Hi im new to valves Now looking at an icon audio stereo 40 or 50 or puresound A30 I live in the sticks and dont drive after an accident so am stuck for going to auditions. What sort of advice could you ppl give regarding speaker selection for such amps ? 500 uk range or lower ? I have a cambridge audio cd player and rega deck. Room is about 12-14 ft square I listen to jazz blues modern but not heavy stuff. Any advice would be greatly appreciated Chris D
