Any tendency toward tightness was mitigated by the Puritan PSM156 mains purifier ($2400), a six-outlet unit into which I’d plugged all my electronics except the Krell. I also used two Puron plug-in AC line conditioners ($295 each), cylindrical devices about the size of a KT88 tube. Inserting the Purons into the wall receptacle and/or the first outlet of a power conditioner will reduce system noise, the manufacturer claims. The Puritan, meanwhile, is said to battle both common-mode and differential-mode interference, remove DC offset, and scrub the earth-ground line of sonic impurities. It also offers 9000A of surge protection.

Adding first the Puritan and then the Purons made the air in classical recordings seem a bit more expansive, and music went up a step in effortlessness. The Puritan and Purons also subtly increased my system’s resolution. When, during this review, I spent a few days auditioning a 30-year-old Aragon 4004 MKII power amplifier—I was trying to decide whether I should keep it—the Puritan ably suppressed some low-level transformer hum. The three Ps—Piegas, Puritan, and Purons—played well together, but even without help from power-massaging devices, the Swiss speakers impressed with imperturbable precision and the ability to express fine detail.

Their new two-channel power amplifiers that enable the speakers’ ability to be driven by RCA or XLR cables instead of speaker cables allow you to send your music by Bluetooth directly to the speakers in another place in your home, such as your dining room. Arylic’s Bluetooth S50 Pro+ Receivers eliminate cables from your hi-fi system altogether. A very nice setup indeed!

It’s this strength in depth that makes the KEF so convincing. I still feel that a few little tweaks to the software would reap benefits, but I can’t argue with the way it combines an extensive and practical specification that makes it an ideal one-stop shop with a level of overall performance that is truly outstanding. When you listen to the LS50 Wireless II it’s easy to forget about the convenience angle and concentrate instead on the sensational level of sonic performance. It isn’t cheap, but it’s unquestionably a superb all-in-one system that should be on anyone’s shortlist at or near the price.

The new Trapeze have a claimed sensitivity of 88dB/W/m and a nominal impedance of 8 ohms (with a minimum of 6.5 ohms at 20kHz). That kind of electrical load shouldn’t be an issue for any good quality price comparable amplifier.

These floorstanders prove relatively unfussy about positioning. Audiovector recommends around 70cm out from the back wall as a good starting point, but in use the speakers seem easy-going enough to be placed a little closer if you have to. It all depends on the size and construction of your listening space, of course. In our 3 x 7 x 5m (hwd) test room, the recommended distance works well, giving a good balance between bass weight, tonality and stereo imaging.
