Tube Preamp/solid pwr amp or solid pre/ tube pwr

Well, it appears as if I'm in the minority, but I have found that a tube pre-amp and solid state amp sound wonderful. But, (huge but), this, in my opinion would totally depend on your price point. Like cars, upper mid fi to lower high end components (tube or solid state) are in my opinion not much different sound wise. But, when you go up in the high end chain, I can't really say whether one or the other is better, but there are sonic differences. there are pros and cons for both mid to upper high end tube and solid state. I'm not in the group that thinks that tube is better than solid state or visa versa. I hear equipment all the time, and to me, I would take quality tube or quality solid state equipment. either one. you have to listen often to different equipment in your home, on your system (one piece at a time). Don't change anything else, not cables, etc. just listen. Make sure you are comparing apples to apples. i.e. equipment within the same price points. otherwise it really isn't a fair comparison.

Hi Minori,
I don`t see where anyone has said tube pre with SS amp can`t sound wonderful.The point being expressed(at least to me) was that tube amplifiers are more likely to provide what was called the"tube effect"(system influence) more dominatly than a tube preamp more often than not. There are numerous ways to constructing a satisfying audio system without question.

Keep the tube pre. Buy W4S stereo or mono amps and enjoy.

I think Raquel nailed it. I have long had a tube pre with a SS amp exactly because I can't afford a very good tube power amp. I can, however afford a good SS amp. I paid a bit under $1500 for a new, one-off Odyssey Stratos HT3 with cap upgrade. For my speakers, which, like your B&Ws, need fairly beefy amplification, $1500 for a tube power amp would have gotten me nowhere.

Other factors to consider:

Heat. A tube pre won't generate a significant amount of heat, but a tube power amp usually does. If you don't like the idea of sitting in sweat while you listen in the warmer months, a cooler-running SS amp is preferable.

Reliability. All tubes can fail, but tube life in most preamps exceeds tube life in most power amps, and biasing is usually not an issue, so a SS amp requires less care and feeding. I once had my dad's old Bogen tube integrated catch fire. Yes, I am scared of a tube power amp.

Impedance matching. My previous pre was C-J PV-11. A great preamp, for sure, but until I upgraded to a McIntosh (a brand known for tube preamps that play well with SS power amps), I didn't realize that I was missing about an octave of bass on the bottom. With the right power amp (SS or tube) I am sure the C-J could reproduce that octave, but with the Stratos, it went missing. I almost fell out of my chair when I hooked up the McIntosh and played some music with deep bass in it.

I have no idea what the impedance matching issue is for SS preamps with tube power amps.

I don't ever recall hearing the B&Ws with tube power amps, either at dealers or at shows, FWIW. B&W owns Classe, and I have heard Classe SS amps (and preamps) make nice sounds with B&W speakers. That doesn't mean tubes won't work, just that the folks at B&W might not be thinking along those lines when they voice and design their products.

Lastly, consider a hybrid power amp, like models from Aesthetix, Vincent or Butler. You get the benefits of a tubed input stage without the challenges of a tubed output stage.

Lots of advice offered both good and bad. You might look to see how many own N802's. I did, and they all own something else. So, there's a lot of conjecture going on.

The idea of Classe being a dream match is just that, a dream. I had Classe amps and I had decent sound. Ultimately too lean through the midbass and lower midrange and a propensity for midrange glare. The W4S amp trumps them in every category.

The VAC tube amp is not bad at all on the N802, better then the Classe but not as good as the W4S.

Let me make it clear, I'm not saying the W4S is the best SS amp, it is the best match I've heard on the N802 coupled with a tube preamp. My W4S amp does have the WBT output terminals and I use a power cord that cost as much as the amp so that may skew the results of someone else using a different configuration. The results speak/sound for themselves.
