I haven’t heard these but personally wouldn’t use tubes in a phono pre-amp as a pre-requisite as the risk of extra noise is considerable. Instead, use tubes in your main pre-amp and roll those as you like. This will keep system noice quiter and provide consistency across phono and DAC in the main system.
I left my tube phone pre--amp (Project DS Tube - just above entry level)
You need to venture beyond entry level before making such pronouncements. My Herron VTPH-2A tubed phono stage is dead quiet.
