No. As long as it refers to a person, it is liable to make people unhappy. Just explain why you think tube electronics is a better fit than solid state and let that speak for itself (or not).Is inexperienced better?

Hello, Keith. While it may not be a technical reason, ones ears may consider the sound to be bright or piercing. At least that's my own personal experience with the combination.Is there a technical reason not to use solid state amplification with horns?
Keith
There are Keith but I'm not the one to explain it, there are others here who can explain the technical issues better. Here's a very basic explanation in this article.Is there a technical reason not to use solid state amplification with horns?

As all rules of thumb created by experience, we can have exceptions - but IMH experience in this case they are due to un-explained technical reasons. Avantgarde designs a solid state amplifier that I have listened sounding really excellent with their own horn speakers.
But, in general, I would say that the few times I listened to horns powered by solid state the sound quality was very poor.
I have read that some people use the DartZeel NH108 with horns - although I still own the former I do not have the horns to try with it ...

I don't know what you've heard Tim, but your description of their sound is way different from most of us who live with high end vintage horns! PA? Active bi-amping to lower noise floor and better dynamics; WTF? This is rubbish! Only the clueless use solid state with 100+ db sensitive vintage horns .

Some design aspects of my vintage gear exceed stuff I see today, and other things like acoustic isolation and such are not as good. However, it does deliver, and continues to deliver pleasing sound. Speakers, now that's where there have been huge advances IMO. Except I am less interested in speakers and more into headphones now...so it balances out some...ironic.
One thing though, all my gear is spec'd, so I can have a rough idea of my total system distortion, which when compared to most high priced current gear, the specs are not even there that was there on older gear, when consumers were getting that kind of information from the audio manufactuerers.
I was listening to my "vintage" ( can we call it that since this amp is from the early to mid 80's) ARC D70mk2 tonight. I really have to say that it seems to me that perhaps we have not come that far in amp design since then. Earlier in the day, I had the pleasure of listening to a friends new Classe CA 2300 amp and his B&W 802 Diamonds. Frankly, the newer amp really wasn't as nearly as resolving as my older ARC. On the new release of Doug Macleod..."Exactly like this" on Redbook, the sound of Doug's guitar and his dobro was far more realistic on the older tube amp than on the much newer Classe.

You listened to two different systems, in two different rooms, with two different set of speakers, at two different times and you could tell that one of the amps wasn't nearly as resolving as the other?

And I can only assume you've not heard top quality PA, which is what I was referring to when I spoke of active, not vintage horns. I didn't get my description of vintage horns right? Which part did I get wrong? Coloration? Remarkable headroom even with low-powered amps? Great dynamics at high volume?
Tim
You mean this?
"The first problem is electronics. Weiner talked about listening to some Klipschorns with high power solid state amps. The amps were one source of the bad sound. Horn systems typically have sensitivities of 100 to 108 dB SPL with one watt input. Even at the loudest sound that you would realistically audition any speaker system (95-100dB), the amplifier is only delivering a watt or so to the horn system at peaks. Most of the time the amp is idling at 100's of milliwatts; yes, I said milliwatts. At this level many high power solid state amps have real problems with crossover distortion. For this reason, I tell people who buy my horn systems to try different amps with them along with their existing amp. The low power requirement of horns means that single ended tube (SET) amps can easily fill a room with sound. However, not all single ended tube amps are created equal. Some SET designs have relatively high levels of distortion that can be easily heard on the horn system. And of course, the horn gets the blame for the distorted sound."
What crossover distortion? Here is the first hit on measurements of amplifiers from stereophile, the Solution 710: http://www.stereophile.com/content/soulution-710-power-amplifier-measurements#zKc9WavQQksAVp6m.97
At 1 watt, it has THD+noise of 0.005%. And it puts out nearly 200 watts so clearly falls in the category of high-power amplifier. Since the graph declines until about 100 watts, what is there is dominated by noise, not distortion.
Class AB solid state amps are biased to not have crossover distortion at low level. To say nothing of feedback network.
And here is the first hit on a tube amplifier, the Air Tight amplifier: http://www.stereophile.com/content/...er-amplifier-measurements#psEc84fkvFLAYJ1E.97
The THD+N ranges from 0.1 to 2% at 1 watt. Unlike Solid State amp, this is all distortion, not noise at this wattage.
Is there something more authoritative than this little bit to explain why tubes are better for this type of loudspeaker?
Actually I've been buying & donating vintage PA systems for years. My bad the way it read you were comparing PA systems to domestic & theater horns and that's what people were bi-amping. I still don't see what bi-amping has to do with reducing the noise floor of the speakers.
