You have built two preamplifiers and they both look awesome. Are you looking for a specific sound?
I'm pretty happy with my DHT linestage, but I wanted a good backup. I am planning to rebuild portions of the DHT linestage to fix some things I wasn't happy with (not related to the sound), so it will be out of commission for a little while. I have been curious about using inductive attenuation instead of resistive, so thought I'd give this a try.
I've only listened to it for a few hours, but it is sounding pretty good. I think I still like the DHT linestage a bit better, but this TVC linestage sounds quite nice and will make a good backup while my DHT linestage is offline.
