Lumin T2 with Anthem STR preamp signal going through both DACs?


To use bass management with my Anthem STR preamp, I have to convert the analog signal back to digital hence then using the Anthem’s DAC to process the final signal.

So in essence, the signal is being "dac’d" twice ?? That seems detrimental to the signal even with good dacs.

I did not know this had to be done to use subwoofers.

Is that normal and has this just escaped me all this time? Or am I missing something?


Addl info:
-- The setting on the Anthem you must turn on to use subs is in the Input settings and called "Convert Analog 32/192"
-- The subs will not turn on if that setting is "off"

Yes, unless you have the Anthem set to analog or digital bypass, the  analog  signal from your T2 is  altered by the DSP of the Anthem.  IMO, this degrades the signal.  You can try it both ways and see which sounds better.  I found putting my Classe Sigma SSP in digital bypass mode sounds much better.  Of course you lose bass management this way.  I got around it by connecting my suvs to the RCA outs from the Classe and manage  the Bass directly with my JL Audio F 113 sub.
I think you will get the sound character  of the T2 either way.  However, in my experience, using DSP alters the signal somewhat.  I found using digital bypass made the music much clearer and more natural.  But I would try it both ways and see what you think.  As others have mentioned, it is possible you may not hear any differences.
I tried it both ways and ended up preferring the connection through balanced inter - connects with no DSP. It was a little more dynamic that way as opposed going through my Wolfson 8741 chip in my Classe. However, my XLR cables are much better than the USB cable I have. Also my Classe DAC can’t decode DSD and MQA.  I would try it and see what you think.
Not sure if you stream tidal, but I don’t think the Anthem DAC is fully MQA compatible, whereas the Lumin T2 is.
If you are using the Anthem DAC via USB from the Lumin, you are sending a digital signal, not analog.  Thus the Anthem will only process it once, as a digital signal.  You are correct that the Anthem will not, however, be able to decode  a MQA signal.  

Dtximages,

I know this an old thread, but I am curious if you returned the Lumin. If so, what are you using now?

 

 

 Nice.  I had the same issue with my Lumin T2 and my Classe Sigma SSP DAC.  I did not like the idea of music going through 2 different DAC’s.  However, I still have the Lumin, but I set the Classe in digital bypass mode, thereby using only the Lumin DAC.  While the Classe DAC is also very good, I am pretty happy with the Lumin.
