Help With New Preamp Decision


Like most of us, I am constantly in the process of slowly (as funds allow) upgrading my system to what most would consider "mid fi" or low end "hi fi". I have been reading a lot lately on the subject of SQ upgrades, and what comes up frequently is that the preamplifier might be the foundation of moving to the next level as I upgrade.

True or not, that is the direction I have decided to go....my virtual system is listed. And yes I know I need to upgrade other components as well, so I'd like to keep this on the idea of a preamp.

In doing a LOT of research, I've come across several preamps that I am most interested in and would appreciate some ideas/thoughts/input/recommendations. I want fully balanced XLR with RCA inputs and outputs,  be tube based, and I have no need or desire for a phone input. Max budget is $6,000.....or just a few shekels more.

(1) Aric Audio Motherlode XL $6,125 - Incredible reviews, Aric has a phenomenal reputation, and seems to be an all around great builder in this field - https://aricaudio.com/products.php?product=MLXL

(2) Backert Labs Rhumba 1.4 $5,000 - I have this lower on my wish list, as it is Backert's entry level preamp, what I'd really like is the Rhumba Extreme....but no way I can justify the $8,500 price. And finding a used Rhumba Extreme 1.3 has proved impossible, though I'm not opposed to it. 

(3) Don Sachs and Lynn Olson new Raven (Revolution) preamp $5,000 - His reputation alone makes this preamp important, and he is an all around great and giving guy of his time. I've communicated several times with Don, and he flat out tells me this is the best preamp he has ever designed by far and is a "cost no object" project. I think that production starts Jan/Feb this year (being built by Spatial Audio Labs) 

 

(4) Atma-Sphere MP3 Mk 3.3 $5,650 - Venerable favorite, it's a well known and well reviewed product http://www.atma-sphere.com/en/mp-3.html

(5) Linear Tube Audio MicorZOTL $5,750 with balanced inputs and Level 2, see this well reviewed and well thought of brand a lot  

 

Thank you in advance for your input

You’ve got some excellent contenders but really depends on what improvements/sound characteristics you’re looking for as many of them sound very different, so personal taste is absolutely key.

I think he was comparing the MicroZOTL to the Rhumba 1.1, but that was several years ago.  I’d imagine the Rhumba Extreme is quite a bit more expensive, no?  I think he may have moved on to another pre from Aric or something. 

Keep it in the back of your mind that you can do an in-home trial of the LTA MicroZOTL.  Terry London slightly preferred it to the Rhumba so that could be interesting.  Looking forward to your thoughts. 

Excellent info — thanks for that! Given what you’ve said I’d be looking squarely at the MP3 because it’s fully balanced. I think the LTA would be next followed by the Backert (Terry London reviewed both a marginally preferred the LTA), but I don’t think either is fully balanced if that’s really a thing for you. Sachs sounds great but I’m not familiar with it and not sure if it’s fully balanced either — I know his prior preamps were single ended only, not that that means anything. My guess is it’d be on the warmer side versus the other three. To me, the MP3 ticks all your boxes, FWIW.  I would also mention that the LTA also happens to be a top-flight headphone amp if that’s at all a consideration.

As a dark-horse option, here’s an ARC Ref5SE that’d be well worth considering and is also obviously fully balanced…

I believe all of the options I posted originally are fully balanced XLR, it is an option on the MicroZOTL

I would double check that. Last I looked you don’t get fully balanced in Backert preamps til you get above the Rhumba, but I could be wrong and maybe something changed. With the LTA you can get balanced inputs with the upgraded transformer, but I don’t think it’s fully balanced from input to output. Again, I could be wrong but definitely worth checking into.

As an aside, if you don’t already know I’d check if your amps are fully balanced from input to output. If not then having a fully-balanced preamp is not as big of a deal because it gets converted in the amp to single ended anyway. If your amps are not fully balanced then it opens up more options on the preamp end. Just something to check just in case.

Someone above mentioned the yellow board was the old board so perhaps the brown board is the new one?
