Biamping with a tube and SS combo


I was watching a youtube video by Paul @ PS Audio in which he was discussing the differences between bi-wiring and bi-amping. An interesting point he made was that some folks like to use a bi-amping configuration where a tube amp is driving the tweeters, whereas SS is managing the woofers. I've read a lot about tube pre's working in conjunction with SS amps, but never really thought about this particular combination. Sounds intriguing. So inquiring minds (and mine as well) want to learn a bit more from those who might have travelled down this road ...

How would you compare the bi-amping scenario I described above with the more common tube pre + SS amp combo? If you have compared both, which one sounded better to you?

If one were to go down this path, what aspects one has to keep in mind? E.g. things like impedance, gain settings, etc,

If you have one source only, which one do you connect it to? And subsequently, how do you connect the tube and SS (same as the pre/amp combo?) ?

I would love to hear from folks who have actually tried it, and not just throw a bunch of measurement graphs at us. Also, let's not turn this into a bi-amping vs bi-wiring comparison or tutorial. Thank you.

I've seen Bi-wiring make a difference when there was a cable size issue, I've seen good single runs with good jumpers, work well also.

Bi-amping, I personally think it's the best of both worlds.
I use valves 300hz and up.
I use SS 300hz and down.  300 hz is pretty high, do a tone burst from your phone. It's pretty high..

Depends on your crossover, if it's a 2 way system, it's usually to high, to make a "GOOD" difference. 

Happy Holiday

Thanks everyone for such informative posts. As I mentioned earlier, I wasn't aware of this specific configuration and was intrigued. Appreciate the education. Right now, I'm enjoying my Luxman 590axii integrated amplifier, but I'm thinking down the line I would like to add a tube preamp in conjunction with the Luxman and see how it affects the sound. I don't think I will pursue the setup I mentioned in my original post. I'm not as savvy or knowledgeable as some of you folks. It's much more likely that I might end up making matters worse.
I have a tube preamp feeding sonically transparent solid state amplifiers and enjoy the combination a great deal. Perhaps I'm biased because of that, but I believe you've made a good plan.  Plus, preamps often run tubes more conservatively than power amps, so it's likely to reduce your tube costs to put them in that location.

There are plenty of relevant threads to review, just search for tube preamps recommendations and you'll see an overwhelming number. My personal impression after investigation was to focus on 6sn7-based designs (e.g., users seem to universally praise Supratek and Don Sachs pres). Although less popular for manufacturers due to microphonics and noise issues, there are also a lot of dht adherents out there as well. I'm about to get one to try against my idht 6sn7 pre.

Anyway, good luck with the search, it should keep you busy for a while...
