Hi, Everyone !
I Have found out what the problem was!
To my Dac and Tube bufferstage i have an external powersupply X-PSU
v3
I Unplugged the X-PSU and plugged in the orginal powersupplys that
came with the X-dac v3 and X-10 v3...
Viola ! Wow Now i can´t hear any difference between
That's a shame as the x-psu sounds a lot better (at least in my system
it does) than the standard wall warts...
I wonder what might be wrong with it...
At least I wasn't able to reproduce your findings - so mine must be
working fine :o)

Using the 6.5.0 release, my SB3 has a volume range of 100 now, instead
of the original 40. I presume that to mean that each step represents
0.5 dB change in volume. Assuming I have the volume control effecting
the digital output... if I wish to reduce the volume from a maximum of
100 so that in
Skunk, About the channel separation iam not sure, But i have done some
more testing today.
I prefer the 80%-90% volume setting because the music sounds more open
and less harsh treble. (More tube like sound)
About the Fidelity Recordings that are properly mastered, I prefer
the reduced volume
Well - interesting results so far...
(SB3-TACT 2.2-Altmann JISCO+UPCI-MF X-DAC v3+PSU, MF X-10 Tube buffer,
Chord Signature interconnects)
Firstly, I set the TACT peak indicator to 0dB to see what was going on
with a few CD's. First up was the 1st Killers Album (Hot Fuss) - I took
a wild guess
Reducing the digital output on the SB3(6.5)from 100 down to 95
helps deal with these poor recordings and stops the TacT's input
indicator from flashing. Reducing the digital level down to 80 does not
make the music sound more open.

Is my Dac broken or something else wrong?
Probably nothing is wrong. Try it at 90% and see if it still sounds
good. If it does, you've probably discovered one of the dirty little
secrets of digital sound processing - digital overload, as explained
here:
Tanks for the link/replay Kim!
But if Digital Clipping is the problem, then must this happen in my
dac because of to hot signal?
Because if the signal is Clipped in the mastering there´s nothing i can
do about it. (The distortion is already there)
But i have found this 80% effect on all my
I'm going to try this (lowering the digital level by a small amount)
later as it requires quite a complex comparative listening session.
Having read the paper, one of the issues is how the DAC handles signals
at 0dB - regardless of they got to be on the CD. Obviously what is on
the CD is fixed,

How are your digital volume setting?
My SB3 with the 0-100 volume scale is set to 90.
My TacT RCS has a red light on the front panel that can be set to flash
on digital zero on the input (i.e., clipping or near clipping). I just
turned down the SB3 until that light
Whoo! - I have an RCS2.2X as well...how do you set up the clipping
indicator?

Sorry - I remembered you have to set the level detection threshold
(doh!). Mins is set to -95dB so it acts as a music is present
indicator...
However, I also remembered that I have the max level on the TACT set
to -6.9dB...so I'm already doing the 90% thing in the digital domain
before the DAC.

You might think so, but you're not. The RCS has an AD1896 asychronous
rate converter on the input that

to reduce the digital level in the SB3 before it gets to

The Sound is more open and wider, Better channel separation,
I fully trust that it sounds better in your system, the trouble comes
when trying to understand how channel separation can be better when
stereo crosstalk is louder. [settings 30/20 on the following equate to

So where does the TACT level control fit in? - I assumed it was before
the AD1896..are you saying it is after?
Also what exactly is the level sensing measuring - I'd assume it was
the level on the way out of the unit (so you could see if the RC was

Thanks Kim...I'll check this out tomorrow!

Hi omega, I'm confused by this above quote... Shouldn't you be
comparing the SB3 analogs, and your DAC, each at 80% (not DAC at 100%)
- as you were advising?
