Thoughts on Overlord 12AX7-HD / ECC803S-HD tubes

Hi everyone

I stumbled onto a listing about Overlord 12AX7-HD tubes but didn't find much info on them.

Here are some videos

When I looked at some information about them the info was vague.

Has anyone heard about these tubes or used them in their systems? IF so what are your thoughts. From looking at these tubes I think they are a dressed up 12AX7s.

Thanks and I honestly have no affiliation with the seller of these tubes or the company that makes them. I'm just curious about them.

The only way to know for sure is to listen to them, of course, but I'm skeptical of tubes that come in fancy packaging and use crystal technology.

The guy selling them has some other nice tubes for sale, though.

$400 can buy a pair of really good 12ax7s with solid, long held reputations. $400 is above my limit for a what the hell let's give them a try purchase.

If they got down to $25 a pair, I'd give them a try.
