect your bank account to gain a zero in front of the decimal when you request additional copies, do you?
