The Raven. I heard the prototype and was able to compare it to the LTA. It was an immediate "no contest." And the final product has a couple more improvements that Don Sachs, Lynn Olson, and the guys at Cinemag used to put on the final touches. This was a great collaboration between some great names in audio, and it shows.
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.
