Now some clarity about the LRS with the Sphinx Magnum. After listening to the full impact of the Magnum with the Falcons, it became clearer to me that the Magnepan LRS needed more oomph to realize a larger presentation. I switched over to my reference amp, The Rogue Audio Pharaoh. Boom, full-scale, and solid tuneful bass. The Pharaoh has a monster power supply that can handle low sensitivity and 4-Ohm load speakers with more brute force, along with finesse. Of course, it is twice the price of the Sphinx Magnum.

The Falcons at 15 Ohms presented a friendlier load to the Sphinx Magnum. Voltage vs. Current. You could hear some of the tube-adjacent sound of the Sphinx Magnum coming through. Ok, it was getting late, so I opted to go for headphone listening so as not to disturb those who were sleeping upstairs. I wear headphones when doing radio shows and for listening to critical mixes of pre and mastered recordings. I was surprised by how nice sounding the headphone experience was on the Magnum. The MOSFET amp section makes for an easy and relaxing listening session. Oh yes, there was detail and the good things your ears beckon for.

The Vibelink also has a Post-Filter Feedback (PFFB) circuit to minimise distortion and enhance clarity across different speaker loads, it is claimed. While affordable TPA3255-based amplifiers and ESS Sabre DACs abound, the WiiM distinguishes itself on several fronts. The unibody aluminium chassis is a premium touch and the switched-mode power supply is internal. Many competitors rely on chunky external power supply bricks, and some encounter overheating due to inadequate cooling.

WiiM’s fully passive cooling solution uses a PID thermal control circuit, a copper heat pipe and a large aluminium heatsink – PC assembly enthusiasts will feel right at home! During my listening tests, the Vibelink Amp reached a maximum of about 15 degrees C above ambient temperature after several days of continuous use. I didn’t trigger the amplifier protection circuit, so the cooling design definitely works. Also, the amplifier will power down after a period of inactivity, which is great in a world of rising energy costs.

During The Firebird, another Watford gem (Classic Records/Dorati/LSO), the ECI 6 allowed the spacious acoustic and the pinpoint imaging achieved by the original Mercury recording team in 1960. Also, the very demanding dynamic range of this pressing (Bernie Grundman cut) presented no problems to the MKII. The control of bass during the bass drum heavy Side 2 was very impressive on transient, note and decay. Excellent control.

The MKII is said to have an improved power supply, and this new version never gave me an ounce of power envy. At times, however, the massive headroom of the MBL allowed a more refined, effortless playback—an ease that only gobs of brilliantly engineered power through the right speakers can bring. In my case, it’s not about speaker matching, though that is important; it’s a comfort and peace of mind thing. And if you hear one of these 20 K plus integrateds, such as examples from MBL, D’Agostino or Accuphase, you’ll know what I mean. The Bugatti Veron rarely uses its 1000 hp, but it’s there underfoot, and the driver knows it and feels it.
