PL500 II - Audio Show 2016 Review

Roy Gregory from The Audio Beat was introduced to Monitor Audio's PL500 II loudspeakers at the 2016 Audio Show and named it one of the Hot Products of the show...

"It looks even bigger in the flesh, while standards of fit and finish put many a high-end wannabe to shame (irrespective of price) with a black lacquered central cabinet visually offset by the leather baffles and high-gloss veneers on the larger enclosures top and bottom."

" attractive and impressive package."

"...there’s far more to this speaker than just a pretty face, with plenty of technology to back up the bold visual statement, a fact underlined by the sheer scale and power of the sound on offer."

"...this wasn’t just about brute force, the speakers proving capable of considerable air and delicacy when required, making these genuine high-end contenders."

"...this is a product that threatens to cut a lot of the competition off at the knees."

PL500 II CES Launch!

"The surprise of CES for yours truly, the Monitor Audio Platinum PL500 II."
                                                                           - Jonathan Valin, The Absolute Sound

"...exceeded sonic expectations, delivering high-end quality (think Raidho-like) beyond those well-known brands' respective price categories."
                                                                           - Julie Mullins, The Absolute Sound

" a world where seven-driver, three way designs featuring custom-made drive units in a cabinet that stands as tall as a man can cost the spendy side of $100,000, a loudspeaker that sounds this good commands respect."
                                                                           - Alan Sircom, Hi-Fi +

Our PL500 IIs stand tall in this Bristol Show 2016 roundup

Revered custom install magazine Inside CI provided a review of the most impressive products at The Bristol Show 2016. Featured first was our very own flagship floorstander, the PL500 II:

“Arguably the most exciting stereo presentation I heard at the show came from Monitor Audio, which was playing a variety of CD FLAC rips through its flagship Platinum II floorstanders. Fronted by Chord Electronics DAC/digital preamp/headphone amp DAVE (pictured above), imaging and dynamics were grin-inducing. They may retail for £15,000 a pair but frankly, in the world of stratospheric premium Hi-Fi, I think this big MAs may well be a bargain. “
