First of all I have to say I am completely amazed by these speakers. Mine are stock save Crites xovers (which did indeed transform them). I'll be damned if I don't think they're better than K-horns. Flame away. Do the K-horns have a tractrix mid horn? The fortes seem to have less harshness (almost none) and the bass is much tighter. Admittedly I had the K-horns almost a year ago and had only one good corner - I know that means I did not get the bass performance I should have. Anyway that is not really here nor there. These things are great, not just for the money but in absolute terms, and I've owned numerous speakers in the $5-$10K range.
Current system is an Audio Note DAC 3.1 (built by me), custom-built JE Labs full-function pre, and First Watt F3 (a 15W single-ended transistor amp). I will soon have a JE Labs 45 SET amp as well. I'm wondering how well the 45 will drive them. (Well, the guy building my amp uses Fortes so I know it does a decent job at least.)
Are there a lot of people happy with 45/2A3 SE amps with Fortes? I know there are a lot of you using these speakers with various push-pull transistor amps with moderate-high feedback.. I'm sure it can sound good but you don't know what you're missing.
