ribbons vs domes and sibilance

By the way, whether or not a dome tweeter is pistonic in audible frequencies is not a very esoteric question requiring laser diffraction measurements or anything like that. Just look at the distortion plots to compare tweeter A to B and that will tell you most of what you want to know.

I also just want to point out that modern "normal" domes (post 2000) are just sooooooo soo much better than the domes available in the 1980’s. Flat to past 20 kHz, go down to 2kHz? ,no problem!! And ring radiators? Amazing. This argument feels a little as if it were stuck back in the 80’s.

Worth keeping it all in perspective, that some users tweeter’s die and they barely notice it. 😁Why? Most of the music is in the midrange. It’s always fun to talk tech and possibilities of advanced motors, but audiophiles do sometimes get obsessive over the part of the speaker that produces the least sound. Want a really excellent speakers? You want a fantastic midrange.

@stuartk have you reached out to Silverline designer to get his take on your situation? Just a thought.

these speakers are 90.5db and 8ohms. It’s very possible that the design is intended for a low power SET amps. The specs are very similar to DeVore and those allegedly sing with SET amps. Your hegel could be too much of a good thing.

It’ll most likely come down to either changing the amp or the speakers.

@audphile1

Sent you PM in reply to your first question.

I intend to demo other speakers when my budget allows, starting with Fritz Carbon7SE’s.

RE: amplification:

The SR17 is fairly efficient (nominally 90.5 dB/watt @ 8 ohms), but more importantly it’s easy to drive - my Ayre AX7e, known for being rather limited in the power delivery department, sounded open and effortless. Alan Yun said the Dynaudio drivers love current and will benefit from powerful amplifiers, yet will sing with low-powered tube amps. I can confirm it loved the grunt of the 300wpc Bryston 4B Cubed, yet I never felt lower-power amps like the Ayre or Bryston B60 integrateds were lacking for dynamics. And my favorite pairing by far was with the 55-watt Valvet A4 Mk.II class A monoblocks sporting a single pair of bipolar output devices. (Incidentally, Alan’s favorite amp paring with the SR17 is the 30-watt Pass Labs XA30.5, which @mgd-taww can attest to being a magical combo.

When I first heard the Silverlines with the Hegel, I was astonished. My first thought was "This is the first time I’ve heard what these speakers are capable of".

My intention in starting this thread was purely practical: to gain some helpful information to use when shopping for my next speakers. 

OP: Nothing at all wrong with that. :)

I just wanted to point out that marketting hype and audiophiles tend to bias us towards worrying more about the tiniest motor in the speaker.

Some of the most sparkly speakers I’ve heard of late, BTW, were Magicos. B&W’s as well, and I attribute most of that to the choice of Mundorf caps. Go take a listen if you can.

Historically, to get some perspective, the Focal Be and Titanium tweeters had a lot of "sparkle" in them as well.  I always attributed this to a mechanical resonance inherent in them.

I made the mistake early on of pairing B&W's with Rotel and Creek on the basis of a showroom demo.

Once I set up this system at home, my ears found it quite painful. Important lesson!
