Shopping for a amplifier that will deliver the best sound quality is tricky because there are so many available. To the untrained (or lightly trained) eye they are complex and perhaps even mysterious pieces of equipment. Without a degree from MIT, it’s difficult to determine which is the best value for a set amount of money. In fact, it can even be difficult to understand precisely what you need.

Yes, it’s possible to compare specs and up with the best amplifier to play your vinyl records with optimal sound quality. But even that approach comes up a big short. An amplifier fora turntable has a spec list as long as your right arm (as a detective in a crime drama would say of a suspect’s rap sheet). Which specs are important? Which are “nice-to-haves?” Which are marginal or irrelevant? And within each spec, how exactly do the numbers and percentages translate into real world performance?
So ways must be found to make sense of it all. The smart thing is to zero in on the key properties of the device and compare them in a way that bypasses numbers and percentages as much as possible. One thing to keep in mind is the difference between amplifiers and integrated amplifiers. An integrated amplifier contains both the power amplifier, the prem-amp and some controls. An amplifier is just the power amplifier. That’s the technical distinction. However, the two terms are so close that they are unlikely to be used with much precision.
Where those numbers and percentages are needed in order to find the best Hi-Fi amplifier — for instance in power and frequently response–do a quick dive to get a rudimentary understanding of what each means. (Here is a look at power and here is frequency response.)
Many of the decision points on a amplifier purchase decision are not inscrutable high-tech measurements that only an audiophile can understand. They are pretty relatable items such as whether the amplifier is compatible with the rest of the home audio system, whether it physically fits into the space where it will “live,” if it has proper phono input and, yes, whether it will look cool as it plays your vinyl records.
Scat Records has a nice rundown of what to look for in an stereo amplifier for a turntable. They point to five elements as must-haves: built-in preamp/phono input; Bluetooth connectivity; tone control; power and speaker pair-ability.
The others go almost without mention (but we will). The value of Bluetooth connectivity is obvious. Tone control and power also are table stakes. Speaker-pairability – somebody must come up with a better descriptor – is important to mention here. It’s a bit ironic, since the ability of an amp to complement a wide range of speakers is not specifically related to the relative ability of amplifier to play vinyl.
But it’s a big deal. Whether an amp plays nicely with a wide range of speakers is likely to fall through the cracks while shopping. It shouldn’t.
Why the Big Price Gap?
One of the interesting things about the world of amplifiers is that the range of prices seems bigger than in other categories. Of course, all elements of a stereo system – indeed, anything that has a price tag on it – have a range of costs. Good sound quality has a price, of course. But the disparity in the amplifier category takes this to the extreme. It almost seems that completely distinct product categories are being compared. Prices go from far less than $100 to far more than $1,000. That is quite a window.
Prices also are determined by exactly what is included. Home theater amplifiers are different than home audio. This leads to a tedious discussion of how vendors and retailers label their products. There are differences between a power amplifier, an AV receiver and an integrated amplifier (not to mention pre-amps, which are sort of the remora fish of stereo equipment). A savvy shopper is should be familiar with the basic differences.
This site will go deeper into those definitions in the future. The main point is that how much functionality is squeezed into one unit clearly influences price.
And, finally, expensive equipment is just better put together. This is a very important topic in electronics. Advances in fabrication processes is enabling transistors and other elements as well as the conductive materials that connect them to be be put closer and closer together. That is why devices grow ever smaller. (Check out the “portable” phone in the movie “Wall Street,” which was released in 1987. Non-conductive materials don’t stop all signals however. Thus, poorly shielded and protected equipment is prone to interference. There are good question to ask on this topic if you see a deal that looks a bit too good.
In a sense, no part of a stereo setup is more important than any other simply because each one has the potential to limit or ruin performance. That said, the turntable amplifier is vital. Your choice can result in a system with great sound quality with expansion options or one that is limited both in quality and flexibility. In some things, a little knowledge is a dangerous thing. In amplifiers, a little knowledge is just what the doctor ordered.
There are a lot of Amplifiers to Choose from. The Best Advice is to Educate Yourself
There is no one most important or weakest important element of a traditional stereo system. That simply because each is a link in a chain that hopefully leads to good sound quality. A failure or under performance at one point is just as debilitating as a failure or under-performance at another. Vinyl albums full of gunk (that’s a technical term for, well, gunk) means that the vibrations and resulting current being created by the diamond needle traveling through the grooves will be inaccurate. Bad performance by the preamp on those tiny currents also kills performance. And on and on, up the line.
That said, the choice of amplifier requires special attention. For one thing, the similarity in describing the various attributes in the overall category — power amp, phono stage/preamp, integrated amp — relate to real and significant differences in functions. But they tend to blend together. This haziness may be on the part of consumer, the vendors trying to make their products seem as broad as possible or both.
On top of this — as mentioned above — is that there is quite a gulf in the pricing. It is important to keep some things in mind: It’s easy to pay for functionality that you don’t use, it’s easy to overlook elements that really will come in handy (such as Bluetooth capabilities) and that how well the products are constructed really is very important.
At the end of the day, integrated amps (devices containing both preamps and power amps) simply do more things than other elements of the system. Turntables turn the records and make sure the cartridge is positioned correctly. Speakers reproduce the signals sent to them. Amplifiers, however, are responsible for boosting the signals, controlling tone, connecting to peripheral devices such as tuners and really are the main interface between the system and the human.
Turntable Amplifiers to Consider from Yamaha, Denon, Cambridge, Fosi and KEiiD
Note: All images are courtesy of the turntable amplifier manufacturer. Hover over images for a closer view (in most cases). Vendors have unique short hands for specifications. I’ve more or less left these unchanged, so the capsules are a bit inconsistent. The paraphrased comments are subjective (and, indeed, sometimes contradictory). Folks sometimes use equipment incorrectly and then complain. Problems mentioned may have been addressed by the manufacturer. Comments about products that come broken generally are not included. Amazon has a tremendous amount of information and feedback on the what it sells and is a recommended element of your shopping research.

The unit connects as many as 4 speakers. A/B switching enables all to be played at once or separate zone operation. The unit weighs 15.74 lbs. and has dimensions of 20.87″ (W) x 15.75″ (D) x 5.51″ (H).
