Pianoteq makes me spend money

I think this is true of fine acoustic instruments as well, in principle , but since I installed Pianoteq a couple of months ago, I find I keep spending money. The software is great, but the set up I was trying to use it with, it became gradually apparent, was just not really good enough. First I bought a much better controller, then some somewhat better powered speakers, then a slightly better audio interface, then new cables because there was always this hum. And now I've sprung for better quality speakers, a better audio interface, and xlr cables. I didn't really believe there would be that much difference, but there is. So anyone thinking about upgrading their set up to use with pianoteq, take my advice. Don't skimp. Spend the money to get a good controller (I bought a Kawai VPC1), and get at least decent quality components across the board. The sound produced by the software is very good, but if you use cheap equipment, the results will not match the software in quality.
