New streamer needed

- I am looking for a streamer only, as I have a separate Merason Frerot DAC, preamp and power amp

- Roon is not important, Volumio maybe yes

- It's for my main system

- Headphone option not important

- Wifi

- (Needed) budget is part of my question, but preferably <2500. Can be used too

- The Accuphase can be used as a DAC by the streamer, but sounds better with the Merason

I recommend a used Aurrender N100. But any Aurender you can afford. I own two.

If you do not have the upgraded power supply for your DAC, I would also recommend that.

I have heard the N100 against streamers of a lot greater value and besting them. Very natural sounding and detailed. It is very well built and the Conductor app is very well liked and funtional. 

i would avoid the Roon. Unnecessary cost and I don’t think it will be around for the long term.

Also, do not get one with an internal WiFi. They tend to perform very poorly and be unreliable. Just buy a cheap wall wart WiFi extender and plug in next to your system, plug a short Ethernet cable into that.

@stievus if you can stretch it, there are few used Aurender N10 streamers on US Audiomart. 
Another option is Lumin U1 (not the mini). But the UI(user interface) of the Aurender app is significantly more user friendly. 

Thanks for your recommendations, I will look into these. I have the Merason power supply. Perhaps difficult to comment on, but now I am considering selling the Accuphase and replacing it by a streamer like the N100. Will the sound quality be on par with the/a CD transport?

I’m not sure about N100. Not familiar with Accuphase or Merason either.
It took Aurender N200 in my system to level the playing field.
