I have a MF ams35i in my main system and swear by it, so much so that I bought an MF A5 and was very happy with it. Then a friend brought an Amp Tastic mini 1 over to try out. Cut a long story short........I sold the A5 and bought the amptastic for £130 delivered and got £800 for the MF. This little amp is astounding, obviously the MF had more power but the Amptastic had more than enough for normal listening levels......and then some. I must admit that I sold the amptastic because I got hold of a CA 840A mk2 and it just bettered the amptastic, at 25 times the weight. If you can get a chance to listen to an Amptastic, go for it, it really will shock you. It did me!
