Kinked. It's better than coming unglued. You'll see.

The emailer was Ken Ng. He's Alvin Chee's partner at Vinshine Audio and responsible for Kinki Studio's sales & marketing. "We've released updates for our EX-M1EX-M1+ and EX-B7. We don't call them new models but over the pre-2020 precursors, they are essentially new. Moreover, we've released our first stereo amplifier, the EX-M7. Would you be interested to review one of them? We think that either the EX-M1+ or EX-M7 could be of interest to you."

Thinking on whether readers would rather learn of the next incarnation of Kinki's best integrated whose last life we've covered before; or about a brand-new stereo amp – I unilaterally opted for the latter. Executive privilege. But really, here's why: bandwidth of 0Hz to 2.5MHz ±3dB! A-weighted S/N ratio better than 130dB. Slew rate of 200V/us. Twin 400VA toroidal power supply for 72VDC and 18A peak current. Two pairs of Exicon lateral Mosfets.

The amps I like best happen to overlay such specs. I fancy wide bandwidth, class A/B, direct coupled and Exicon laterales. Be it Bakoon's AMP-13R or LinnenberG's Liszt, something about their shared general topology has wormed its way into my ears over the years. Now I'm hooked. And where we live, there's no Audiophilicus Anonymous.

At 25kg, this Kinki is no lightweight. Aside from XLR and RCA inputs, the business end also has defeatable DC filtering. That's great if your power conditioner lacks it but transformers hum. Flick a switch and… silenzio! Input sensitivity is a usefully low 1.45Vrms. This amp won't eat up all your preamp's gain in just a few clicks. Dimensions are a typical 37.5 x 43 x 11cm WxDxW. Idle power consumption is a low-ish 30 watts. At max output, one could draw up to 700 watts. Yet one's ears should clip well before that. Finish options are black or silver.

For less than €3'000 direct from Singapore, Kinki Studio's new high-power amp read and looked far too good to refuse.

So I didn't.
