My first preamp was a McCormick Micro Line Drive paired with its companion Micro series amp. The Line Drive was capable of both passive and active operation with the passive option receiving all the positive reviews. In fact, if I remember correctly, all the reviews I read were careful to stipulate that the enthusiastic recommendation pertained to the passive option only. So, being new to all this, I went passive and never gave it another thought. Nearly a year went by, and I can't recall what made me do it - probably a disappointing cd, but I switched to active. I don't doubt that I lost all the cherished nuances that the reviewers cited, but who cares - I was dancing. Larry is spot-on, and as Tvad pointed out on another thread: "Lrsky has excellent sensibilities when it comes to sound and matching, so I would give his recommendations (whatever they may be) proper consideration"
