    Can you ground your Ruby to your rack with a small thin wire just for static charge?

    I'm not sure what the purpose of doing that would be.

    It's in my sentence at the end.

    Your pops seem to happen after a while of playing a CD. Static build up somehow...that's what I was thinking of. Just like a TT can develop it.

    Your rack is metal isn't it?

    Have you read the ads for static brushes for TTs that ground to your rack or plate screws on an outlet? I would think you have by now.

    I'm just trying to figure out why you have this problem and giving a possible solution. ;)

    A big bag o' clipleads would have made a great stocking stuffer...

    I see what you mean now. So, I was describing the noises as "static pops" because that description most accurately fit what I was hearing. However, I'm unsure if the noises are actually being caused by a buildup of static electricity.

    In general terms, I've never experienced an issue with static electricity in my place like I have in some homes. My parent's house is especially bad in the winter, when you can sometimes see the electricity arc from your finger to what you are about to touch, like a metal doorknob.

    I hooked the Ampino preamp up to a different power amp tonight and played three CDs without any pop noises at all.

    The highly intermittent nature of this problem makes it very tedious and difficult to troubleshoot.

    I don't know if it's static elec. either.

    What you have going on there is a true gremlin. It comes at very different times with different things.

    Now the amps seem to be the reason it happened but I thought the amps were confirmed to be ok before. I also HATE electrical issues.

    I hope you find the culprit soon or it leaves your system for good. ;)

    I've been using the Ampino Preamp hooked up to a Bryston ST 3B for the last several weeks, and I've experienced no static pops whatsoever. Everything has been sounding fantastic, and the Bryston seems to have great synergy with the 703s.

    Perhaps the Bryston has some sort of "protection" in it to prevent "stray DC" from manifesting as unwanted static pops? Whereas the Ampino monoblocks have no "protection circuitry" or something of that nature? I'm honestly not sure.

    It's slightly disconcerting that the issue seems to present itself when using the three pieces as a set, as they are intended. However, it's very possible they would work flawlessly in someone else's setup.

    Sorry to hear the gremlins left your stereo system when you separated the Dayens. That's crazy. Dayens won't like that.

    I'm shaking my head in disgust that you can't use the Dayens as a set anymore.

    I hope you get a solution of some kind now that you have determined it's the 3 pieces together that cause those problems.

    I'll bet you're antsy about picking up those beautiful PMCs after work!

    I would be! :p

    No joke right?^^

    But maybe someone else would benefit from the Dayens as a set and you could get a killer pre to go with your new reference system.

    I already have a killer Backert pre, I could spend the money on worthwhile upgrades like cable risers and shakti stones.

    "pop" protection is generally a capacitor -- maybe an RC or LRC network.

    Well according to Dayens, "Our Monos have input capacitors (they are capacitor coupled) so if there is any DC coming from the preamp (which would be there from the source) it will be filtered in the input stage of the amp."

    Yup -- there are, shall we say, conflicting opinions about whether capacitors (in the signal path) are a good thing or a bad thing. Certainly in the 1970s, capacitors were "out", and so-called DC (direct coupled -- not direct current) components were all the range.

    The problem with direct coupled components, of course, is that they're direct coupled. For example, if one has a source component with a little DC offset, a direct-coupled amplifier can dutifully pass and, in many cases, even amplify that DC... right along to one's loudspeakers. A good does of high-ish voltage DC can cook a loudspeaker driver (usually woofer) voice coil pretty quicly. This can be rather a bigger deal than a pop or click. :(

    As a vacuum tube guy, I am more or less* stuck with capacitors (or transformers) between stages to block plate DC voltage :) I'm OK with that.

    Fortunately, most vacuum tube components couple their power amplifier stages to loudspeakers using transformers. DC cannot pass through a transformer (although an autofomer can pass DC). :|

    * It is possible to make direct coupled vacuum tube circuitry; is it worth the effort? Opinions and experiences differ.

    Well, we originally thought that the issue was being caused by the always-on phono preamp that was connected to the Ampino Preamp. But now, the issue seems to be related to the three pieces working as a set.

    I'm not sure where to go from here other than abstaining from using the three as a set.

    That is the best solution.

    Like the old Henny Youngman routine.
    Patient: "Doctor, it hurts when I do this." (patient flaps his wrist)
    Doctor: "Don't do that."

    This is probably part of the reason that medical care was much less expensive in those days. :|

    Anyone wanna buy a Dayens Ampino Preamp and Monoblocks combo? Mint condition. I'll sell them for a nice price.

    I’m sorry but I would get that warranty claim done. You already started the complaint before the warranty expiration so they should honor it. Let’s see what Verty says about that?

    I'm not sure that there's anything finite enough to make an actual "warranty claim", but I've reached out to Zoran at Dayens to discuss next steps.

    Perhaps sending all three pieces back to Verty, having them make the preamp capacitor coupled, and then all three units getting a clean bill of health and sent back would be the best option at this point.

    I'm the 667th view.

    I had to change that number I saw on the main page of "recent discussions". ;) :D

    It's been a few days and still no response from Dayens unfortunately.

    Wow. That’s not good.
    Any other recourse with the dealer Verty?

    I will give them a few more days and then re-send the email and copy Verty.
