On tip on Audio gear:

Ignore all the fluffy words just look at the specs. I use an affordable TPA32xx Class D module with a good meanwell power supply and I (professional audio engineer) can't hear any difference to e.g. the stuff Neumann put into my active KH120 monitors.

I don't think some random hifi shop is going to outspec the best class D module Texas Instruments or Analog Devices can come up with. But sure, if fooling yourself with Hifi is your hobby, proceed.
