I just received my ZDT Jr. a few days ago and wanted to create this thread to share experiences, headphone pairings, tube rolling etc.
I’m mostly using this amp with my ZMF Aeolus and although the tubes a not fully burned in yet I already prefer the ZDT Jr. over my THX AAA 789 for those headphones. The low end is stronger and everything sounds more musical and lively. I’ll post more details as soon as the tubes burn in and I’m more familiar with the sound signature.
I also already have some tubes to roll for the amp. All NOS tubes but for now I’m not sure which other tubes I should try first. I have 1 pair of Mullard ECC89 power tubes and for driver tubes I have Mullard M8100, Siemens 6AK5W, Telefunken 6AK5W and GE JAN 5654.
If anyone else has the same amp and some recommendations on which tubes to roll first I would very much appreciate it.
