Devore or Audio Note or other sensitive speakers: wanting to listen in Denver

I'm on the hunt for a sensitive speakers to play really nicely with my Quicksilver Mono 60 amps. I've heard some nice Spatial X3's here in Denver thanks to a local audiophile. I was especially taken by their AMT tweeters.

If you're in the Denver area and have Devore, Audio Note, Zu, Tekton, or any other speaker which has really worked well for your tube amps, please DM me. I would be deeply grateful for even  an hour of listening time. Thank you!

@jjss49  Wise, as usual. Thanks!

@drugolf I've mapped it. 8+ hours but a lovely drive. Maybe.
@steveyork -- Thanks for the suggestion. That might be fun! Didn't know about Prana. They are close to me. Will try to shoot you a DM in the new year!

Easy to drive 8 ohm impedance and 95 db sensitivity is a very desirable combination.

@charles1dad re Fyne- Can you point to the easy to drive 8 Ohm impedance? I can’t find any curve info except for the 501, which says 3 to 30 ohm with nominal 8. I’m thinking with a recommended amplifier minimum of 20 watts per channel, most are similar.

I’ve never seen much on the impedance curve with Tannoy either and know most use medium wattage, but many are happy with SET amps too. I can see the impedance "challenge" with very high sensitivity rating could make for a really fun dynamic and powerful/explosive experience with the recommended amp rating. With less power I wonder if one might wonder about unleashing the beast in the speaker?

Really cool looking designs and with Tannoy being a little lost in space these guys have found an attractive stage to perform on again. Is the high frequency driver in these two brands the same? Similar crossover at 1500? Tannoy has the tulip, Fyne has the isoflare. Kind of reminds me of that McDowell’s scene in Coming to America. "They have a sesame seed bun, our bun has no seeds..."

This is from the Fyne Audio web page in regard to the F1 model range. I've  not come across an independent source measurements and graph site.

From JA/Stereophile

Although the Fyne F301's specified sensitivity is a high 89dB/2.83V/m, my estimated sensitivity was slightly lower, at 86.2dB(B)/2.83V/m. The Fyne F301's nominal impedance is specified as 8 ohms. While the impedance magnitude (fig.1, solid trace) remains above 8 ohms from the upper midrange through to 30kHz, it does drop below 8 ohms in the lower midrange, with a minimum value of 4.77 ohms at 200Hz. While the electrical phase angle (dashed trace) is high at some frequencies, the impedance magnitude is also high at those frequencies. The Fyne F301 will thus be a relatively easy load for the partnering amplifier.

So overall is considered an easy speaker to drive.

Well done, Charles1dad. The devil is in the details. I tried some Focal 936 towers because they listed at 8 ohms, 92 dB sensitivity. However, when one looks more closely:

"My estimate of the Focal’s voltage sensitivity was 89.5dB(B)/2.83V/m—close to the specified 90dB, and usefully a little higher than average. The Aria 936 is specified as having a nominal impedance of 8 ohms and a minimum impedance of 2.8 ohms; my measurement (fig.1) confirmed the minimum value at 108Hz, but as the impedance stays below 4 ohms from the upper bass though the lower midrange, where music has high levels of energy, I would recommended using a amplifier rated into 4 ohms with this speaker."
