I haven’t heard it myself, but in addition to the Pendant, ZMF also just recently started carrying the Cayin HA-300, probably should be on your list of “tube-y” amps to research:
I also know m0n says really good things about the MZ2 and MZ3, but I’m not sure that they fit your preferences here from what I’ve read about them? Still might be worth looking into!
Also, for future reference, this forum has a thread specifically for asking questions about source gear, such as asking for amp and DAC recommendations!
