My 1st Tube Equipment Experience


I just purchased a used Herron Audio VTSP-3A(r02) tube preamp, as a replacement for a NAD M12.  I paired the M12 with a NAD M22 v2.  My first impressions are the M12 has more detail, the VTSP is much warmer, which is what I wanted.  The VTSP sound is definitely different.  And while it lacks the M12 detail, I do like it.  

With the M12, my speakers were dead silent when music was not playing.  With the VTSP, I hear a slight hiss when I put my ear very near a speaker.  With the M12, I used XLR from the M12 to the M22; XLR from my Parasound JC3 jr; and RCA from my Liberty DAC.  With the VTSP, everything now is RCA.

Is a little hiss common when using a tube preamp and SS power amp with RCA cables?

It's normal enough to have louder digital. As long as your vinyl sounds good, don't get hung up on the difference.
+1 really good advice!
@atmasphere I'm also wondering how much better a Herron VTPH-2H would sound than my Parasound JC3 junior :)
I finally purchased a Herron VTPH-2A. As it say's on Keith's site, "Immediately you know!"  As recommended in the manual, I started listening without loading plugs.  Paired with my Herron VTSP-3A(r02) pre amp, out of the box, everything is better than the JC3jr, but, I wasn't blown away by the sound.  After a few days, I tried a couple of different loading plugs.  When I installed the 500 plug, the difference in SQ was everything I could hope for.  The sound is rich and full, with much better imaging, sound stage, and definition. 

I have a Technics SL1200G w/ Ortofon Quintet Black cartridge. For the last several days, I've been listening to my old Marvin Gaye, Maze, War, etc., albums that I've had for over 40 years and have played many times on other TT/system setups.  It's hard to put into words how much better they sound.  I certainly expected improvement. I had no idea how much better it would be.  I am one happy camper!

Congrats. I've heard so much about the Herron but it's expensive and I'm not sure it would beat my modded Croft. 
Expensive is relative.  Having said that, I felt the same way.  I was fortunate enough to find a used mint condition one at a very good price.
