Removed the grill which removed a "veil" from midrange 😆 and had to rework the crossover and physical alignment of the supertweeter, but yeah, I'm beginning to think the speaker angle was already a solved issue in the 1950's and 60's..

I got SO lucky with a local listing. Altec A7-500, and I added the supertweeter.

Huh, looks like somebody is emulating the vintage JBL LE85 "Potato Masher" Horn concept, likely an effort to manipulate sound dispersion.

https://estatron.com/collections/all Somebody who studied Head Case is now building and selling a 'stat energizer. Kind of interesting because it's only $160. Worth it?

WE300B tubes were only making 5.5 watts vs 8 watts of Shuguang 300B-Z in this video. It's a bit puzzling and I wonder if other 300B tubes may be a better option in the 'stat amp?

I can hear people warming up their Stax 4070's...

What's the price on Ray Samuels B-21? Just to get perspective on Eletrostat/Dynamic combo amps out there.. Audio Valve Solaris $4900 https://www.headamp.com/products/audiovalve-solaris Mal Valve Head amp three Mk 4 6000+ Euro https://www.malvalve.de/Headamp3-E.htm Linear Tube Audio Z10e $6950 https://www.lineartubeaudio.com/products/z10e-electrostatic-headphone-amp-integrated-amp

Makes ME feel good about my soldering skills at least 😁 Shouldn't this Viva STX stuff be posted to Head-Case Viva STX thread so that other people seeking wisdom can find it in google search?

Why does Devore O/96 sell for $16K when it's a copy of the Audio Note copy (some say pirated without paying license) of Snell type E/III?

I sure hope this Topping EHA5 transformer box turns out to be reliable and good-sounding, not causing harm to 'stats, etc. The masses need a 'stat transformer box that is readily available from a "big" company. BTW. Why the heck did Stax stop making tranformer boxes anyway?

ZMF has many fanboys, but take a look at this (for measurements): "Heavily boosted upper bass lack of energy in lower treble" https://www.audiosciencereview.com/forum/index.php?threads/zmf-atticus-review-headphone.24191/

He said in an interview he has the driver manufactured to his specs from China. Then again, where else?

I love these types of speaker designs. 1.4" compression driver is a nice touch. I assume Reflector Audio and this top module can be used without subwoofers, in which case what are their useful low frequency response?

Which "PC" are you powering? I've tried quite a few different power supplies for my PC/server, and the largest difference in SQ seems to occur when better power is given to the very end of the PC signal chain. For example, if using USB out, giving decent power to the USB card. Giving good power to an outboard usb-to-spdif converter makes a large difference also.

I noticed both Nahre Sol and Jimindorothy are Korean musicians. K-Pop is not all there is...
