For me tubes are a must in a hi end system.
I have the DI-20, the R8 DAC and the M1 preamp connected to the Line Magnetic LM-518IA 300B integrated, used as power amp. To me, the latest sounds much nicer than my well regarded Class D power amp. More body, more tangibility, better tone and mids to die for. Much more like real music.
My system sounds much better, for me, than a few +100k systems I've heard, all Solid State.
If I had to choose, I would take the Vacuum HE if the rest of the system is SS. If your power amp has tubes, I would go for the regular HE-1 preamp. I think the result mixing SS gear with tubes is great.
