Yes because mine doesn't make that noise in Bill's, Richards (not on this forum), Paul's, Lukasz's, Greg's, Robs, and many others. It does make in yours. A lot.

Should be clarified as Justin's Lampi, first big 7 ever built, with zero upgrades. You should take your Lampi to Bill's, who is not far from you and do a Lampi vs Lampi thread as a precursor.

Have you damped the chassis? I expect not but the cover does ring and I would damp it if I owned one.

You will need tubes that are microphonic to some extent for it to show Norman. In the first GG the Psvane 101D was dead quiet. Then I think I tried the Cunningham CX-345 in it and it went nuts. Tried it in mine and it was fine.

Actually PX4 is mildly microphonic in mine if you tap the tube directly.

It is very strange and whilst Ked thinks it is my preamp I have had other valve DACs in it with no issue.

He'd learn a lot more than I would coming here with his GG. Could always plumb in the Air Tight passive to rule out my preamp.

But seriously, he'd hear my Duettas in the best state they have ever been in.

Arshad, Ked rightly called out my previous room in London for being harsh, reflective, poor boomy bass, zero imaging etc despite my pleas that the core tone was good.
His diagnosis of my room issues was spot on, and he lent me some Mooks Giants to try out.
And they contributed a lot to making the sound more palatable, textured and inviting, enhancing warmth and extension in the upper bass especially.
I bought the set from him, and whether I used them under my big 85kg balanced transformer or my smaller cdp, they were 100% beneficial. Ked still didn't rate my sound, and felt the Giants weren't ideally suited under a mid size component like my Eera, but the positive effects couldn't be denied.
A slam dunk impvt, and I invited the skepticism of Ron Resnick and other nay sayers when I announced my intention to Mook out my whole system, Giants under bpt and monos, Ultras under cdp and preamp.
Had I stayed in that room, I'd have put aside £00000s to Mook up fully.

Fast fwd 18 months, I'm now in my new room, and it's instantly 1000% better than my old space, and that's before I've installed the dedicated power grid or any other tweaks, just power out of domestic sockets into £0.99 off the shelf power cords.
I install the Giants under my cdp as a first tweak, and things are plain wrong. Bass is increased as in London, but now in all the wrong ways, muddy, unfocused, bloated. Replace them with a set of Symposium hard footers and things are motoring again.
Power grid goes in with balanced transformer, Symposium footers good, back to Giants, and if anything it's worse.
Ked informs me it must be "wrong" to use the Giants this way, only Ultras to be used under mid size components. Well, why were the Giants great under the "wrong" component in London? And putting the Giants under the transformer ("correct" here with the unit being oversized) was similarly anti climactic.
Cue disagreement w Ked.
So out they go, and in go the Stacores, first under transformer, then cdp, both with 100% stellar results.

Fast fwd to recently where I've been installing SR Black fuses in my gear, all great except for some ambiguity with new fuses in preamp. There are ELEVEN here, so some likelihood of needing longer burn in, but for the first time since I started tweaking out with Stacores, Sablon Elite pwr cords and these fuses, some move backwards in overall SQ with bass a little one note and slow.
I try my luck putting the Giants under my preamp psu, and things streamline in the bass quite a bit, and I resolve to at least use this one set of Giants in the system.
Note, again if one is to take Ked's view, the Giants are "wrong" in this application, with the psu even smaller than the cdp.
---
Things still not quite right however, so I try a couple of things, first correct the reverse phase on my spkr cbls (NAT amps designed to wire to spkrs out of phase, reversing + and - on the spkr cbl terminations). This is against the design ethos of the amps, but for the first time ever it sounds right with "correct" polarity direction.
And then I again remove the Mooks.
And now EVERYTHING snaps into place. Bass bloat, unwanted smearing etc is gone.
---
And so my on/off/on love affair with Mooks is definitely off again.
And all of this has cemented in my mind that Mooks enhance resonance frequency bands in the upper bass/lower mids. Where an acoustic is harsh and hollowed out as in my old apartment, they are a boon, exaggerating a warmth that is desirable but probably not accurate or on the recording.
In a more forgiving room where bass is not challenging, and there is no harshness to start, the Mooks IMHO act as a coloring device, here totally undesirable.
The Stacores on the other hand, don't draw attention to any one frequency, being even handed across the spectrum, and just open up so much of the musical canvas w'out drawing attention to themselves.
I realise my view might be a minority one, but I feel my experience of living with the Mooks over time in two vastly different environments gives me more than enough to work out what they do, and whether they're for me.
And they're undoubtedly not.

I feel it has to do with imp matching to the next device
In my case I use my Msb as a preamp to resolve this and it’s gone.
