Sean, if the Transporter measures up to the specs you have published for
it, then yes it will smoke my NAD CD player, and most other CD players
to boot.

If you replace the SB by a CD player or other source (using the *same
cables and the same inputs*), do you get a significantly lower level of
hiss?
By the way, when you say there is a lot of hiss, do you mean when the
SB is idle, or when it's playing something?

When I was comparing the noise floor of my SB3 with my CD player, (which
is a NAD C542 by the way,) I was using identical cables via another
input on my preamp. I tried swapping the inputs on the preamp, and the
noise floor followed the SB3. I tried unplugging the CD
I am not an engineer so I hesitate to make this statement, but I think
that you may have a mismatch between the gain that is being applied by
the SB3 and the gain of your amp. Even very high end pre-amps that
are very high gain will match poorly with high-gain and high sensitity
power amps.
I seem to recall a post many months ago when Sean Adams stated that the
SB3 performs best with the display on bright. IIRC, it was something
about how when the display is off or dimmed the input to the DC-DC
converter that powers both the display and the analog circuits
approaches its minimum
I think the key point here is that the hiss only seems to occur when the
SB3 is connected directly to an amplifier (not an integrated amp) using
the SB3's analog outputs.
I also have noticed a significant amount of hiss with the SB3 plugged
directly into my PSAudio Trio A-100. However if I

Has anyone found a solution to this problem?
Someone (not from Slim) suggested setting display brightness to
zero/off when idle. Then it wakes back up when you hit any button.
As much as I like the VU meters, I find this to be the most
aesthetically pleasing setting

Thanks Skunk but I already have the display off when idle, no go, still

that can only be addressed by Slim with a software or running hardware
change?
If so, I did looped the RJ-45 around a ferrite
I had a similar experience - a surprising amount of hiss being heard
emanating from the SB3 analog outputs compared to my CD player's analog
outputs. I would guess the difference was about 15 dB. This was evident
when turning my preamp volume control up to about 12 o'clock - a
position that is

It would be sure nice to hear directly from SlimDevices if the DAC is
indeed the cause of the hiss and if the issue can/is-going-to be
addressed or not?
They will probably ask what you're using for external attenuation
before the power amp, since that's the recommended

One thing that has been noted before is that, without external

other devices:
I only say this in order to let you know that perhaps indeed you have a
problem elsewhere in your signal chain, but fact is I get absolutely no
noise - 0 - when no music plays or during silent passages, regardless of
how loud my amp is turned up (110w). (Not to be dismissive; again, just

It's exactly as you described the noise floor, I've turned my amp all
the way to the max and paused SB3 (not wanting to kill my speakers).

I've heard white noise only once or twice, and
disconnecting/reconnecting the power seemed to fix it. Did you try
that?
You might also try plugging the SB3 into a different outlet than the
amps to see if that helps, maybe run an extension cord just to

SB3 is configured to use digital volume (I think that the analog volume
control of SB3 is at 100% at all times). The situation is the same if I
lower the digital volume to 10 (0-100) instead of having it paused.

Are you sure...really, really sure...that it's not your prior equipment?
I assume you're talking about an integrated amplifier.

Last night I tried using SB3 without the preamp. The noise coming from
SB3 was incredibly loud! It was like, wow, who recorded the sounds of

The amps were NAD C370's (two in a 300W monoblock configuration).
