Audio-GD Reference 7 - the new flagship DAC

yes a commercial product such as this would suit the job better since it has multiple output. I also notice this item is quite commonly used to clock other highend product such as dCS

Hi
 
Are u using the neutron star clock to feed the M-audio only ? how about parallel connection to the transport and DAC, so that both clock is synchronized.



I use Neutron Star on master clock in ProFire 610 and D-Clock for JetPLL chipset.  ProFire 610 is 1394 firewire unit and it is Async.  For RE-7 or RE-7HE, you do not not need clcock because 1704UK is Signmagnitude DAC chip.

The Neutron Star outfitted with a worthy PSU can set one back a cool 800USD easy....and likely 1K USD with a nice chassis. Cool mods no doubt BigMac but way too rich for my meagre resources.
 
Peete.


To maximize sound quality of Audio-GD Referecnce Series DACs, I think we may seek to invest some $$ on source area.  For PC-Audio base, I think DDC and to use i2S protocal between DDC and DAC is one inverstment to maximize sound quality.  ^^*

Hi big mac
 
 
have u got the mod for the NFB 7 ?
 
After the mod, the channel selection switch still works ?
 
 
I am eagerly awaiting.

Yes, I am working on NFB-7HE which is two pieces version of NFB-7.  It seems working fine.  (Update: it is not possible because of ESS dac IC)  For selection, you can choose any input to make i2S input.  My case I use USB selection to be i2S selection.  One interesting part is I can hear the differences by methods of input between AES, Coax, i2S, etc.  My opinion, i2S is by far better.  ^^

Hi,
Good coaxial can help to improve the sound. I believe yr comparisons has taken into consideration the good cables used in the coaxial vs the I2S.
 
 
my understanding is I2S is recovered from SPDIF. Since I already use audio-gd CD7FV, do u think with the M-audio + neutron clock and I2S will send the CD7FV packing ?

I have a couple of high-end digital cable from Siltech and it is still could not compare with i2S.
 
CD7FV is CDT which is same as DDC for Audio.  CD7FV may can mod to install i2S sending board to connect to DAC.  DDC is for PC-Audio and CD7FV is for CD listern.  From Audiophile point of view, both PC-Audio and CD listern are different tastes and hard to say which one is better.  If I were you, I will keep both.  ^^
 
Also for NFB-7, I was not luck enough to figure out to work with i2S.  Because ESS dac IC is built-in for every digital signal input and it will be very hard to mod.  ^^;;

 You'll get no argument from me as far as seeking out a HQ transport source as part and parcel of getting the most from Kingy's DAC's (the REF series)....I have a DIY modified CD7 although I would consider an I2S pathway between the CD7 and RE1 if I can manage it for a modest sum. The Neutron clock for me is out because of cost (at least for now).

Another solution to raise the transporter up is to use isolation cones. Apart from the extra space for cooling they improve the sound a bit too. The best isolation device i've used is the cheap vibrapods but they dont lift the component very high unless you use the matching cones that go with them. I tried them in my system to prove to my friend they wouldnt do anything and then ended up buying them straight away!



That's been my experience with vibrapods as well, they're pretty nifty!

Its a pity NFB 7 cant do I2S.
 
Nevertheless I will get this M-audio and the possibly in future a better clock. I will still maintain the CD7FV and the m-audio is for hirez.

its more of a pity people are spending thousands of dollars only to not be happy because of things most of them do not actually understand.
 
Actually, it is pretty sick if you think about it. People are inventing problems.
 
Anhedonia is not fun, and is a mental disorder to varying degrees. A lot of people here put great efforts into making sure they will not enjoy their purchases due to unnecessary anxieties.
 
If you can't enjoy your gear without constantly "upgrading" it, you should just return it and figure out what you are really chasing, because it is not sound or music... It is probably actually dopamine.

ccshua never said he wasn't happy with his setup. The way I think of it is like a cook who wants to make a dish better. Maybe he keeps trying because he has issues, or maybe because he just has a real love for food. But either way, would you want to discourage that cook from experimenting? It's how new dishes are made, and how new discoveries in other fields are made.

Well I was more just talking about the general mentality around here nothing personal with ccshua really and more just that he used the word "pity" which I am increasingly associating with head-fi.
 
It is a real pity people spend large amounts of money only to want more...and more... and more. Can't say I have never been guilty of this in my life or that people are actively aware of the damage they are doing to themselves.
 
If these wants do not have an end, I think there is a real problem that is not associated at all with "golden ears" but rather the reward that comes with a new toy. If you follow the logic that dopamine is release as a reward, and a new toy would/could cause the release of dopamine the line between hi-fi hobby and drug addiction becomes scarily blurry for some people around here. Enjoyment of music does this, so we are all guilty on some level, but some (many) people's focus has shifted from the reward of buying rather than listening in the aim of feeling good.
 
Tweaking offers people a way to theoretically make improvements and thus a situation to feel rewarded about - they made their gear "better". For those who are fully blinded this is great as they have a perpetuated sense of happiness even if it is complete lunacy. There seem to be those who are in a circle of losing though - it can never be good enough, there is ALWAYS something that could be better.
 
I would never want to associate a pleasurable activity with one of the biggest paradoxes of life - happiness. Or "Paradox of hedonism".
 
The less we perceive as problematic with regards to music, the more we should be able to enjoy it... which is probably why I have friends who are also musicians that do not buy into the hi-fi thing and probably enjoy music even more than I do..  because they are not worrying about the quality of their experience, they are simply enjoying. I like where I am now which is kind of in the middle, I have high end gear but I refuse to worry about the superfluous.
 
I also don't doubt for a second my decision to purchase my phoenix and Ref-7 were more to relax anxiety on some level about performance, rather than lack of ability on my previous system -my previous set up was great (and so is this one). It has not increased my capacity to enjoy at all (well maybe my LCD-2), it has merely reduced reasons to worry about my system if you get my drift. It is expensive, good looking, and over designed so I "know" I am getting a good performance. Whereas before I was constantly wondering what a better source and amp would sound like. It ruins the experience if you let it. I know I did for a while. Know that I have spent crazy amounts of money I no longer feel that way and might actually go back down to a cheaper system.
 
All in all I think it was a great purchase but I am very aware of the true motives which many here life to actively blind themselves from.... Why else would you tear apart multi-thousand dollar components to throw in better caps and ETC? Why else would you indulge is a huge luxury at a time of economic crisis only to wish it was more, or you had spent more on another.
 
Finally the supreme irony lies in the fact that most of these tweaks and changes do not make a sonic difference, rather a psychological one.

Good post.  And there is no proof that I2S will sound any better at all because every implementation is different and there is no universal standard that works on all gear like S/PDIF or AES/EBU.  If you talk to some engineers or people who do mods for a living (that aren't trying to sell you a bill of goods) they will tell you it will most likely make matters worse, as it was never designed to transmit a signal over distances more than a few inches.  Where it provides a benefit is when used with USB to I2S conversion, and only when done at the receiving side right next to the DAC chips.  Money is better spent improving your transport's power supply and clocks, or to build a battery supply.
 
For the record, I have listened to a PerfectWave DAC and PerfectWave Transport using I2S, and compared it to the Bridge, and to the AES/EBU input, and I heard no difference between the three, and I usually hear extremely tiny differences between connections.  What did sound slightly less good was the USB input.  That doesn't mean there won't be differences in other gear using I2S, but you can get a BNC S/PDIF or XLR AES connection to sound every bit as good if your transport/source is up to snuff.
