Effect of bi-amping?? Marten Design & Dartzeel

i've asked the Dartzeel distributor this very same question during a home-demo just over the weekend (system consisted of Emm Labs > Dartzeel > Coltrane & full Jorma Prime cables). a pair of Bladelius Beowulf (900w/ch into 4ohms) were also on hand for A/B comparison.

i preferred the Dartzeel in certain areas, but naturally, the Bladelius had better control, agility, & less smearing abv 90dB. when i inquired whether these areas can be improved with the addition of a 2nd Dartzeel (in vertical bi-amp), distributor advised to add a crossover when doing this (otherwise 'timing' may be off). no idea if this is true or not, but anyway, i've still got a few more amps to demo.

I'm curious about your Distributors statement Alexsee.

Are there any people on here that use 2 Dartzeel in verical bi-amp mode that can share their experiences? Do there experience any "timing" usues?

Thanks

he didn't go into much detail, but did suggest me to get a Dartzeel preamp b/f trying to bi-amp (was told the preamp reduces background noise, & helps improve image solidity considerably).

other than 'control', 'congestion/smearing' issues (during complex passages at louder vols.), i was fairly impressed with this amp (esp. since it's only rated 160w/ch into 4ohms). when i enquired whether Dartzeel has plans to release a larger amp, was told they will be releasing an integrated amp next.
