Sound of Pass Labs xono preamp in 2 versions

Does the Pass Labs Xono phono preamp in the version with the dual matching chasis sound the same as the older model version with the black colored power supply chasis? There's quite a difference in price and I'm wondering do the two versions use the same parts in their power supply? Thanks

Lornoah, I can't answer for the Xono, but the issue is the same for the Pass preamps. I the case of the preamps I spoke to Wayne at Pass Labs (I have the X1 with the smaller chassis PS). Wayne told me there is no performance or sound quality difference between the two style supplies.

The same PS is used for the Xono, but as this is a much higher gain signal amplifier I can't say if any slight variations in either style would be discernable.

I spoke with Pass this morning.

Curious, did they also tell you that there is no sonic difference between the two styles of PS?
