Hi,

my pass lab 260.8 monoblocks sound great direct into the wall into two separate dedicated circuits but many like even monoblocks into a power conditioner so contacted pass and was advised best into one circuit not necessarily a power conditioner but that is fine too.  The rationale being ground loops or noise....not hearing that though....thoughts?

cheers

My 2 cents are: good CD Players and amps as this already have inside a power cleaner circuit. External Power Conditioning equip have small limited power tô serve your amp-maybe 1000w or 2000W than the hi voltage power transformer that serve your home, that usually are a 100kWA or more.

At the last HiFi Show that I attended I specifically looked to see what the exhibitors did regarding power amps and power conditioners.
I did not see a single exhibitor who ran his power amps through a power conditioner.
I am sure that says something.

Would you have to purchase a conditioner to try with the amps? If you don't have any noise issues then let it go. And I agree, one circuit prevents any possibility of ground loops. Are the circuits on the same phase of the panel? What level of tweeter hiss do you have at 12 inches distance?

X260.8 user here myself, direct to wall outlet(both amps), which is a dedicated 20 amp circuit fed with 10ga Romex.

sounds great, more filling !

X250.8 here plugged straight into wall
 My engineering friend has the XA600's and he goes straight into the wall.
 I also found that the Furutech GTX-D NCF ( R ) outlet made a really nice difference compared to the cheap contractor grade outlet that was in my house.

X250.8 into a Shunyata Everest 8000.  The amp doesn’t see much below 250 Hz or so due to an XVR-1 crossover.  Never tried straight to the wall tbh.  My 4 subs go straight to the wall.

From a lot of experience one way and the other..
In general:
From wall better oomph, more dynamics, bass a little more woolly sounding (sloppy, thick)
From a conditioner greater detail, clarity and microdynamics, some slight loss of bass 'thunder' but increase in bass tauntness
 
Thus it is a tradeoff (as most tweaks are, in reality*)

*Naturally this is an incendiary statement best left to some other Thread not this one.. LOL

I run my Pass X250.5 straight from the wall outlet bypassing my Furman power conditioner. The power supply in a Pass power amplifier is massively overbuilt to handle whatever hash is on the mains and wants direct access to current without any intervening impedance from a power conditioner.

From what I've read from Nelson Pass he recommended no power conditioner. All great amps should keep the power steady and clean themselves.
