Backert Rhumba 1.3 OR Modwright LS 100 ?

I have heard the Rhumba and was very impressed. I own the Rhythm 1.3 and it’s the best preamp I’ve owned to date. Previous preamps I’ve had are: Vinnie Rossi LIO DHT, Audible Illusions Modulus and LTA MicroZOTL Preamp Which I still have in a second system.

How does the Rhumba compare to the microZOTL in sound.

Which one has more weight and warmth?

@lancelock ,

Which tubes do you use in the Rhythm?

@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.
