Mr Perceptive-
Looked at the Meridan forum thread and agree totally with void's
statement:
"I don't have experience with Meridian on Big Ben, but I've tried
several 'high-end' CD-Transports and DAC's with the Big Ben. With most
transports it offered a good improvement (especially with bad

topster,
The first time I compared the switching PS to a linear, both were
plugged into a BPT balanced power conditioner. The BPT 4 has multiple
transformers inside to isolate each source component. The amps were
plugged into a separate BPT conditioner.
I heard a difference between the switcher
Hi,
One thing that hasn't been mentioned (maybe it has and I missed it,
but...) is whether the noise generated from the SMPS could be polluting
the power lines for OTHER components.
It might be interesting to see if there is still an audible difference
in changing power supplies if the SMPS is f
Mike...what does the rest of your system look like? When I tried the
Benchmark in my reference system, which is very transparent and fast, I
found it to be very edgy and analytical; but when I tried it in a system
that was more lush, I found the Benchmark to be a far better fit...

Here are my own measurements. I still disagree with the idea that the
DAC's performance can be audibly improved by changing the external
supply.

The SB2 is my favorite toy too! I'm completely pleased with my
purchase, and would recommend SB2 to anyone that has a network and a
stereo. I think the SMPS included with SB2 is a good choice, adds
value, works well. A good linear supply would add too much too the
price. For those that want to
Max,
I am in NO WAY dissing the SB2.
I am very impressed with what Slim Devices has come up with.
I CAN hear a difference between the stock switcher and a linear supply.
I decided to take a look at the power lines with my 'scope yesterday to
see if I could see a difference that could explain wh
Please make sure that some of this conversation is mirrored on
AudioCircle! I hate to see my favourite toy dissed. ;-)

Absolutely, and how _long_ is the ground lead, how are signal and
ground attached to the probe, the type of probe, including loading,
etc., the type of scope and front end amp.
Ringing (which you see in the photo) can appear to b
Without time-base and amplitude-range settings for the scope, this tells
us very little. I assume (and hope) that the settings were the same for
both pictures.
