Thanks Sean, Pat and Wirrunna,
Sean: indeed, I am using the coax S/PDIF... I will change it to
analogue... If I am not mistaken, the DAC's in the amp and the
squeezebox are the same..

just because I am listening to music.. :)

Thanks for the feedback and the link. Used to be an EE many years ago,
and brain is getting befuddled these days, but surely any digital

By definition, reducing the volume by reducing the digital values will

If your system is like mine, you will find that this subtle effect you

Just to confirm, if the settings are default, and the source file is

Actually what I think is happening here is that an electrical transient
is causing a momentary error on the s/pdif connection. That's about the
only explanation for a momentary dropout like that. Are you using coax
s/pdif?
If so, try switching to optical or analog.
It's true that software development is not the same as mechanical
engineering. :)
The stringency of the process is generally somewhere between mechanical
engineering and film producing. However, SW dev is different to both and
the exact kind of process used depends on the application.

Ripping a CD with EAC is (AFAIK) the better transport you can imagine
(yes, a 30$ computer drive can beat a 2k$ audio mechanics).
That's just the theory and there is too many other parameters in

- replace SB psu by a linear one
- use

I checked what you suggested and everything seems to be the way it

that one provides enough amplification of the signal of the SBR. Maybe

Thanks for the reply. I would agree that in the case of a 24 bit DAC,
driven in the manner you describe, there would be no loss of resolution
until the volume was reduced to 1/256th of the full volume.
I am however using the DAC in my Krell. So the quesion is whether the
SB3 outputs 24 bit
The S/PDIF default is 20 bits and only equipment that supports 24 bits
sees 24 bits. I'm fairly sure the SB3 puts out 24 bits...but I'm not
sure about the Krell.
BTW the issue with the digital volume control isn't bits (when working
with 24 bits none of the 16 original bits are lost with normal
A couple of points.
First, you say you haven't changed any of the settings on slimserver.
By default (unless this has changed, in which I'm sure someone will
correct me) SS encodes WAVs as FLAC before sending them to the
squeezebox/receiver. That means there cannot possibly be any sonic

I presume you've checked to ensure replaygain or smartgain are not

Are you using the same SPDIF cable when comparing your CD player vs.

Yes, it has absolutely nothing to do with the amp drawing too much
power. You never use it at maximum anyway.
Electrical items like dimmers, refrigerators etc. might send out pulses

Nothing special happens at 1/256 volume. Best practice is to set the

I ordered a transporter and spent the better part of the weekend
listening and comparing it to my SB3. For most of my music I could hear
no real difference. With other, better recorded, music the transporter
sounded a little more resolved and clear.
I really like the additional hardware features
That V8 amp looks cool. I wonder what the torque on that thing might be.
Seriously though, If he was really and critically listening some music
there, no way he wouldn't have noticed resonance coming from that
