> [@Paul](#): > > Sorry about the metering system. It’s about 1% accurate (hardly for “amusement”). The P20 was showing 6.2% distortion when the actual distortion was 7.8. The comment made about amusement meters was not the only comment about them not being accurate. Was told you stated that it would cost too much to make them accurate. > [@Can the P20 meters be calibrated?](https://forum.psaudio.com/t/can-the-p20-meters-be-calibrated/33416/25): > > Elk > Paul has addressed the cost in the past and started the added cost was significant enough that it was not worth it > > If one knows the error and it is consistent, just do the simple math in your head. I wasn’t expecting lab instrument accuracy however over 1.5% error in the reading is more than 1% error as the meter max is 10%. I had several friends over and they all agreed the Surgex units sounded the best and had the most punch. The direct connection to the wall power was 2nd best. This was tested with 2 different pairs of monoblock amps. The other issue I had was the P20 made the transformers in the amps buzz. Maybe I received a defective unit??? --- _[View the full topic](https://forum.psaudio.com/t/anyone-experienced-a-regenerator-making-their-equipment-sound-worse/32889)._
