Biamping with very different amps

Hi George,

The KUBE would allow the gains of the two amps to be matched without using a separate passive volume control. See section 3.6 of the following document:

Hi Al, not on the Kube I once had used, looks like the op’s one is different and has high and low gain controls, if so and he has the range to match the amps, then yes no need to use a Schiit passive then. If not get the Schiit is only $49. That way he can also do it without the Kube in, as it’s full of opamps TL071/2 from memory, and they sound very soso in the mids and highs.

I stand corrected. I misread george's post.

The 107/2 KUBE has both HF and LF level controls.  I've tried the 107/2s with and without the KUBE, and prefer their sound with the KUBE.  As I understand it, the 107 and 107/2 KUBEs differ substantially.  The 107/2s remain among the best sounding speakers I've heard, and driven by the JC 1s do a credible simulation of the sound I hear at pipe organ recitals and jazz clubs.  I've abandoned the crazy idea.

I’ve abandoned the crazy idea.

As I said It’s not crazy, you said you have Kube level controls over both highs and lows .

The Kube drives all your amps JC1’s on the bass and Cary’s on the mid/highs.

You use your JC 2 BP as your main preamp to drive the Kube.
