I’ve owned my music fidelity B1 amp from new it’s matched brilliantly with a Systemdek IIX with a rega 3 arm & a recent upgrade of a goldring E3 cartridge with Celestine DL5 speakers. The amp is starting to play up which amp would you recommend to replace it as at the time of purchase I had a store near me (Westwood & mason) that let me play with a lot of kit to make my decision and how great it was but now where do I start with new kit?
