Atma Sphere MP-1 and MP-3. I prefer Atma Sphere gear over any other tube manufacturer including Yoshino, Mcintosh, Jadis, Audio Note etc. I live in France. We have many great tube manufacturers here in Europe. However, I ended up purchasing american product. 
McIntosh C2300 before they included a DAC. Then you can have the flexibility to include a DAC of up your choice. BTW some amprex medical grade tubes and you’ll be in heaven.
