Is bi amping worth it ?

@hardhattg,

My advice: sell the MC 601’s and buy the MC451 1-Channel Dual Mono Amplifier.

That said, passive or active bi-amping should not be undertaken without first asking the speaker manufacturer’s advice. Hope that helps. 😎

Passive bi-amping is fine to try if your speakers have two sets of binding posts, one for high frequencies and one for low frequencies, as long as the two sets of posts are completely isolated electrically from each other.

There have been speakers (and may still be) that share grounding between the two sets of posts and shouldn't be passively bi-amped.

This can be easily determined with an ohmmeter.

As far as active bi-amping is concerned, the internal crossover needs to be bypassed entirely and the speaker must be modified to that effect.

I cannot imagine any speaker manufacturer would happily recommend advising to do that.

below is the fairly simple passive bi amp I believe will work with just two monoblocks 
 

Yes, it is possible to passively bi-amp Klipschorn speakers using two MC601 monoblocks and a C2300 preamp, provided that proper setup procedures are followed and all equipment is compatible.
Passive Bi-Amping Klipschorns
    •    Klipschorn speakers have two sets of binding posts to allow for bi-amping, using the existing internal passive crossovers.
    •    Remove the jumper plates between the LF (woofer) and HF (mid/high) terminals on each Klipschorn. Each MC601 then independently powers either the bass or the mid/high section of both speakers.
    •    The C2300 preamp has two sets of outputs (RCA and XLR), which can feed independent signal paths to each MC601. If only one output type is available, a Y-splitter can be used.
    •    Passive bi-amping increases available power and current to each section but does not bypass or alter the speakers’ internal crossovers or frequency division.
Required Steps
    •    Connect one MC601 to the LF terminals and the other MC601 to the HF terminals of both speakers. Ensure that the jumpers linking the LF and HF terminals are removed.
    •    Connect outputs from the C2300 preamp to each MC601 input. Balanced (XLR) or unbalanced (RCA) cables are supported.
    •    No external crossover is required with passive bi-amping. The speakers’ built-in crossovers remain in use.
    •    Both MC601s should receive signal directly from the preamp, as each is tasked with driving a separate frequency band.
Considerations
    •    Because this is “passive” bi-amping, potential improvements are mainly in dynamic headroom and amplifier load-sharing, not network reconfiguration or electronic time alignment.
    •    Ensure both MC601s’ gains are set identically for balanced output between low and high frequencies.
    •    If uncertain about connections or speaker/amp protections, consult the official manuals for the MC601 and Klipschorn, or seek guidance from a qualified audio dealer.
In summary, passive bi-amping Klipschorn speakers with two MC601 monoblocks and a C2300 preamp is both feasible and straightforward—remove the terminal jumpers, cable each amp to the appropriate terminals, and connect preamp outputs to both amps.

was going to add a pic of the new khorns speakers connections. They seem to make no amping quite easy.  Not sure how to add a pic . 
 

thanks again everyone hoping to maybe play with this later today or tomorrow.   
also realized my dac streamer as a building equalizer and has a preset to add some bass.  Will try that as well. Allthough wont help with direct cd / vinyl

My tired old brain is still struggling to understand how this works but it may well function, I just don't understand how you would appreciate any kind of advantage. I'll be surprised if you do, as you are not really adding anything to the present system.

Have you heard someone else's Klipschorns that demonstrated better bass? What was driving theirs? Is it deeper bass that you are looking for? Klipschorns are known for being very effiicient and it sounds like you have more than enough power to drive them to their potential. I just don't know if they have the bass that you are looking for. I think I read 33hz as their bottom end. Does that sound right? Maybe I loooked at the wrong ones, not sure but if that's the bottom, I don't think any rewiring or re-amping will do it.

If you are using one 601 monoblock to drive the woofers of both speakers and another 601 monoblock to drive the high frequencies of both speakers, you are defeating stereo operation.  You are sending the same signal to both of your speakers, and are effectively operating in mono, not stereo.  Stereo soundstage operates by sending differing signals to the left and right channels.
