Question about Insight 240 Power Amp
« on: 5 Mar 2010, 05:58 pm »
Is it possible for the Insight 240 Power Amp (the compact chassis) to accept bi-wiring for the speaker cables?  Any information would be appreciated.  Thank you in advance.

Typical bi-wire cables have two connectors(spades/bananas/barewire) on the amp end and four connectors on the speaker end(per channel)...will work fine w/ the small Insight 240. If you are using two separate sets of cables, you can generally stack the hots together and the commons together at the amp end if you have spades or the correct style bananas. If using bare wire, simply twist the hots together and the commons together on the amp end.

The wiring would not be 2 separate cables, and they would be terminated with spades (at the speaker end, at least).  Could I use bananas on the amp end (will the 240 accept bananas) or should I use spades on the amp end as well?

The simplest way to connect two sets of speaker wires per channel to an AVA amplifier is to use Pomona stacking double banana plugs.  One set (and pair of speaker wires) plugs directly into the speaker terminals on the amplifier, the second set plugs into the first set.  Easy.

I do not recommend spade lug connections, especially trying to connect two spade lugs per terminal.  They turn, they twist, they short together, they come loose and fall off, and when you take a pipe wrench to the connection to "really" tighten them, you break the speaker terminals clean off.  That will really make a change in your sound you can hear.

I biwire my HT3s and Ultra just the way Frank describes.

I absolutely agree with Frank- Pomona bananas are all I use. Even the single bananas are easier and safer to use than spades or bare wires- the doubles are absolutely the safest(pretty much klutz proof).

I went to the Pomona website and looked at stacking double banana plugs.  Would the model 1330 work for what I am trying to do, or would someone suggest a different model?

 1330 is the correct one. The single version is 1325. A helpful bit of knowledge- if you check the PDF file for the 1325, you will see that these plugs are designed to use 22AWG to 18AWG wire. They will actually take 16, 14 and 12AWG as well. I don't see this on the 1330 PDF file, but the wire opening and set screws are the same.
