Hi …
ESD DAMAGE…QUESTION:fire:
This is a “dear” problem within our interest.
I’m not that up to date on the subject other than I’ve heard an ESD damaged RIAA product.
In the picture below you can see how a USB- receiver card arrived to me yesterday,.between two one centimeter thick styrofoam sheets.
Otherwise well packed in a small box with bubbleplastic wrap above and below these styrofoam sheets with the USB-card in between.
It was NOT placed in an anti-static plastic
bag…!!
Could the USB-receiver card have received ESD damage due to this packaging method.
That it lay and “rubbed” a little between the styrofoam sheets…??
The reason for the question is below,.as I wrote to the sender of the USB-card just now…
----------------------------------------
The USB-receiver works…!!
BUT,.it’s a big BUT…
The Energy, the Attack and the Timing etc in the music are not at all at the same level as with the previous USB-receiver card.
The upgrade effect of the new V7-Classic Dual OP- amps is gone.
AND,.to get the same volume with my reference songs, I have to have the volume four to five digits higher…
Example: Instead of volume 25, volume 29 or 30.
I’ve had the same volume on all my previous four new amps I’ve bought from you over the last two years.
AND,.it came between two styrofoam sheets, not in an “anti-static bag”…could it have ESD damage.?
I’ll tell you more later,.my amp is put on a constant playlist to see if it gets better after a few days of break-in/burn-in.
But as it is right now, it plays more Hifi or Sound than Music, if you understand what I mean, I can’t bear to listen for long, it plays boringly.

This above is an abbreviated extract of what I just sent to the sender of the USB-card.
Comments on this are very welcome…
