I am very familiar with Thomas, and I watch all of his videos. So please take a minute to read what I have to say regarding this amp.
The Gallion TS120 is made by Doge, AFAIK, it's a collaboration between Thomas and Doge. From Thomas own words, I have to assume and conclude Thomas only worked on the voicing aspect of the amp, most of it is just the work of Doge with their own product.
From what I can read on the website, Thomas isn't to blame for what is being discussed in this thread. The 1st crucial piece is the boss Mr. Liu doesn't like direct sales, and he wants to go back to OEM. You can tell Mr. Liu wants to pull the plug on the direct-sale approach.
The 2nd crucial piece of information is Doge own management (has nothing to do with Thomas) doesn't want the doge10 to compete with Gallion TS120. Both product are from Doge. I have to assume the $3500/$4500 TS120 is better profit for Doge than the $2000 doge10.
You can clearly tell this is Doge's work and decision to maximize profit. The 3rd piece of information is "if the TS120 sale is robust, doge10 MK4 will be kicked out even though it's a better product".
Reading the website gives me the impression that a Doge employee is mad at Doge upper chain doing a business collaboration with Thomas.
