I have had the e&s for about 6 years and ordered 3 Urei knobs from Harman so it matches my 1620LE. The Urei knobs feel so much better. I also am pretty sure that the pots are Blue Velvets. I do like that with the GSA you can choose RLA, or Urei knobs. Remember that Jerome was building them for GSA before Gary Stewart started making his own. The e&s is a very nice unit.
