I am not technically skilled, but as I have understand its not about the power at all. I have been told that K1000 can be driven with 5-7W p.ch. easily, but must be high quality class A one, however an good T-amp, which TA is, drives them very, very well, imo.
I was listened them closed, but when I have got TA, started used them semi-open, well, slightly less than semi, and the sound was never thin. Its always good to try some things out, especially when you on budget, but still get something different, which may give you more flexibility in use with different genres. And I believe that TA is a good choice. Check Google for many reviews of it Trends Audio TA10.1 - Google Search
