Member Terry London reviewed both the Rhumba and the LTA MicroZOTL and slightly preferred the LTA. Just another option. I believe LTA gives a 14-day trial FWIW. Both are great and I don’t think you could go wrong with either, but the LTA also happens to be an outstanding headphone amp if that matters. Best of luck.
Backert Labs Rhumba 1.3 vs Extreme
I am looking for a new preamp. I was curious about the preamp from Backert Labs. I saw some good reviews on them and they peaked my interest. My experience with tubes are limited, but I do have tube headphone amp- McIntosh MHA200. When listening to headphones, I always come back to MHA200 over SS amp. So I know I like tube sounds. Long ago I had Schiit Freya which was the only tube pre I had. I do not like veiled and thick sound sometimes I hear from tube gear. I prefer clarity / open / spacious sound with a hint of softness. I think the Rhumba can deliver the sound I am looking for, but just wondering if anyone has experienced the two models and share extra money on the extreme version is well justified. I will be hooking up the pre with Pass X250.8. Also I'd appreciate if you can comment on quietness of the preamp. Do you hear any noise when no music is playing?
