I can understand your concern in regard to having to wait so long for your audio equipment to be repaired. Unfortunately, Covid has only made the situation worse.
Especially when you are dealing with a small company (sometimes even a one person operation). I ordered a DNA Starlett headphone amplifier in January of 2022, with an estimated delivery date of November of 2022.
I'm still waiting nearly 18 months later. My Starlett is now scheduled to be delivered in July of this year. Hopefully it will be. The owner of DNA, Donald North has explained to me that Covid has created numerous problems with supply chain issues. In addition to this, there have been many quality control issues with parts not meeting specification, that had to be disregarded.
This only slows the manufacturing process even further.
I know that DNA manufactures world class headphone amplifiers, so I am willing to accept the long manufacture time. It just goes with the territory.
