I have the Topping D90se DAC (the latest) and it is rather good. It is in the neutral camp so I think it would pair well with some warm electronics or speakers. I actually use them with Benchmark AHB2 (which are not warm) but this combo is in the camp of adding nothing to the sound. It is the opposite of my other system so it is a nice change of pace for me.
The D90Se is $899 (or 599, I forgot). Another DAC that is also a great buy at $1350 (on sale now) is the Gustard X26 Pro. This is a warmer DAC and a DAC people should try on home trial before they spend more money. There are 4 filters and NOS/OS mode to tailor the sound.
