Active speakers and DAC

Oh thanks, so do you recommend me to go for the A500? They were only an option but due to what I’ve read seems they are a great alternative.

The Buchardt will work with the DAC but it isn't necessary, everything runs through the A500 DAC so it doesn't matter if you connect a $10K DAC or a cheap streamer or preamp, it would sound the same.  I used a Lumin U1 mini which doesn't have a DAC. I didn't keep them, IMO the bass was to boomy and unnatural but the A500 can be EQ'ed. I didn't spend a lot of time trying to get them right I moved on to different speakers. For the price they are pretty good speakers at times I wish I would have spent more time working with them in my room but I had 3 different pairs at once and went with Genelec.  

Only can use if thedac can control volume

I heard the buchardts at axpona last year wasnt impressed at all totally over hype the kef ls 50 meta  wireless is  far better
