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.

Beautiful Sage Green Set That is Super Soft and Cozy!
Color: Sage Green, Size: Queen
​I am absolutely in love with this sage green bedding set. The queen comforter has a gorgeous pre washed crinkled texture that gives the whole bedroom a really cozy, aesthetic look without needing to be ironed. It is incredibly fluffy and has just the right amount of weight to it, making it perfect to use all year round. The brushed sheets that come with the bed in a bag are surprisingly soft against the skin, and everything fit my queen mattress perfectly right out of the box. ​The color is a beautiful, calming sage green that matches my room decor perfectly. I have already washed the sheets and comforter once, and they held up great in the machine without losing their softness or shrinking.

Soft All-in-One Queen Bedding Set With Lightweight Comforter
Color: Beige, Size: Queen
This 7-piece queen bedding set is a solid all-in-one option for anyone looking to refresh a bedroom with a clean, aesthetic look without spending much. The comforter has a lightweight feel with a soft crinkled texture that gives it a relaxed, lived-in appearance while still looking modern and put together on the bed. The included sheets and pillowcases are soft and smooth against the skin, with enough comfort for year-round use. The comforter itself is light but still provides enough warmth for most seasons, making it practical for both warmer and cooler months. Fit is generally accurate for standard queen mattresses, and the set comes complete with everything needed, which makes setup simple and convenient. The overall look is cohesive, with a soft beige tone that blends easily into most room styles. While it is not a luxury heavyweight bedding set, it offers good comfort, style, and value for the price, making it a strong choice for guest rooms, first apartments, or an easy bedroom upgrade.

Standard Comforter. Thin Scratchy Sheets
Color: Dark Green, Size: Queen
This is an ok set for the price. I’m mostly using the comforter for a guest room. It’s a light-medium thickness. The color and size are true to description. The sheets that come with the set are very thin and not as soft as the comforter.

Comforter is nice, sheets are alright. Color is true!
Color: Burnt Orange, Size: Queen
This is a decent comforter set. The actual comforter isn’t too heavy, and would be perfect spring through fall in the Midwest. It’s a true queen size fit and the burnt orange color looks as it does in the photos. I ordered these before it mentioned they’re polyester. They definitely don’t feel as breathable as cotton sheets but as far polyester goes, they feel soft. The sheets wrinkle easily but the comforter feels durable. If you’re looking for an affordable sheet set and you’re cool with polyester, this is a good option. Also of note is that 2 of the pillow cases have a little extra fabric on the outer rim to look more “decorative.”
