Really depends on what sound characteristics you’re looking for. That said, I also have a fully modded DNA 0.5 and I’d do a trial of the Raven without a doubt, but that’s me.
Looking at these specific preamps give me your opinions
I'm building a system and I have an SMC Audio DNA.5 power amp that was built about a year ago so it's up to date on technology although it is still single ended. I have NX-otica and OB subwoofers from GR Research. I am looking for a good preamp. I have a few in mind and would like some opinions. I have listed them below.
TLC-2 GT24 built by SMC Audio
VRE-1c made by SMC Audio
Revelation Raven tube preamp by Spatial Audio
LTA tube preamp
The TLC-2 and Revelation would need to be purchased new the others I might catch them online used.
