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.

@gregjacob I replaced the 12AT7s with Telefunken ECC801s. I replaced the 12SN7s with CBS/Hytron VT-231 per a recommendation from Brent Jessee. If you use 6SN7s as a replacement, you just have to slide the internal switch in the pre to 6V. The tubes were not inexpensive, but well worth it in my opinion. The difference to me was amazing.

cbrez   Thanks for the tube suggestions!  I'll check in with Brent.  Of the tube swaps, which set do you feel made the most audible improvement?   I might try one set, then add changes from there...  Thanks.

@gregjacob I'm using the same Telefunken ECC801S.  They are the most detailed and best sounding in my system. A friend thought they were too bright in his system. The Siemens ECC801S are very good, but a hair less detailed. A fair bit less expensive, though.  The Brimar Yellow T are nice and warmer sounding if your system is already on the bright side. 

I own the PrimaLuna EVO 400’preamp. Very pleased with it. Very quiet and great sound stage. It’s a dual mono design and right at 60 lbs. A reliable preamp.
