I'm a statified Herron owner who gets to hear the seemly top two contenders (the I/O Sig & Lamm) on a regular basis. I never come home after hearing either the Lamm or I/O with preamp envy. I like the no fuss aspect of the Herron's. The Herron's are at their best with current production tubes and are easy on them. IMO, the Herron's are under appreciated in audio land.
