Denon PMA-A110

Yes, I am a fan of Denon, but this model, like the PMA-600NE, absolutely deservedly made it to my list. PMA-A110 is specifically designed for audiophiles who demand high-quality sound from their audio equipment. Of course, this integrated amplifier priced under $5,000 will not be affordable for everyone, but believe me, it is worth every penny. So let’s take a closer look at it.

First of all, I would like to point out that this model has wireless Bluetooth and Wi-Fi connectivity (it supports Spotify, Tidal, etc.). However, I dare you to be disappointed by the lack of tone controls or room correction features.

In terms of appearance, the Denon PMA-A110 doesn’t just look elegant – it looks even luxurious! Yes, it really has a premium build quality, with an aluminum front panel and chassis made of aluminum and copper for a perfect balance of rigidity and vibration damping.

You get 80W of output power per channel (8 Ohms, 20Hz – 20kHz, THD 0.07%), which makes it capable of creating an atmosphere even in quite spacious spaces (the compatibility range is from 4 to 16 Ohms).

The PMA-A110 is based on high-quality components such as the advanced AL32 Processing and a high-speed, ultra-low distortion preamplifier.

Integrated amplifiers buying guide

Inputs and outputs

When choosing and then purchasing an integrated stereo amplifier, the first thing you should pay attention to is the connectors it has. Then, proceeding from your needs, you should understand what each connector is for and what equipment you can connect to it to get quality sound.

All standard amplifier models have multiple RCA inputs. These are line inputs designed to connect your main sources (CD player, DAC, etc.). If your unit has no separate phono input, you may also use them to connect a turntable with an external preamp.

As I already mentioned, the phono input is for connecting a turntable that doesn’t have a built-in preamp, so you don’t have to use an external one. The inputs can be configured as MM (regular) or MC (for true audiophiles).

XLR connectors are designed for balanced audio signals. They are used in professional environments with a lot of equipment because they suppress maximum external noise and work great with long cables (in studios, equipment is often spaced far apart). However, in the home, using XLRs can play a cruel trick on you by making the sound flat.

Digital optical and coaxial inputs are used for older generations of equipment. So please pay attention to their availability to collect, store, and use the equipment for years.

From the additional, not the most important (but maybe for you it is the most) may be USB connectors (for using external media, like flash drives, or even PC), HDMI (for broadcasting digital sound from TV), additional subwoofer outputs (if you like deep volume bass) and headphone output (well, here everything is also clear, it is for introverts and greedy people who like listening to music alone), which is most often located on the front panel.

Built-in Bluetooth, Wi-Fi and streaming services

What do Bluetooth and Wi-Fi wireless connectivity give you? Convenience, ease, and speed of playback from your devices (smartphone) and use of streaming services or home ecosystems (like HEOS).

You may be surprised, but the more expensive an integrated amplifier is, the fewer chips it has. It is because since signal quality is the last thing to think about (they often work out of tune), manufacturers don’t add this feature to high-end equipment (>$2000). Instead, users must connect additional equipment to their amplifier as needed. And while signal quality has increased recently, you probably noticed that not all models in my article have advanced network features, so be sure to pay attention to that.

Amplifier classes

Another characteristic of an amplifier is its class. You may see labels such as A, A/B, G, and H, D. Specifying the class of the amplifier tells you what efficiency the unit operates at and how much cleaner sound you can get as a result. They differ in design (single-ended and Push/pull (forced draught)) and the principle of operation (conducting the signal throughout its 360-degree cycle). In fact, each class is an upgrade of the other, eliminating the disadvantages of the previous class and… acquiring new disadvantages. Our detailed article lets you learn more about the differences, advantages, and features of the different classes of amplifiers.

Given that many components influence the quality of the final sound you hear in your system, the amplifier class is not the main characteristic. Therefore, it is not that important in your final choice of unit.

Solid state and tube amplifiers

The struggle tube amp vs. solid-state will apparently be eternal, as the camp of fans is divided into two more or less equal halves. So, you will have to study this issue in detail.

The main difference between the two is how they amplify the signal. It’s easy to guess that tube amplifiers use tubes, and solid-state amplifiers use electronics (transistors). Sounds like a war between analog and digital sound, doesn’t it?

So with a tube amp, you get a warmer, more enveloping sound with great bass and midrange, and some overdrive error (which is exactly what characterizes the sound as natural). On the other hand, solid amplifiers produce a powerful clean sound derived from the electrical signal, which depends directly on the quality of the components used.

By reading more about the differences between these two types of amplification, you will be able to understand that your choice will be determined by the genre of music you prefer and how loud you want it to be played. So, take the time to research this question, and pick something complete to your taste.
