@mdrone I think member Teajay reviewed both and slightly preferred the LTA pre, so maybe you can look up his reviews and get more info.  Might’ve been in Stereo Times but not sure. 

I am a huge LTA fan and love my MicroZOTL Preamp. I did recently purchase a Backert Rhythm 1.3 for a second system. The Rhythm is clearly superior to the MZ Pre but at twice the price. I wish I could comment on the Rhumba but I have never heard them side by side. The MZ Pre is no slouch and it’s not going anywhere.

i use NOS 12SN7’s with adapters. This is compatible with the 12AU7 it comes with. The 12SN7’s say Mullard on them and I didn’t know Mullard ever made any 12SN7’s. 

@lancelock In what areas is the Rhythm better than the LTA? I have an MZ2 with upgraded LPS sitting in a box I haven’t gotten to listen to yet, so would be interesting to hear your thoughts before I finally get it up and running just for frame of reference. Never heard a negative word mentioned about any Backert products, which to me puts them among the audio elite.  Also, did you do any tube rolling with the MicroZOTL and if so do you have any favorites?  I tend to prefer neutrality and detail/soundstage but with still some natural-sounding flesh on the bones.  Thanks for any thoughts.

The Rhythm 1.3 has a fuller sound stage and an even more refined, realistic image. It really shows you why a good preamp is important and don’t get me wrong because the MZ preamp is a killer pre and same with the MZ2. Don’t forget the Rhythm is in the $10K range.

The LTA pre’s do respond well to tube rolling. I’m using all NOS tubes. Currently Ken Rad 6SN7 and NOS Brimar 12AU7.
