Why not horns?

Prdprez, John Dunlavy also thought the step response was the most important measurement.

"Perhaps some evidence to support those claims might be appropriate? "

Perhaps.

The OHMs seem to work and sound as claimed as best I can tell. I see no evidence to indicate false advertising or other less than honest business practices.

Also I am sure most OHM customers don't care about technical details. Listening is all the proof that really matters.

Again, if you have questions regarding the technology, best to address them to the man who knows the answers, John Strohbeen. I'm always interested to hear what John says. I find it almost always understated but accurate.

Again, I'm not the one making the claims.

I wonder if John Bau gave this matter any thought when he created the Spica TC-50? When was that, like 1982?

"Again, I'm not the one making the claims"

No, but you are questioning them. All vendors make claims. If you have questions, you should ask and get the answers.

I believe the claims to be true based on what I know of the design and what I hear. But that does not prove anything especially to a skeptic now does it?
