Are all R2R dacs slow and soft?


I've tried a few.
Border Patrol, Sonnet, MHDT, Mojo, and a few others I can't recall. 
They all seem to have a slow, soft rolled off sound that lacked detail. The Mojo being the exception, but was still on the softer side. 

I'm now interested hearing the LTA Aero and the May Audio Spring. 
If anyone is familiar with these 2, is it more of the same, or do either one of these stand out from the rest of the crowd?

The reason I'm looking around is I have a PS Audio DirectStream MK2 with the Airlens, and it's very nice and super detailed, but on some recordings, it can be pretty unforgiving and bright. I'm looking to take the edge of without the sound turning soft and mushy, and lacking detail.

I have a Laiv Harmony DAC and it is crisp, precise and presents an accurate reproduction of music I know very well. I would not use the terminology of either soft or slow to describe it, but I am uncertain what you mean by that also, perhaps. But those words do not come to mind for me when I use that R2R DAC. It was well under 5K and will jump up about a hundred in two days.

I also have the PS Audio Direct Stream DAC Mark II.

Can you please post some of the tracks that are unforgiving and bright? I would like to see if I have the same experience as you with those tracks.
