Biamping, bass and amplifier type.


I am new to the idea of tube amplification, but not new to the audio hobby (or obsession, depending on your point of view).
My question is, if tubes provide decidedly better treble and mid reproduction and a better image and soundstage, and if solid state provides better bass extension and response, why not use biampable speakers with solid state wired to bass and tube wired to high/mids?
OR
Tube amp for high/mid satellites and a SS sub?
Wouldn't this provide 'the best of both worlds?'
I look forward to your responses.
This is important to me as my amp of the last 25 years just died and I am venturing into a new system.

Valid points are made here, I do not disagree with them. However I am coming from a place of personal experience in a real world system that I owned.

The difference in the gain was not audible to me. Never thought to pay any attention to it though, that being said, it never called attention to itself enough so that I felt I needed to. I simply found it worked for me and enjoyed this setup for many years.

As far as bass quality, the BAT S.S. product was deeper tighter and had more slam than the VTL even when it was run in Tetrode. The other benefit that may be worthy to note is the BAT VK-500 could handle the demands of my speakers on bass heavy material much better. Both are high current designs that can drive almost any speaker but the when the peaks hit... the VTLs would blow fuses. When I set the BAT up to run the bottom end the fast blow on the MB450's stopped popping for no apparent reason.

For the what it is worth department. I am of the camp that does not particularly see any real advantage of tube vs solid state offerings. So my input does need to be taken with a grain of salt if your are a tube guy.

I have had both, absolutely loved both for their strengths and weaknesses. My experience has been, a well voiced and engineered product in either camp is enjoyable. For me it is more of the interpretation of the music that the component does vs one technology being superior to the other. Much like different conductors will not interpret the same symphonic work the same way, each bringing various nuances out of it that the other does not see. I would be hard pressed to say that Karajan's conducting is more musical than Dorati's.

I really want to thank everyone who has responded to my post for their well reasoned, thoughtful and well written replies.
Class (A) all the way.
I agree with Bob, save yourself the cost of an additonal amp and get a quality subwoofer. A subwoofer will produce way more bass than a biamped speaker.
I've biamped in just the way you're considering: a ss amp to the bass cabinets of my vr4 iii's, and dynaco mk iii monoblocs powering the mids and trebles. Though my ss amp puts out 170wpc, and the Dynaco's are rated a 60w, gain difference is not an issue b/c of two convenient configurations in my amp and preamp: 1) my ss amp has volume pot (per channel, but a single pot controlling both work just as well); and 2) my preamp has two sets of outputs. Those aren't requirements by any means, but it makes bi-amping a cinch. I keep the volume pots on ss amp at about 4, and then leave them alone; everything is controlled via the preamp, and I don't notice any imbalances across the volume range. And with the VRiiis, which get down to about 20hz, no subwoofer need apply.
