    Guys - several mini-reviews have appeared here in the "Logistics" thread. If it's OK with everybody we are going to copy/paste them into the Backert Labs Rhumba Preamp thread, so that people looking for reviews don't miss them. Thanks.

    I should say that this is the first piece of tube equipment I've had in one of my systems for years. i wonder whether a lot of the difference I' hearing is the difference between tube and SS?.

    UH...does a bear crap in the woods ? Yeeeah !!

    Moose68Bash took delivery last Wed. so later this week he will send the unit to Backert Labs here in Delaware. We will run a final check, then it will be off to nooshinjohn in sunny California. Then to its final destination, breal74 in Washington.

    We would like to thank breal74, not only for purchasing this unit, but also for agreeing to let nooshinjohn be the party who delivers it to him. Very helpful for shipping efficiency and cost. If the unit had to re-visit the East Coast before delivery, it would have meant 3 cross-country shipments.

    Andy,

    It's fine with me that you "copy/paste" my comments above into the more appropriate thread. When I started writing the post, I didn't really intend to say as much as I did.

    Please let me know the address to which you want me to send the Rhumba. I'll ship it off to you on Thursday, if that is all right.

    In spite of my interest to the contrary, I SHALL ship it back to you! :) It's been a great experience, and I am grateful to have had the opportunity to audition the Rhumba 1.1.

Power source for all components: Silver Circle Audio Pure Power One with dedicated 20 amp circuit to main panel.

Power for each component from dedicated 20 amp circuit to main panel, except Innuos Statement powered from Silver Circle Audio Pure Power One.

    Cooties make it sound more lively and transparent.

    As long as they are audiophile grade cooties I will let it slide. But I am sure that you use nothing but the best! Maybe I could ask Jena Labs if they could give them a cryo bath for me?

    Since we don’t know where we are going we have to stick together in case someone gets there….Ken Kesey.

    It is on a truck for delivery today. I am busy with work until Saturday afternoon, but then it's on!

    John was nice enough to give me a call and let me know that he cleaned all of his DNA off of the preamp before he put it in the box. I suspect that it was more for his protection than to be nice though.

    I will keep you posted Tony.

    That John...always looking to cover his rear end.

    Cool man, just looking for further thoughts from you. I'll wait.....which means a few Cannoli's will have to meet their doom in the meantime. ;)

    Good news is that it is in the system, but.... now it has a low level hiss and a light pop about three times a second at constant intervals when there was none the first time I had it during the preamp tour.

    I checked all of my connections and also now have the preamp hooked up to the amp without anything else plugged into the Rhumba. The level of hiss and pops stay constant at all volumes and get drowned out with higher volumes. Also, the bass slam is not as dramatic on the same tracks, even after ample warm up time.

    Any thoughts on what could have changed since the last time I had it?
    Could it be the tubes?

    Thanks for the help gents,

    Brian

    Hissing and popping in one channel or both?

    It did not exhibit this in my rig either. Was there any damage to the packaging?

    Everything looked good and there was no visible damage to the packaging.

    I switched from my ZenWave RCA's to a pair of Kimber Hero's and the problem still persists. Also, the amp and preamp are on separate 20 amp outlets.

    We will need to speak with you to see if we can figure out the issue, and if not, we will need to look at the unit. Not likely to be the tubes. We will handle this offline and report back.

    Maybe after being shipped 47 times in a row it has decided to protest??

    I just talked to Andy at Backert, on a Sunday at that, and he is getting ahold of Bob to help diagnose the problem.

    I have to say that Backert Labs is one heck of a company that bends over backwards for there customers!

    I will keep you posted.

    They are indeed, work it out and let us know when things are back on track. Still want to hear more about the sound from you when everything is back up to snuff.
