Best integrated or power amp -- voltage switchable


I will move back and forth between the US and Europe.

I would rather not use a step up/down transformer or send my amp to the manufacturer to adjust for the different voltage.

The best voltage switchable power amp I've been able to find is the Parasound A23. The best voltage switchable integrated I've been able to find is the Arcam A38.

I would greatly appreciate any suggestions!
Don't know what kind of money you are talking about, but you could check with Jeff Rowland and ask him about his current and older integrateds, and power amps. I suspect there are others too.
Thank you! I will look into the Jeff Rowland Continuum 500.
You could find an e-series Threshold amp with the voltage cartridge that you rotate at the back of the panel to go from 100V, 120V, 220V, & 240V
The Jeff Rowland Continuum 500 looks to be loved by those that own it, but there seems to be a lot of Class-D naysayers.

I'm not sure if I want to spend that much without being able to audition.

I couldn't figure out which Threshold amp to consider.

Any thoughts on the Arcam A38 or the Parasound A23?

Any other amps to consider? Thank you!
