My 7.0 "clicks" when a signal is started or stopped... just for the record
 
Just from the DAC itself though, nothing through the transducers.

That's definitely signal "lock"...if I stop the CD7 the signal lock "click" (signifying an "unlock" status) will be heard if no signal is sent from your transport to the DAC after a minute or two. Mine does the exact same thing independent of the switching function for the units that have more than 2 inputs.

Correct, but the 7.1 does not.

What's your best guess about the changes between the 7 and 7.1 WRT the digital input PJ ?  Have you had a close long look at the internals yet ? Any pics you can send me a link to ?
 
I know the analog and ACSS stages have been updated in the 7.1....I'm curious about the improvements as a whole but also details on the digital input changes . I know this is asking a lot PJ since your mem of the 7.0 has faded, suffice to say TIA for any relevant info and what's your current assessment of the 7.1 thus far ?

PS : Anyone have a spare V5 DSP-1 in N America ? PM me please.

The 7.1 Is now discontinued.

3th June: We had to cancel the PCM1704 order from TI. The Reference 7.1 had be discontinued.

Yeah I just read that...what a bummer.

I feel so sad about that.

 
I own a Ref 1 and want to upgrade to Ref 7.x in the near future.
 
Now it seems the PCM1704UK is discontinued.

We place the 4K pcs order and  made the earnest money to TI agent  at mid of Oct. in 2010 .
At first they replied us delivery at mid of March in 2011, later they change to end of April.
But in May. , they still can't delivery the chips.
 
Here is TI agent first email at May
_______________________________________________________________________________
We are in process of finishing and testing this solution, but we do not expect to be able to ship until June.
 
If the customer would like to consider alternative parts, the only pin to pin options are other PCM1704 products.  We have PCM1704U and PCM1704U-J in stock, but these have a difference in performance.
______________________________________________________________________________
 
Later they send the second eamil
_______________________________________________________________________________
 
Thanks for your kindly feedback.
We do really have no wafer to support to pull in now.
Please kindly try to work with customer if possible- For a high quality audio converter, at half the price, we suggest the PCM1792A (or the hardware controlled PCM1794).
Please kindly let me know if you need any technical support for technical questions about these alternative parts
______________________________________________________________________________
 
Two days early they return the earnest money to us without 2 cent accrual .

Perhaps you could try the PCM 1794. Neko Audio uses it in its D100 DAC and all the reviews say it is very good, it has a natural sound and reproduce very well acoustic instruments in classical music. I am sure you can make a very good DAC with your implementation.

There are very lot TI samples in China.
I have diversified TI produce ΣΔ  DA chips.
But I don't like their sounding, quite a different than their R2R DA chips. I prefer the WM8741.

KingWa, what about your ESS ΣΔ implementations? Are you planning any future products/upgrades with ESS90xx chips?
 
Do you prefer WM8741 over ESS9018 too?
 
I am really sad PCM1704UK are no more in production... Wonderful natural machines... This also means Reference line DACs we have are among the last produced specimens of PCM1704 breed.

Does 110 volt version sound different to 240 volt ?

That's a question better asked for Kingwa since I really do not what changes might have been made to the digital section.  All I know is there no actual clicking on signal lock, and there seems to be less variance between transport quality now.  Maybe the DSP-1 was upgraded to V6 without anyone knowing about it?'
 
I'm not using the ACSS stages.  I had cables built and ready to test for my amp, but Audio-gd, without informing me decided to switch from the 4-pin XLR plugs (as shown in the original Ref 7.1 picture) to their new 3-pin plugs.  To this day they have not sent me the proper connectors for me to fix those cables.
 
I have mentioned in the 7.1 thread about the sonic differences I've heard so you should check it out.  Kingwa addressed the issues mentioned by some people in the Ref 7 loaner thread, and it's a better sounding DAC because of it.
 
It's a shame that yet another product line is going to be discontinued by Audio-gd.  This time it seems like it was beyond his control.  Not too many people own this DAC so there won't be too many reviews of it out there (not that it matters much now anyway; even if you wanted one you can't get one unless it's on the used market and I doubt any 7.1 owner is going to sell theirs unless they buy some rather expensive name brand to replace it).
 
 

 

[tme110]

and all mention of the ref 7.1 and ref 5 have been removed from the web site.      From reading above I'm guessing there will be no more AGD R2R dacs?
