I agree I think if you liked the Kef 500 and tube amp get that. We all have our preferences. I wouldn't get that if I had that money to spend but that's just me. Sounds like you know what you like and can tell the difference so chances are if you buy anything without an audition first you might be disappointed. I personally don't like tubes for the reasons mentioned above and most of all for me you can't really leave the amp on all the time. I like my gear on for listening at a moments notice. I don't really do listening sessions and then turn off. If that is the way you work, turn your stereo on and listen then turn it off then tubes are awesome.
Oh and personally I would avoid speakers that are going to need a sub. Personally I have never been able to make a sub work wonderful. If it was me and the Kef 500s didn't do it for me in the bass I'd try and find a model up from that did. Others disagree but that's my .02 on subs.
Do you have to buy source gear as well in the budget?
For reasonably priced cables I think the Grover Huffman cables are really good. I've had a lot of cables and to me these cables sounded good and good enough price that I just quit buying cables and stuck with these.
