I have been driving my O2mk1 with a border patrol SE300B through my SRD7 mk2. The amp is an 8 or 9 watt which couples to a huge external power supply. I also have the balanced B22 and previously the 717 and the T1s. I totally agree that the amp makes a big difference. The only problem now is that I am getting a bit of hum and I am trying to sort it out. Any opinions will be greatly appreciated. I have tried unearthing the power cords but the hum is still there - mixture of hum and tube buzz.
