I too am going to wait before committing to the Version 3 upgrade. I’ve been very happy with Version 2 with the 6SN7 tube upgrade. I’m currently running the MicroZOTL pre with a Simaudio Moon 860v2 SS amp and it is a great combination.
BTW, I agree that LTA is a good company and very open and trustworthy. They have the best Customer Service I’ve experienced with audio firms. 👍🏻
