The Blue Circle integrated can be ordered with a $75 sub out as an option, I believe. It has a robust transformer and pretty good level of capacitance for its price. Point to point wired.
When looking at integrateds to use with a sub via rca out you need to know if the preamp inside is passive. That can complicate hooking up a sub this way, but may not rule it out. I know the Creek and the Jolida tube integrateds have passive preamps.
