No - I only stumbled across AssetUpnp because SpinalTap mentioned it and when I had a quick look at the Illustrate site it seemed to offer many features like Sooloos (which I use) and Roon (of which I am very ignorant but note that many people whose views I respect do use).

Because I have never paid anything like as much as Roon’s price for a piece of software of any kind I have so far been highly resistant to trying Roon but thought I should ask the forum whether new things such as AssetUpnp are providing similar functionality at a much better price.

I would not want to pay $500 for functionality I could get, at least mostly, for a fraction of Roon’s price and find within a short time I had blundered as I did with TiVo and to some extent Sooloos. I thought Tivo was brilliant and Sooloos does all I want (well, with some updating) and both are now unsupported (forget Virgin’s Tivo - I can’t get cable even if I wanted it).

My question has led to stout (even defensive) support for Roon but little insight into AssetUpnp. I would like to thank all for the trouble taken over responses but it looks like I will have to research AssetUpnp myself and see how it compares with Sooloos, which is what I would like to find a successor for.

In this context, I am delighted with the work done by Koputai which shows that modest fiddling about can give my C10s life after Sooloos (especially if I overcome my lifetime reluctance to pay through the nose for software and buy Roon).
