Echoing what's been said already, the VT130 will have no problem driving the Vistas and will be a great match. Unless you want rock concert volume levels, but then you probably should be looking at other speakers if that's the case. I have EM-ESL's which are pretty similar and drive them with a ARC VSI-60 and have no need for additional power. I previously drove them with Rotel and Parasound solid state amps and Rogue tube amps. Love them with tubes, hate them with solid state.
Martin Logan speakers
Are Martin Logan speakers still considered to be high quality speakers? (I have an opportunity to buy a used pair of Vistas) I have an old Audio Research VT130 amplifier. Would it be a good fit with the Martin Logans? If not, what would be better, but not outrageously expensive?
