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?

Couldn't tell you as I've not heard them but I can tell you I prefer tubes especially in preamps. You need them to get things right at the front end of the system; no amount of the best amps and speakers can bring back missing elements in the signal if the preamp doesn't do its job.
@oldschool1948-  When you're ready to try a little experiment, PM me.  I'll send you a nice pair of Amperex 6922s(no strings), to try in your Herron.  Even two out of six, should give you an idea of what's available, if you roll.  btw: Would your Old School 1948, happen to be a Pan?
I re-read my post. Blows away is not accurate. I am passionate with regards to the vtph-a, it is the best I have heard.
