PASS - comparison X 350 to XA 60.5

JI35,

I do not think there are any changes in the amps at all over the years. If there are, can you confirm what they were? I am quite certain there are not any.

There is zero difference between a new pass amp and an old one. Identical, Any change results in a new model. These posts are misleading.

There is no difference between a pass amp built yesterday or 9 years ago. When a change is made the model changes. If the model has not changed then nothing else has either since the original design.

My comments are based on a conversation with Pass Labs two years ago. I had called to ask about the changes on the rear panel between earlier and later versions of the X250.5 The RCA and XLR connectors are located differently on later models.

I also noticed that the location of the speaker connectors and fuses had changed, and they used a different rear power switch.
