So how does one summarize all this? I think the Moon 390 and 330A represent the best fully featured amplification system I have heard at under £10,000, and calls into question why one would ever need to spend more. I have totally fallen in love with the sound, the functionality, the look and the quality of these Canadian beasts. Playing music has never been more pleasurable than it has been these past few weeks – I would happily spend the rest of my life with these Moon pieces at the heart of my system. Make no mistake, they are irresistible. Only audition if you are ready to handover the money to your friendly Moon retailer!
