I upgraded from Zensor 1's to Zensor3's(upgraded again to Dynaudio)& was driving them with tubes,the sound was fantastic!IMO the ULTIMATE amp for todays multi source system is the amp I now have,the iFi Audio "Retro Stereo 50".The amp alone is around $1500.00(you may find a deal if you look hard enough) & it's worth EVERY penny & then some!Google it & read the reviews & yes they are ALL dead on.The EL84 tube is wonderfully musical & organic,those Philips guys really nailed it when they designed this tube.The "Stereo 50"is a true Swiss Army Knife of an amp & can drive EVERY source you have now & are likely to have in the future.
If that's way over budget I would go with a good tube integrated amp & outboard DAC.I can make more recommendations with a budget...
