The MF A300 and for that matter the MF 308 amps are definitely worth tracking down. Exceptionally clean sounding amps. Plenty of power. Superb construction. I would also recommend the MF CD PRE 24 preamp/ cd player as your front end and source. I have used a CD PRE 24 for 9 years now, first with an A300 and then with a Prima Luna Prologue 5. Nothing I have owned since has surpassed the MF products from the early 2000s.
