- What thing do you like most/least about it?

Less: Piezo motor with very low efficiency, rapid distortion. 175W RMS power into 8 ohms (aïe!) I suggest replacing the tube by a piezo compression!
Plus: Speakon Connections

- What is your opinion about the value for the price?

Medium. For the same price, it is better!

- Knowing what you know now, would you make the same choice? ...

No. In some cases where prices (Cerwin Vega INT 152 to 200 euros per room!)
PS: I changed the DAP by putting new filter and tube with 1 "Compression
But this is better way!

For beginners, this may suffice.
