HI-FI+ | Mu-so Qb 2nd Generation | Wireless Loudspeaker of the Year , Dec 2019
"The Mu-so and especially the Mu-so Qb 2nd Generation both show how hard that task must have been and how brilliantly Naim nailed it!”
What Hi-Fi? | Mu-so Qb 2nd Generation | 5 Star Review, Oct 2019
"the greatest value is not found in its features or design, but in a sonic performance that will effortlessly dispense of any one-box rival within a few hundred pounds of its asking price."
Trusted Reviews | Mu-so Qb 2nd Generation | Highly Recommended , Oct 2019
"The overall tonal balance is cleverly judged, and the amount of detail the Qb 2 dredges out from even dense and murky mixes makes it sound open and, as a consequence, entirely accomplished."
Good Housekeeping | Mu-so Qb 2nd Generation | Review , Oct 2019
"The Naim Mu-so Qb 2nd Generation has a rich bass and near faultless treble. And at 300W it'll definitely blow your socks off."
