“History doesn’t repeat itself, but it often rhymes.” So goes Twain’s aphorism.
And as the vinyl resurgence ploughs on, something of that sentiment can be felt in the kinds of products that are undergoing discounts as part of this year’s Prime Day sales.
Most vinyl enthusiasts will know the score: a beloved old turntable and an up-to-date, perfectly functional hi-fi system. Both are great things to have, but sometimes the sonic limitations of retro gear can stand out on more modern systems.
Alternately, you might have bought a budget turntable and have a pair of active desktop speakers, and now you need that crucial phono stage element to get them working together.
For those in either situation, this Cambridge Audio Alva Duo phono preamplifier is a discreet and inexpensive addition that will give your vinyl system the sonic upgrade it deserves. Why repeat, after all, when you can rhyme?
Right now, the Alva Duo is seeing a £50 discount, and is available for £249 from Amazon.
This five-star outboard phono stage is compatible with moving-magnet (MM) and moving-coil (MC) cartridges. In an unusual, but highly convenient twist, the Alva duo also features a built-in headphone amplifier stage and volume dial.
This is great news if your old-school turntable doesn’t have a headphone socket, and means you can blast your records late into the night, without making enemies of the neighbours.
Note: if this is your plan, you’ll also want a solid pair of wired headphones, for which you can consult our top wired headphones of the year.
For any newbies to the world of turntables, adding this Duo phono stage to a pair of active speakers will make sure your records are conveyed with a smooth, full-bodied sound.
Admittedly, our current favourite phono stage, the Rega Fono MM Mk5, will provide a punchier and more rhythmically precise sound for a similar price, but it lacks some of the extra features that make the Duo so irresistible.
Most of the budget to mid-price turntables that we would recommend using the Duo alongside will be likely to use an moving-magnet cartridge as standard, but if you wanted to explore moving-coil options at any point, the Duo allows you to expand your horizons. A word of warning, though: MC cartridges tend to be a lot pricier.
Whether your hooking up a desktop vinyl system or refreshing a golden oldie, we think this deal is worth serious consideration. With a stylish look, dynamic sound and great features, the Alva Duo could be yours for a deal price of £249 from Amazon, Richer Sounds and Cambridge Audio.
