Mgmmgm, as you probably have known, all FMA will only shine when used with their own appropriate proprietary cabling. In my earlier days (had my 611 for 19yrs now), I tried the mixing and matching game and only to realize their true potential when used as a system (*all cabling+pre) much later. Yes, wrong cables and/pre could have them sounding somewhat off, but when everything is dialed in properly, to me, they still stood the test of time even against today's elites.
My only complaint of them (611), is that they are prone to thermal shut down when driven hard, due to their compact chasis and lack of fan. Again as we know, system synergy is always crucial in this hobby, just much more so with FMA stuffs.
I also think that although FMA make great amps, true forte is their pre-s. Still.. Given a choice, I'd take 1811 over the impressive looking Telos5000. :)
