forte 4 VS. forte 4a VS. forte 7


I have forte model 4, and very satisfied with it.
But I wanna know the differnce between 4 and 4a.
Does anybody know the difference?
And how about forte 7?
Thanks for your opinions!

I am not sure I have the right model numbers in my head but could it be a remote control?
THE FORTE 4 IS 50WATTS CLASS A AND THE FORTE 7 ARE 75 WATT CLASS A MONOBLOCKS. THEY LOOK IDENTICAL TO THE 4 ONLY MORE POWER.I HAVE A FORTE 4 FOR A SECOND SYSTEM AND MY FRIEND HAS THE 7'S DRIVING VANDY 3A SIGS. WITH EXCELLENT RESULTS.
