I'm a reviewer for hometheaterreview.com and just recently had the Backert Labs Rhythm 1.1 preamplifier in for review.
It is a superlative linestage across the board: 1) Very high build quality and parts 2) Overall innovative design 3) And most importantly one of the finest tube based linestages, regardless of price, regarding dynamics-soundstaging-transparency/micro-details and just beautiful tonality/timbres offered in a musical relaxing way. My favorite tube that I used in my process of reviewing were RCA NOS 5814 Black plate triple mica. My review will come out in the next couple of months with much more details regarding this excellent performer
