The best sounding amps I ever had driving the Eros were the Monarchy Audio SE-160 tube/MOSFET monos. The tube amps I tried, including a highly modified Dyna ST-70 and a Music Reference RM-9 Signature did not work that well. I don't think that most tube amps will deal well with the dramatic impedance curve the Eros presents.
I'd look for a good tube/MOSFET hybrid amp like the Monarchy's. I'm now using the NuForce Reference 8 and Reference 9 amps with very good results on other speakers... With a nice tube preamp up front, the NuForce, and other high quality solid-state amps should work well with the Eros. Just make sure the particular amps you select will work well with low impedance, high-capacitance loads. Good Luck.
