Why Modern Hi-Fi Is Leaving This Classic Component Behind

The power amplifier is an endangered hi-fi component. Here’s why.

Today, vinyl is at its most popular since the late 1980s. Record sales have been on the rise for the last 18 years (every year since 2006) and new record plants are opening up for the first time in decades. Yes, we’re in the midst of vinyl resurgence.

But one hi-fi component is getting left behind.

Listening to vinyl isn’t exactly the same as it was back in the day. Of the four audio components that were necessary to listen to vinyl in the heyday of generations previous โ€” the turntable, the speakers, the phono preamp and the power amplifier โ€” the traditional power amplifier has fallen out of favor and is actually difficult to find in its historical form.

Integrated turntables, or turntables with a built-in phono preamp, are more popular than ever. And so too are powered speakers, which are speakers with built-in amplifiers. You can pair the two components together, like the Fluance RT80 turntable ($200) and the Audioengine A2+ speakers ($269+), and get a very good entry-level turntable system for less than $500. No external phono preamp or power amplifier required.

Despite mutual moves towards obsolescence, phono preamps aren’t endangered to the same degree thanks to their fairly low price โ€” a high-quality phono preamp can be found for less than $100. Moreover, many integrated turntables still support external phono preamps, which audiophiles still recommend for improving a system down the road.

Traditional power amplifiers, meanwhile, have been almost completely replaced. Integrated amplifiers, which pair a power amplifier and phono preamp, are probably on a permanent rise. The first really popular integrated amplifier was the NAD 3020, launched in 1978, and today, it’s regarded as one of the best integrated amplifiers ever.

But it’s more than just that. Modern-day integrated amplifiers also provide several connectivity options, both wired and wireless, allowing them to become the central hub of the modern hi-fi system. They allow your system to stream music, or they can be hooked up directly to a turntable so you can listen to vinyl. It’s an audio component that can handle both digital and analog, which is why many people (including ourselves) believe it’s the future of hi-fi.

The dedicated power amplifier isn’t completely extinct. However, the ones that still exist are falling out of the mainstream. Very few new power amplifiers come for less than $300 โ€” a sum that could buy you an entire power amp-free hi-fi system, spent differently.

Any audiophile will tell you that the best-sounding hi-fi systems will have each component separate because that ensures that no component can interfere or add distortion to another. For this reason, hi-fi juggernauts like McIntosh, Marantz and NAD Electronics still make dedicated power amplifiers you can buy.

The problem is that they cost a lot because they’re meant for a high-end hi-fi system, usually to drive big and expensive speakers. If you’re looking for a more affordable option, Schiit Audio, a California hi-fi company, makes excellent standalone power amplifiers, like the Vidar 2 and Aegir 2, for under $1,000.

So, unless you’re a true audiophile with pockets to burn, there’s no reason to purchase a dedicated power amplifier. Manufacturers know this, which is why they’ve switched to integrated amplifiers instead.
