Interesting
I have been experimenting with a DHT preamp volume control for the upper midrange lower trouble with very Impressive results imho , so thanks for the feedback , I am trying DHT EML l 20b single valve transformer volume control pre, the 20b is known to have very low distortion and massive headroom and voltage swings , interested in trying others that don’t have small signal valves eg 12ax7 etc
Yes I am aware of the EML 20b, like the AVVT 20b, though never heard it, but have been interested. More from an amp point of view but even more interested now that you mention the use in a pre.
