I believe so. Trying to ignore that I built it, is seems way more transparent than my little Wright 6SN7 pre and more dynamic than the Cary SLP-98. The preamp creates a whole brighter more expansive view into the music. I'm back to a little more hum in one channel but since I've had it quieter I'm assuming some wire drifted closer to something hum producing. Overall, I'm very happy and have begun ordering parts for a final build. You might see what @jmathers has to say. He listened a little bit on two different occasions.
I certainly will look back at those post from @jmathers.
Really excellent work and determination to see it through to the end. I might have been tempted a few times to just chuck the whole thing out the window as my patience isn’t that good.
