Aerial 7B amp recommendations


I am enjoying a pair of Aerial 7B speakers I just bought used. I am using a modified McCormack DNA-1 amp with a bigger transformer. Somewhere just over 150 wpc, so they told me. Is this enough power? Those with experience?

I run my 7Bs with a Pass X250 and have used various other amps from 100, 150 and currently 250 wpc. Why experience with each jump up in power the 7Bs open up more and everything improves across the board. If you enjoy how they sound with your current amp, that’s really all that matters. The McCormack is a nice amp so I wouldn’t dump it for a lesser bigger amp.

If you don’t have the optional Sound Anchor stands they are a must. I run mine with single run cables and biwire with jumpers at the speakers. I found wire jumpers improved the sound over the stock metal straps. Experiment how you configure the jumpers as I found it does make a difference, although subtle but it does. Notdost Cables used to have guide on how to use jumpers which I followed and prefer, but again experiment.

If you don’t have a dedicated power circuit to your system you may be surprised how much that will help your amp along with a decent power cable suited for a power amp and a hospital grade or better receptacle. Doing this was one of the biggest improvements I heard through my 7Bs, as if my amp was starving for power.

Congratulations on your new set up and especially your 7Bs.
@n80 If your cables are a biwire set as you mentioned you don’t use jumpers. A lot of people prefer to use a single run meaning amp and speaker end has only one set +/- and then use jumpers at the speakers. In your case make sure the metal jumper straps are removed on the speaker binding post.
