Performance

Over the decades that Unison Research have been designing and building audio products, they have always listened to the concerns and comments of their valued customers; and over time they have realised that those customers' needs have changed. As a result of this ongoing willingness to listen, they are constantly developing new and existing products to suit the ever-changing needs of their customers. Enter the latest version of the long-standing Performance integrated amplifier.

The Performance is a single-ended Class A integrated amplifier with a parallel internal layout for ultimate sound-staging and an authentic valve experience. This latest version offers increased power, when compared to its predecessor, while staying true to the important characteristics of timeless aesthetics and pure musical pleasure.

The few visual changes are due to functional necessity, such as the insertion of large thermic radiators on either side, and the two stainless steel screens that act as a cover. This cover is amegnetic, with low heat conduction and it's used to prevent the heat generated by the six KT-88s from reaching the circuitry below, which benefits the sound quality as well as overall reliability.

As with all high quality integrated amplifiers, the Performance is laid out in dual-mono configuration. Within the single chassis there are effectively two identical but fully independent amplifiers. This design avoids any possibility of interference, whether internal or atmospheric, between the two channels.

Unison Research's extensive knowledge of transformer production has resulted in a specially designed set of transformers for the Performance, which help the amplifier to give a true best-in-class performance. The parallel single-ended ultralinear configuration would be completely undermined if there were not suitably developed transformers in place, as the special design effectively allows the KT88 tetrode valves to be used as triodes. 

Valves are used for all the amplification stages, and all valves operate in pure Class-A mode. The pre-amplification and power stage drivers are based entirely upon triodes, with the use of high-grade ECC83 and ECC82 tubes. With these valves it is possible to obtain excellent linearity and a virtual absence of odd-order harmonic distorsion. Both these stages are designed with triodes in parallel and use automatic biasing for a long and reliable life. This allows the output impedance of the two circuits to be usefully reduced, while total harmonic distorsion is also reduced and signal to noise ratio is increased.

As well as a clear array of inputs and outputs on the back-panel - including separate speaker terminals for 4Ω and 8Ω loads - the Performance also benefits from a power output for the Simply Phono. So the amplifier also acts as an upgrade power supply for Unison Research's introductory phono stage.

The Performance is a true high-end masterpiece that benefits from both a long-standing reputation and up-to-date technology.

Recommended by my dental hygienist
These probiotics help maintain a healthy balance of bacteria in your mouth, which already improved my gum health and reduced bad breath. This product was recommended by my dental hygienist.

Eliminated continual bad breath and some thrush
I’ll keep this short - I’ve had oral thrush since taking antibiotics years ago. My breath was always good though so I never cared much (though I do eat probiotic-rich foods whenever I can). Lately, I started developing a gross taste in my mouth that and my wife was saying my breathe wasn’t great - not a fun thing to hear. I tried mouthwashes, general probiotics, oil of oregano, etc...nothing worked. I bought these on a whim and began taking them just 5 days or so, my breathe is no longer bad. The thrush has minimized as well, though is still present toward my the back of my tongue. Amazing. I don’t write reviews and wasn’t paid to do so for this product - just bought randomly, hoping it’d help, and it did. I’m sure it won’t work for everyone since everyone’s body is different, as are the reasons you might be experiencing bad breath, but for me, this is amazing. BY THE WAY: I see reviews saying they took these like pills. That’s not going to work, you have to let them completely dissolve I. Your mouth as the instructions say!

A Lifesaver for Dry Mouth, Without That Weird Aftertaste 👏
Size: 4.3 Ounce (Pack of 1)
If you know, you know: dry mouth is not just an inconvenience, it’s downright uncomfortable. I’ve tried several brands over the years, but Biotène is the one that consistently keeps my mouth feeling fresh without that overpowering artificial mint or gritty texture. This formula is gentle but effective, no burning, no foamy overload, and no funky aftertaste. It’s also a huge win that it’s sulfate-free and doesn’t irritate my gums like some drugstore pastes do. The mint is subtle but refreshing, and my mouth actually feels hydrated afterward (which is wild to say about a toothpaste, but here we are). If you deal with dry mouth from medication, menopause, or just bad luck, this one’s worth every penny. ✨ Pro tip: Keep a travel size in your bag if you’re heading out for the day. Nothing ruins a coffee date like feeling like your tongue is made of sandpaper. 10/10 recommend.

Dry Mouth
Size: 4.3 Ounce (Pack of 1)
I have been diagnosed with Dry Mouth, what a problem this is! My dentist recommended toothpaste for dry mouth; I selected Biotene Fluoride toothpaste for daily use. I definitely use it at night before going to bed to help keep my mouth less dry. I also use Biotene mouth wash and other products that I'll rate another time. I love this toothpaste; I believe it's helpful for my diagnosis.

Biotène Fluoride Toothpaste for Dry Mouth Symptoms
Size: 4.3 Ounce (Pack of 1)
I have been using this toothpaste on and off for a few years ever since I got a dry mouth. It is very good and leaves your mouth feeling fresh. Unfortunately it doesn't get rid of your dry mouth.
