Those of you with KEF R7 Metas: how happy are you with them and how are you driving them?

The R7 Meta is a 88.3dB@2.83V/1m sensitive speaker so moderately easy when it comes to voltage swings. It however is a 3.2 Ohm Minimum impedance speaker so you need a 4 ohm stable if possible 2 ohm stable amp to give the speaker the current it demands so a high current amp is very much what to get. Do you have a Preamp?

@howardlee I'd say use the Pass labs as Preamp and get two of this Monoblock that is stable down to 2 Ohm. With incredible current drive and stable at all loads so are not load dependent.

 

Have tons of voltage swing to make sure the speaker movement of cone is aligned.

 

Get two of this - https://www.buckeyeamp.com/shop/amplifiers/hypex/ncx500/monoblock

Power delivery: 700 watts @ 2 ohm, 700 watts @ 4 ohm, 380 watts @ 8 ohm

You have so much headroom with this that you'd never lack for power delivery.

 

You'd connect them through the XLR Preamp Outs on the INT-60 and carry that signal via XLR interconnects to each monoblock XLR input.

 

Get two of this cable. Robust, does the job and doesn't get in the way of the signal - https://www.amazon.com/Units-Balanced-Microphone-Amphenol-Connectors/dp/B074XSDCG6
