Sim Audio Moon 340i

I'm not sure if this is the correct place to ask this, if not, then perhaps someone could please redirect me.

I have recently had a home demo of a Moon 341i d3px and the 260d transport which were both recommended to me.

They both perform brilliantly in my system and I would like to consider a purchase.

I was not aware of the Sim Audio/Moon brand until now and know very little about the company.

I note that the Moon 341i d3px was released around 2012/13 and the 260d a little later, and so am a bit concerned that they are both "not recent" models.

I would like to purchase these items new and am wondering whether they are likely due for replacement or an update any time soon.

Do Sim Audio keep their models running for a long while as opposed to updating at regular intervals?

If current users who use or have used Sim Audio products have any information or advice on this, I should be very grateful to hear it.

I am based in the UK

Thanks
