Agree with @smodtactical, a direct comparison with the LTA preamp would of been helpful, since it was(is) your tube reference. For somebody looking at the LTA preamp to purchase, your review was lacking in any real help in evaluating preamps.
Review on AricAudio Motherlode MKII preamplifier
The Stereo Times review on the AricAudio Motherlode MKII preamplifier just went live on the website this morning. I have received numerous inquires regarding this review after posting a thread regarding how superlative Aric’s new reference preamplifier in it’s performance across all sonic parameters. The ML MKII will compete with any line-stage, regardless of price, and I purchased it to use it in my different systems. For the details, regarding my conclusions, take a look at the review. I also put it on the Stereo Times list for "2020 Most recommended components of the year".
