72-140-180 combi

[Brandbyge]

Hi

I have the 72 and 140 and love it, but thinking about ading a 180 to this combi and do BiAmp on my Snell A2 Without ading a Hicap ..

Is this possible ?

Welcome to the forum Brandbyge.

You can run the NAC72 off the NAP180 in place of the NPA140, however, if you wish to use both the NAPs together to bi-amp then you’ll need a power supply on the NAC72 such as a HICAP, which provides the required pair of stereo signal-outs.

Frankly, passive bi-amping gives limited gains and you’d be better off here either just getting a HICAP, which will improve your NAC72 and relieve your NAP140 of pre-amp powering duties (so double gains), or else, get the NAP180 and trade your NAP140 for a HICAP.

Or, even better, buy a 250, sell the 140 and either the proceeds get a Hicap. The 72 / HC / 250 is a classic for a reason and will be way better than 140 and 180 biamped.
