question about training

Hi, thank you for the great work.

I have two questions.

####
python train.py -train_dir your-path-to-npy-dir -m vqvc+ -n 64 -ch 512 -t train_simple_normalize
####

with the above command, can i recover the results you have shown on the demo website?

And also with the same command, only changing the channel 512 to 80, will the result may similar or worsen the quality?
