Also too I think the reason why there are a lot of Jolida ads here is Underwood Wally has a strong presence on A'gon. I think him and Audioforce have a lot of Jolida listings. I have not been able to do a comparison of dealer adverts vs. used adverts to confirm. I concur with Response34's and TBromgard's points about Jolida.
I think your nephew will definitely enjoy 1501RC and will have an easy time selling it when he wants to move onto other tube gear. Getting into tubes for me was very infectious. I'm now going from a homemade tube buffer to a tube amp, tube preamp, tube dac. All I need now are those ICs with a 12AU7 tube and I'll be set till they make speaker wires that also use a 12AU7 tube.
