Conrad Johnson and Herron comparisons

@jjss49 Ive purchased a rev3, and plan to post my subjective views on the differences soon, complete with internal pics to show any internal differences (if any obvious ones can be noted). Ive sent a few emails to Mr Herron about the upgrade situation, and since that was a no go, I ended up buying an upgraded unit. I was quite happy with the un revised VTSP3a's sound, but curiosity and the upgrade itch got the better of me.
I plan to continue to listen to the units (whilst the one I have on sale is still in my hands) with a wide range of music, using vinyl and digital formats. I find comparisons easier with well mastered CD's. 

@saika2

got it! well just from my experience, in these linestages running several 6922 equivalents, like your herron (4 pcs) and my prem16ls2 (6 pcs), the quality and quietness of the tubes are paramount...

good luck have fun

VTSP 3a runs 3 pairs of 6922's. 1 pair may be for voltage/power rectification, (don't quote me on that last part.

i saved this chat, to respond, now i have a chance.  
from the 3 amps you have been talking about on this forum
herron 3a
cj et 5se
and the vac, dont know much about them.  can some one tell which is the better amp, and what is the quality of each vs the other thank you.....

Just saw this, sorry, I thought the thread was dormant........I personally have not experienced all three of them and hence am not qualified to compare.....some others may have and I look forward to their opinion.

I have owned and operated a Herron VTSP 3a rev 1 and 3 - Im able to say they are both extremely capable, sweet sounding, robustly built, thoughtfully functional preamps.
