1. Cambridge Audio Topaz AM10 Integrated Amplifier

Cambridge Audio Topaz AM10 Integrated Amplifier

The reason we start with the Topaz AM10 amplifier is simply because it falls right in the golden middle, thus sticking to the classical concept of what a good high end entry level amplifier should be like. AM10 by Cambridge Audio is a slick all-metal box with a stylish brushed aluminum front panel housing a ruffle-free functionality that can suit all practical needs of an audiophile. Don’t be fooled by the amp’s price against its more expensive relatives as it will not make you disappointed by what it can give. The seemingly insufficient 35 watts per channel can do the job well if placed in the right context – with the suitable speakers it can give a spacious soundstage with a strong midrange image for your living room or even fill a small cozy basement lounge with a hi-fi sound. Topaz AM10 is turntable friendly – with built-in phono stage you can instantly connect your turntable and spin some old vinyl of yours for your friends and guests in case playing CD’s is just not atmospheric enough. Designers of the amp stayed focused on providing the overall pleasant sonic experience, so this Topaz AM10 even has toroidal transformers normally found on separate high end devices. This helps to get a better bass response and a deeper, richer sound all together.

That said it must be noted, however, that the adequate match-up of AM10 with the speakers is crucial for getting the most audio quality. But when this part is done you can enjoy a fully submerging audio experience with a variety of sound sources: for your everyday use AM10 is conveniently ready for iPod, MP3 player or a smartphone right from the front panel. Rear panel carries inputs for the more basic hook-ups like CD player, tuner, DVD player, TV or Blu-ray transport.

Pros
  • Affordable price
  • Solid all-metal build and modest stylish look
  • All standard inputs for laid-back audio experience
  • Turntable ready
Cons
  • Power output imposes certain limitations

2. YAQIN MC-13S EL34 (6CA7) 4 Vacuum Tube Integrated Push-Pull Amplifier

YAQIN MC-13S EL34 (6CA7) 4 Vacuum Tube Integrated Push-Pull Amplifier

YAQIN MC-13S can be considered one of the best class A integrated amplifiers, namely the best integrated amplifier under 1000 dollars. Let’s see why. The very foundation for the reasoning can be found right in the amp’s full name: MC-13S is a tube amp with the circuitry based on the push-pull design that has been proven over time to deliver quality audiophile sound. But those are the expected basics: necessary but not sufficient. So to support the promising design YAQIN equips the MC-13S with high quality components made by a number of world’s reputable electronics manufacturers. Such consistency in quality approach makes it possible to provide a reliable path for the sound signal to pass. Obviously, being the tube amp MC-13S is a rather bulky device, so you can imagine how much pain it can become reaching for the back panel to make connections. Not with this amp! Since MC-13S has 4 line inputs switchable from the front panel, you’ll only need to make you cable connections once and then work your way between the auxiliary channels as necessary.

You may wonder what exactly MC-13S may be missing so that it can fall under a thousand dollar mark. Well, the price paid for the sound quality is the lack of extra features normally found in more expensive amps. With the target price category in mind, the circuitry was designed with the primary focus on the sound quality that a tube amp is expected to provide. So in the end you get pure minimal functional quality, which seems more than fair.

Pros
  • Good sound quality with the tube warmth feel
  • State-of-the-art design and look with a durable build
  • 4 switchable line inputs
  • More affordable compared to other multi-featured tube amplifiers
  • Convenient analog VU-meter
Cons
  • Bigger and heavier than a solid-state amp
  • Requires maintenance on occasional tube replacement
  • Limited on features

3. Onkyo A-9050 Integrated Stereo Amplifier

Onkyo A-9050 Integrated Stereo Amplifier

Now that we’ve looked at two amps representing somewhat conventional approach, let’s turn our heads to a digit in our quest for the best integrated amp with DAC. Onkyo A-9050 comes with Wolfson DAC able to decode at 24 bit/192 kHz resolution. Although among digital enthusiasts this is only considered semi-professional level, this is still much better for providing quality digital sound. This can be even more pleasing if you keep in mind that having a DAC on board is not to be taken for granted for most amps under $500. Another point of pride of this Onkyo A-9050 is the Three-Stage Inverted Darlington Circuitry that combined with DIDRC filter works toward eliminating virtually any distortion. This is especially important for a digital-capable amp operating at 75 watts of output power.

A little drawback for the true old school audiophiles is that the sound produced by A-9050 comes off a bit on the bright side while missing that warmth and richness praised by audio purists. This, however, may not be the issue for those looking for a full-bodied bass that Onkyo A-9050 can deliver, which is awesome for the price.

Another good reason to consider Onkyo A-9050 the best integrated amplifier in its price range is its set of inputs (1 optical, 2 coaxial, 5 analog, and 1 phono) that gives plenty of options. Connect your turntable or play music directly from your computer in addition to the basic input features. To make it just a notch more appealing Onkyo A-9050 comes with a wireless remote control.

Pros
  • Digital 96kHz/ 24-Bit inputs
  • Great value for the price
  • Remote control
  • A good set of input options
Cons
  • Not the warmest sound
  • The controls can be hard to read
