And for the M15Pro, here's a unified reply:
1. At present, we have clearly given up the plan of M15Pro. Because several plans originally planned were rejected.
2. The original plan included Plan A, replacing the copper shell + replacing some fever components on the basis of M15. The reason for the rejection was that users felt lack of sincerity.
3. Plan B, Change the AMP to THX AAA. The reason for the rejection is that the power will be much smaller than M15, so it was rejected by the user.
4. Plan C, many people expect to change to the THX amplifier, but if you want to use the THX 788, since the THX 788 is a desktop computer, the output power is more than 2 times larger than the M15. The small change based on the existing M15 cann't accommodate. If there is a major change, What will it be? What are the design goals? To whom? How much does it cost? These have to be re-planned. Even if we do, there are a lot of variables and a long way to go, so we have not final decision now.
So if you just worry about the M15Pro coming soon, then don't be worry because it's gone.
