Biamping Triode Tubes No Feedback With Solid State

I agree with Matrix's point that biamping with passive crossovers and 2 different kinds of amps is difficult.

I disgree that one needs--or even that it's a good idea--to strip all passive 'crossover' components when actively biamping. Doing so with a 3-way speaker requires one to triamp; biamping actively is difficult enough. Also, most 3-ways have band-pass filters--those that block lows from the bottom and highs from the top--on the midrange driver. Removing it from the crossover requires one in the active crossover.

Also, some speakers have equalization networks in them to level their response. Removing all passive components eliminates the very real benefits of these eq. networks.

I'm all for biamping actively, 2-way, and with the fewest number of components and IC cables and mechanical and solder joints, all of which degrade the quality of the sound to varying degrees. My active high-pass filter has NO mechanical connections and only one extra solder connection per channel. The four pieces of interconnect cable are hardwired to my Dalquist low-pass filter; that eliminates 4 mechanical and at leat 4 solder connections from the low-frequency section. Those who think that active filtering is all good and has NO negative affects on sound quality are wrong IMO.

Good listening.

Well yes you could keep the simple tweeter circuit in there true, and go 2 way bi-amp I was just simplifying, bottom line it gets tuff and expensive to do it for real. and the efficiency of running 2 totally different amps for bi-amping drops quickly with cost and simplicity of system.

The only real way is to go with 2 Already excellent matching stereo amps and Verticle Bi-amp then you could leave all the passive components alone.. but this is not what you are looking for, you want basically to turn the lower woofs into solid state Sub's(not literaly but essentially) and the top to run on the sweetest tubes, this cannot be done without a very good Active Crossover and full active bi-amp system, with speaker modification. and even then getting it all to be peak level and optimize all other problems gets complex sometimes.

I am serious about the Cary 300 sei.I was thinking about using the Vandersteen Quatro with its powered bass or the Zu with powered bass.Any other speakers like these and has anyone gone this route?
I know Aurum has a system only set up where a 300 b amp and a solid state amp are combined as one amp but this only works with their optimised speakers.But, what beautiful sound.
