Hi! Someone has offered me a second hand Musical Fidelity A3.5 integrated amplifier and I am considering seriously this offer. Also I have noticed that the A3.5 line is already discontinued and the life of these products has been very short. Can anyone tell me why? Is there any problem with them? Any good/bad experience with the MF A3.5. integrated? Any input will be welcomed. Thank you in advance for your help!
