Anyone who starts to buy into this stuff needs to do an honest blindfolded
A/B test with outside control of the sources to reliably demonstrate that
they can pick out the differences.

As an example, in the case of cables, I have not yet met anyone who could
blindfolded tell the difference between decent quality cables that had good
connectors (available for $10) and $100 a meter cables.

The isobar is just a line of surge suppressors from the TrippLite
corporation. AFAIKT, they are just passive surge suppression devices of
typical design with relatively high quality of construction. Not sold for
filtering.

I use a Brickwall surge suppressor. They are of a different internal design
and do offer some filtering.

Clean power and power supply upgrades are popular DAC upgrades in the
audiophile community. There is no doubt a lot of hype and even blatant
snake oil, but there are also a lot of people who purport to hear
differences. From what I understand about the D/A conversion process, it
makes sense that rock steady voltages and deep current reserves could make a
real difference in the fidelity of the resulting analog signal.

I think a reasonable audiophile SB tweak to try would be an upgraded power
supply. Something with tight voltage tolerances and overrated current
capabilities. Maybe Sean could provide some guidance on how the
stock unit was spec'd and what we should look for when trialing uprated
units. If good results are found, could be a product opportunity for
SlimDevices.

Definitely two schools of thought on cables. I hated to even bring it
up as it always seems to fire up the old arguments.

For anyone who's not been down this road, let's just say there are those
who hear differences and those who don't with plenty of scorn from one
group to the other.

For myself, I have heard differences. And it's not always the expensive
"special" stuff that sounds best. If you find it interesting, I'd
encourage you to try out different configurations. Everyone's ears,
rooms, equipment, perceptions and tastes are different.

The cable forum at audioasylum.com is a great place to get your feet wet.

How long should special cables be to sound best ?

I don't know. You might as well ask what color they should be? Of what
composition? I don't care if they are a mile long, radioactive green
and composed of wood cinders, as long as used in my system, they sound
great to my ears.

Why don't you try auditioning different cables for yourself and let you
ears guide you? Or if you choose to believe that this is a dead-end
road, for fools only, why not let the fools continue their quest in peace?
