Yeh , the 518 does have flavours of dither , up and downsampling etc.
I use a Z-sys Parametric Eq in the effects loop of my transporter
sometimes , and have used a TACT. However these devices dont really
claim to reduce jitter and most likely add more , however their effects
on sonics are so many
Thats more like it Rodney, you use the digital effect loop for a
purpose, digital eq and room compensation and other goodies, nice setup
btw.
It's cost benefit, as you said.
Ted's original Q was about using the loop for nothing (as I see it )

I have used many of these devices. They do do one thing , and that is
change the sonics. either you like what they do or don't - try one if
you got one on hand. I found the Meridian 518 was one of the better
units out there , but I run meridian speakers so there might be
synergy.

Makes more sense to me to upsample your music in non-realtime (can
Audacity do this?), and use the Transporter 'properly'. This allows
the potential for better upsampling, as you are not restricted by the
machine's CPU speed, and eliminates all the jitter problems that other
have mentioned.

They all change the spectral distribution of the jitter. A bit
different from eliminating it. Good to have independent
It's a matter of context (in reply to rodney ), in this particular user
case it's a bad idea, read the first post again (out from the TP and in
again ).
The TP is a clever work around of the problem clock signal extracted
from s/pdif, combine the source and the DAC no spdif interface no
problem.
The latest Beresford Dac (MK6/4) effectively upsamples to 24/96 before
it leaves the SPDIF.
Upgraded mine recently - big difference mainly noisefloor pretty much
gone.

Not only that, but..
Many years ago, we had the unfortunate opportunity to measure one of
these jitter fixin' devices.
I have never seen a piece of electronics knock every VHF
Monarchy, among others, makes very good jitter reduction/upsampler boxes
(i.e Monarchy DIp 4896 Upsampler) that go btween a transport and a DAC.
In the case of the forementioned Monarchy one, it also upsamples to
24/96 if set accordingly. My question is this:
Since the Transporter's digital out
You wouldn't want to do this, it would probably cause more jitter since
the jitter as seen by the onboard DAC is lower than that of the SPDIF
board.
The DAC is also a delta-sigma style DAC and gets no improvement from
upsampling.

The latest versions of the TP firmware do allow for an external digital
effects loop, so at first glance this could be done. I'm not sure,
however, if it would work with an upsampler in the loop. If Sean or
someone else doesn't pipe up and say yes or no, I have both a
transporter, and an
Good point about the spdif interfaces being an unneccessary source of
jitter. Duh! Guess I was just asking cuz I'll likely get a DIP 4896
Upsampler for my soon-to-modded Oppo (for digital hirez output of pcm'd
SACD at 88.2k and of course DVD-A at 96k) and wondered if it would add
any value in
