I don't know everyone can agree on a best, but I find Parasound are an excellent gauge of great price/performance.
I find they tend to be slightly warm, robust, and neutral. A number of Class D designs sound the same to my ears, so it seems they are reaching towards a very similar, uncolored, powerful middle.
