jimbennet "Now you know first test was with a FM tuner ads second test with TT arriving 2 hours later a second test. The second test sounded like a different amp yet you are playing games including the first test as valid performance"
In your other Douk thread you wrote after you got the TT that the Douck was better than low level tube preamps. Here’s your post
"Update: My previous review was done with an FM tuner. What a mistake. My new TT arrived 2 hours later. Using the TT the amp is completely different. IMO it does sound as good as lower end rebuilt with better PIO caps and best tubes tube amps. A Scott 222 tube amps is better but not by much. Typical lower end Knight and Lafayette tube amps are a waste of money compared to this Douk amp.
Then in this thread you declared it is better than mid level tube amps.
"Next is a Douk NS-13G class D amplifier. This amp is stunning. Sounds same as a midrange cost tube amp"
You do know that you wrote those don’t you, or do you simply like to try to skirt the issue.
