I have been using the Boss 3 pedal case for quite some time with the 9 vole power supply daisy-chaining 3 pedals. I use this with the pedal steel.
I recently made a fly rig with 6 pedals and a 1 spot pro CS6 isolated power supply.I use this for 6 string guitar and noticed the reverb and delay sounded fuller and more robust. I was using the same 6 pedal rig with a daisy chain power supply and there is a definite difference with the isolated power supply.
Thoughts?

| Galvanically isolated outputs is an ideal starting point for eliminating noise and "GND pull and loops". From what is written ( https://truetone.com/cs6/ ) it looks like an ideal power supply for multiple effect units, equal to or better than having one supply for each effect unit. |

What were you using for a power supply in the daisy chain configuration?
What is the voltage and current rating of that power supply?
Did you measure the voltage output of the daisy chain supply with the six pedals attached?
And just curious, what are the other pedals and their order in your signal path? |

I was using a 1 Spot with 6 daisy chain adapter. The pedals did not exceed the millivolt capacity. The isolated power supply is much better. A bit pricy but it makes a difference.

After using my new pedalboard with the Trutone isolated switching power supply I will never go back to a wall wart daisy chain power supply. The effects pedals seem to be more robust and the entire rig is quieter.

Just to clarify, this should be "milliamp".
I have a pedal board with around 8 pedals in front of the amp.
I have another pedal board with 5 in the effects loop.
I got tired of batteries and wall warts a few years ago.
I finally built a separate supply for each set of pedals.
The supplies are regulated 9 vdc, regulated, nothing fancy.
None of the effects used are digital, they are all analog stomp boxes.
Each set of pedals are daisy chained.
It all seems to work well, seems quiet.
I have never had a problem, EXCEPT..........
A few years ago I bought a cheap off brand Univibe type pedal.
It did not want to play well with the others.
I dug around inside, added some extra filtering to it, and it now works with the others. (By the way, this pedal is a real "piece of work". A small boutique type builder, I don't know if they are even still in business, the circuit boards inside the pedal are not securely fastened down and are just kind of floating around......you get the picture I'm sure.)
I have had maybe 1-2 other pedals over the years that also for some reason want their own dedicated supply. Once again, none of these are digital.
So my dual daisy chain set up seems to work fine for me.
I really can't vouch for if an isolated supply would work better for me.
I suspect that it wouldn't be any worse for sure.
Would I notice a difference? I don't know. But since my set up is working for now, I'm not going to "fix it".
One Spots: I have never used one.
I have read a few posts scattered over the internet over the years about them causing problems, so I've always been leery of them.
I have never seen a schematic of one.
I bought one used a couple of years ago.
I got a super deal on it, and my intent was to take it apart and find out what's inside.
But it's brand new, and I can't find it in me to rip it apart.
In any case, glad to hear that you got your gear up and running. |

I have an older Joyo tuner / Isolated power supply on my guitar rig. Works good for quite a few years.
Stopped the buzz I was having.
