Backert Labs Rhythm 1.4 preamplifier: New Stereo Times review on a great line-stage


Stereo Times has just put up my new review on the Backert Labs Rhythm 1.4 preamplifier. This is Backert Labs most recent generation of their ultimate top level model. Bob Backert has always been a brilliant designer and his crew of his son Gary and Andy Tebbe hand build very special preamplifiers. The review will give you all the details about the Rhythm 1.4 performance that made it a total pleasure to review.

Teajay,

Were you able to compare the Backert with the Aric Motherlode II? I’d love to hear your thoughts. 

Great question paullb,

I own both of them, therefore the following comments are based on long term listening in the same system. The Motherload MKII and Rhythm 1.4 are at the apex of the state of the art in tube based line-stages. Both are built/designed by very talented artisan craftsman. 

As I stated in my review great tube preamplifiers completely disappear and totally allow the tubes to be heard along with providing the necessary dynamics/speed of the music by having superlative power supplies. 

Therefore, the difference between the two line-stages is which tubes they use. What do you like better, 6SN7s or 12AU7s? Both tubes are great, but present music somewhat differently. For example which do you like better 2A3s,300bs,211s? All great sounding power tubes but different. Which would give you more synergy in the context of your system and better fit your personal taste? Both preamps are superlative, but different because of the tubes they use.

@teajay  So for those of us who don’t know the differences between the rubes, what are the specific sonic differences between the Rhythm and the Motherload?  It’s not lost on me that the Rhythm costs more than twice the price of the Motherload. 

Hey soix,

Both preamps have none existent noise floors, offer excellent overall dynamics, have great control and extension on the top and bottom frequencies, and high-level transient speed.

Regardless, of the cost difference they are more similar in the above stated areas and then part ways because of the different tubes each one uses. 

 

 

In what ways do they part ways?  That’s really what I was asking. You seem hesitant to describe the critical differences.
