Moving to the UK - Need Transformer

Run it on 230vac if you CAN, it will sound better.

 Agreed!

I would try and get the equipment converted before you leave. It sounds like you're permanently moving there. You'll be happier with the gear converted.  I moved from the US to UK and sold what made sense, converted what I was able to and bought when I arrived. I actually bought a massive hospital grade transformer for a treadmill that the manufacturer, Landis, refused to convert for me.  They said I had to sell it and buy new there. I think it was about $300 so not horrible. What area of the US do you live.  I may have a few things for you as I'm back in the US now but still have a bunch of stuff.

@bhvf We live in Miami right now. Planning on the move for May 2022. The collective wisdom here sounds like the best thing to do is have the ARC pieces converted here. I’ll reach out to ARC customer service and see what they advise. I’ll reach out to DCS customer service to ask them if they can convert the Bartok for me. 
Thanks for all the info and advice. 

I've no idea your living space in Manchester, but have lived and worked in Europe for some years and know first hand flat space limitations.  I moved around Austria and each space was quite studio small compared to what Americans expect.  But then, you may be in a full cottage for that matter.

Your ARC equipment alone is quite physically large and coming in at over 150 lbs. shipping weight if my calculations are correct.  You are accepting that shipping that far does not ensure safe transit.  And what if you need repair on any of the pieces?

I know I'm wandering off the OP question, but why not consider having fun at audio shops in Manchester and assembling a cool compact British system there?

We all think differently, just my two cents.  I could be way off base.  Have fun with the fish and chips and spotted dick.

@celtic66 Thanks for your thoughts…! We’re planning on buying a house outside Manchester…so I’m hoping to create an office/listening room there. The amp and pre amp and DAC all sit on a rolling custom rack that doesn’t take up too much space…but your thoughts are noted…! I’m already nuts for buying what I have…!!
