Mastersound Evolution 845 Integrated Amplifier

"When appropriately partnered, the Mastersound Evolution 845 is a delight to listen to, especially with classical and vocals. It breathes with live, unamplified instruments and feels like it gives the instruments the chance to sing out as they were made to.

 

Like many good amps, this starts from the midrange out. The mids are intensely satisfying, in the way scrambled eggs on hot buttered toast on a cold winter’s morning is intensely satisfying – naughty, but nice. Midrange sounds here are lithe and entice you to listen longer. No, they won’t turn PJ Harvey into Ella Fitzgerald, but the Mastersound’s midrange combines vocal clarity and articulation with a huge soundstage and a seductive richness that draws you in."

 

"That’s the magic of the Mastersound Evolution 845. Turn it on, wait half an hour and the sound is so seductive it’s hard to resist its charms, even if what you normally listen to (both in terms of audio technology and the sort of music at which it excels) is very different. If you think valve amps are all about squidgy soft and warm sounding, the Mastersound is the natural way to show just how wrong preconceptions can be."

The Evolution 845 is massive in size for a 55w integrated amplifier, and it certainly delivers in the power department, able to drive many speakers of various sizes and loads.  It will be delicate or powerful when required, 845 tubes on a Class A parallel single-ended dual mono design, a beautiful balance of grace and might. 

 

Our favorite tube integrated amplifier so far, and the premier German magazine Image HiFi thinks highly of it too, awarding it the Best Tube Integrated Amplifier of the Year, with award ceremonies at the Munich High-End Show 2013.

 

It's also a sight to behold, a conversation piece for sure, beautiful in its big size.  We wouldn't have it any other way.
