Backart Labs Rhumba Extreme version 1.4 Linestage Tubed Preamplifier


Looking to upgrade from my current solid state linestage. Many users have recommended the Backart Labs tubed linestage Extreme version. Does anybody currently own this product or have heard this product?  The retail price is $8500.00. Would appreciate any comments that could help me make a purchasing decision.  Thank you.

@pbecker128  Here’s an interesting thread that includes the very experienced and knowledgeable guys who designed it that you might find interesting — I sure did.  It’s impressive the lengths they went to in both the design and choosing the parts they did and why.  It just exudes bespoke quality and end-game preamp level to me.

@pbecker128 I have nit heard the highly respected Backert preamp.  However, I currently have the Aric Audio Motherlode XL in my refernce system.  That is one helluva clean sounding, spacious delicate preamp with beautiful tone colors and a touch ot tube sparkle.  I have run it prevously with the Pass Labs 250.5 amplifier with great results.  

I own a Rhumba Extreme 1.3 and ran it for a few years with a Pass XA30.8 which I still have. These fed into a pair of Audio Note AN-K spe speakers which some would argue are too small for 12x26 room. The room is sectioned with a sofa and I sit off center to the right. It had been a great combination but I wanted to try a tube amp without breaking the bank while still holding on to the Pass. So Aric and I went back and forth on a custom build for an EL-84 two channel amp which is configured as a single-ended pentode. What I was looking for, and what I found was more detail in the midrange at lower volume levels. I found levels would roll off more than I liked with the Pass. Based on my listening experiences, assuming you're keeping the Pass would be to go with Aric's preamp.

Backert seems a solid chase.  I’ve no experience with them, however would agree with previous poster regarding power conditioning.  For years ran Furman, then substantially upgraded to Decware power conditioner.  Convinced!  Now Puritan Labs 156 and really done.

Dirty power abounds and is mostly not accounted for sonically until it’s no longer there.  Everything improves when done correctly.  Best of luck.  Ciao
