Luminous Audio: Are They Still In Business?

Hello: After doing some research, I decided to purchase a passive preamp from Luminous Audio.

I understand there is a customized aspect to tailoring the preamp to individual systems, but 24 hrs after ordering, and sending in multiple messages detailing my particular modifications, (There were no price adjustments for modifications like balanced XLR, better quality resistor, etc. in a drop down menu on eBay) I have heard no response at all. It will cost a bit more and I wanted help in figuring out how to bill for the additional amount. My payments have been deducted from my bank balance or pending. So payment isn't an issue.

Anyway, I also called the Richmond, Va. number and there is nothing but voicemail. The Facebook and Twitter pages haven't been updated, apparently in a year or more.

I do see completed sales within the last month or two. 

Also, many businesses now keep different hours or have scaled-down operations due to COVID.

Maybe I'm just jumping the gun, but being used to ordering various items through Amazon and Newegg, and even most eBay purchases, I get some sort of acknowledgment. eBay has confirmed the order, but nothing acknowledged except that I bought the item.  https://www.ebay.com/itm/130678286565
