I will recommend to include a DIY Audio Nirvana 8Inch Horn in the mix.
As an owner for many branded speakers (BW, Dyns, Proac, ZU, Duevel, SF, among others), I must say that the Audio Nirvana 8inch Horn is very very good, at a fraction of the price of High end speakers.
Also because the AN 8"inch Horn is very sensitive you do not need to get a high output AMP. Instead the budget can do to the most detailed and music amp.
