Hiya John, just wanted to say thanks very much for upgrading and updating my gear, have done just as you advised left them both powered up and have to say they are singing just lovely. Changed the mc eroica and what a difference. My other half is so impressed with her cd collection saying she’s hearing sounds she never heard before, just loving listening to Kenny G and Santana . Me,well Dark side of the moon is just amazing. Some of my mates who all use MF gear are impressed to the point that sometime in the future will be intouch. I think as the amps get a few months running in can only get better. Thanks once again and I would recommend you to all that may read this,well worth the money. Next time I’m down your way hope to call in and meet up.Thanx again. Mick C.
