Would love to see photos of the Jota. Loved the sound of their PX-25, which I got to play with years ago. Had a number of customers using Jotas on the Talon Khorus back in the day when I used to work for them. Wonderful Amps!

Mine is the high current version requiring high current 300B's (300BXLS). Limits the tube rolling options for sure, but it gets almost 22wpc out of an SET. I've had a lot of amps pass through my hands over the years, and this one remains my favorite.

The stock crossovers will need some work, they use sandcast resistors (ew), film caps, iron core inductors. Will most definitely be swapping out the resistors, likely the inductors, and MAYBE the caps if I can find equivalent values at better quality (the crossovers use some very oddball cap values). All of the Klipsch drivers are proprietary, can't say how they compare to other designers specifically, but I will say the most recent iteration of their Heritage line (version IV) has been very well received. I've seen members on Audiokarma say they would take the new Heritage line over vintage Altecs like the model 19 and many old JBLs. Pretty hard to find a bad review of these speakers, specifically the Forte IV and Cornwall IV, most everyone seems to say they are a knockout. The horn speaker / high-sensitivity speaker market is pretty small, I've signed onto living in that niche given I am running single-ended class A tube amps. My 801A amp is a beastly 7-watter :) the 99dB in room sensitivity of the Forte IV is a good match, loved what I heard from them when demo'd. Other players in the high-sensitivity market that aren't ultra expensive are Volti Audio, Zu Audio, Omega, Fern & Roby...open baffle is another option but again, not great having exposed wires / drivers with cats. Klipsch is a nice choice since they are a mainstream brand that isn't bonkers expensive, I don't have to cry if something breaks, I can just get it replaced without too much stress.
Add Tekton to the list -- my Lores are 98dB sensitive and rock the house with 22 watts. Rather unconventional design by audiophile standards (whizzer cone guitar amp drivers, anybody? :laughing: ) but they're a lot of fun and pretty cheap to boot.

Oh yeah, totally forgot Tekton Design! Right there with the rest of them sensitivity-wise. Decware also has some pretty high-sensitivity designs.

Zach sends me unfinished black and white ebony VC cup photo. Will be finished in a gloss, should make the contrast pop.

OK, I'm officially jealous. That's gorgeous!

That's the wood I always dream of for a VO, I even asked Zack if he would be able to take a custom order but he denied because of workload, this was in 2020.

Yes, he is quite busy all the time these days!
Especially after the ZMF November event.
This was in exchange for the custom amplifier I made him recently.

Hot Damn that is one sweet amp. I really wanted to get an Art Audio Amp was close to getting one on incentive pricing. Just didn't quite work out. But I talked to 4 or 5 customers that swore by this high current version on thier Talon Audio speakers. I will bet that thing looks ridiculous in the dark when it switched on.

Thanks for sharing,

OMGosh that is stunning. I really like darker wood. My Auteurs in Blackwood and my VC's in Leopard dark stain, but wow really nice for a lighter colored wood.

I've been curious about Decware's horn and slot loaded designs. It's interesting how Omega, Zu and Tekton all get pretty different voicing out of similar full range drivers.

Those are going to look killer, Keenan.

Zach told me if he hits the cups with a wipe of alcohol, you can see what they are going to look like to a certain extent.

I bet you can already picture them, right beside one of you amps :)

Please post some pictures when you get the final product.

I sure will. Here is a pic of the bookmatched cups before sanding.

Worked on the bronze Airmid today, made some good progress, think that will be all for now, off to do some yoga 🧘‍♂️
