STEELHEAD er ren, stille og skudsikker med enorm fleksibilitet og er både en tweak-o-holic tube-elskers drøm og en hifi-anmelders reference.

“Overall, the Steelhead delivered the best vinyl playback I’ve heard from my system. It combined speed, frequency extension, resolution, harmonic structure, focus, air, stage depth, image specificity, and, most important, overall musical coherence in a way that made the music seem to fly from the speakers unrestrained by mechanical or electrical bounds.”

– Michael Fremer, Stereophile, December 2001 –

“…the Steelhead is a very fine phonostage. And no, you’re not just paying for flexibility — the damn thing sounds great and very easily competes with a purist-design…and well, the Steelhead is so pretty. I guess you could say I’m a fan of the aesthetic. Very MANLEY.”

– Scot Hull, Part-Time Audiophile, January 2011 –

 

“The Manley Steelhead is a tube phono pre-amp with all the qualities we love about tubes and none of the limitations of those thermionic devices…I lay odds that whatever kind of audiophile you consider yourself to be, you’ll find yourself more involved in the music.”

– Marshall Nack, Stereo Times, December 2002 –

“I’ve had my Steelhead RC for 7 years now. Being an audiophile, a lot of changes have been made to my system through the years, but I’m positive that the Steelhead will never leave.”
