LTA microZOTL or Backert Labs Rhumba Extreme 1.3?


Hi everyone,

It’s that time..where I got the baaad itch to upgrade. Currently using EAR Yoshino 868PL into Pass Labs XA30.8 amp.

I love the EAR preamp..absolutely nothing wrong with it. Just wondering about the LTA or the Backert Labs preamp and how they are, if anyone has experience with both (long shot, thought I’ll ask)?

Should I somehow let go of the itch and stick with my EAR preamp? Not looking to change my Pass Labs amp.

 

Thanks in advance.

@benzman - not sure which version of the microzotl pre you had, but mine has - 15db and - 30db gain adjustments. Sweet spot for me is the 15db gain setting. With that I can bring the volume up o 50 out of 99 no problem. I sit about 7 ft away from the speakers and listen at about 55 to 65 db. 

@panerai557 15db is still alot of gain, depending on the amp and 30 is ton of gain. Most Preamps are 11-12 max. 

 

Personally I think the Backert is the better design over the LTA, should have sprung for that.

@jc51373 Curious why you would say that.  Do you know the LTA is a David Berning ZOTL design?  David Berning designs/builds some of the most incredible bespoke (and expensive) equipment in the biz.

Well for starters I've heard LTA...But mainly because of Backerts approach to the power supply which is everything in hifi. 

@jc51373 Well, the power supply is certainly important but definitely not “everything” — the overall circuit design and output stage are also critical, and the LTA uses Berning’s patented circuit design and a relatively rare OTL output stage.  So lotsa variables here and saying one overall design is superior is not so cut and dried IMHO.  I’d also note the Rhumba Extreme 1.3 was 30%, or almost $2000, more expensive than the most expensive upgraded version of the LTA.
