Musical Fidelity A1 Class A Integrated Amplifier
Musical Fidelity A1 Class A Integrated Amplifier
Pure Class A magic from Musical Fidelity! The original design of this amplifier was by Tim de Paravicini who is as legendary an audio designer as they come and the new and improved A1 features the same circuit with improvements to better dissipate the heat and improve the performance and lifespan of the product.
Although you will need to be somewhat careful when matching this amp to a given speaker, don’t judge it by the rated 25 watts per channel. As we have found with the Sugden product that we carry, Class A watts pack a lot more punch! This amp will drive any mid efficiency speaker with ease, if you aren’t sure please get in touch and we’ll help guide your purchase.
This amp sounds absolutely fantastic, punchy with a capital P but with a nice warm, smooth sound that you will never tire of. You get lots of line level inputs as well as a switchable Moving Magnet/Moving Coil phono preamp that adds to the tremendous value of this amp. You also get a nice basic remote control in the box as well which allows you to adjust volume and mute from the comfort of your chair.
If you are looking for a taste of the high end but want to spend “reasonable world dollars” this is about as good as it gets…
